6 June 1944 - 25 July 1944

 

In the early stages of the campaign a considerable proportion of the stores which had to be imported into the beach-head consisted of supplies and petrol.The Directorate of Supply and Transport was faced with the problem not only of providing them on a very large scale but of transporting them from coasters to beach dumps and later to roadheads, the distance to which increased as the campaign progressed. Provision of the commodities was carried out without any great departure from normal principles but careful planning was necessary in order to solve the difficulties of their conveyance across beaches in proper quantities and sequence.

SUPPLIES

Each man in the force landed with two twenty-four hour packs which were for consumption during the first forty-eight hours ashore. Apart from these the only rations employed for a considerable time were “fourteen-man Compo packs”, which proved to be very successful.

Airborne supplies for the two parachute brigades of 8 Airborne Division were carried initially by packing normal first-line scales on the man and in containers, in addition to which all spare space in the aircraft and gliders was used to stow such stores as supplies and ammunition.

Supply maintenance through BMAs was carried out according to plan and two DIDs were allotted to each beach sub area, while 33 and 38 Port Detachments and another DID were established in 4 L of C Sub Area.

The sites chosen in 101 and 102 beach sub areas were suitable but those for Nos. 2 and 5 DIDs at CREPON were cramped and unsatisfactory. Depot sites in 101 Beach Sub-Area were moved three times, having sustained shell fire, and the majority of the stocks landed into the DIDs in that area were destroyed.

Morale was good from the outset and casualties were light but it was found that there was insufficient labour at all depots. As no Corps FMCs were yet open rations were drawn by first or second line transport direct from BMAs’.

By D+6 approximately two day’s reserve of Compo had been built up by means of a planned rate of one third of a day’s reserve per day from D-day onwards.

An extra fifty tons of shipping space was allotted to S & T on the express coaster which sailed on D+5 and this was used for shipping urgent additional requirements.

The express coaster service was also used for shipping bread for hospital patients daily after D+13.

Owing to the operational situation the supply depots in No. 1 Army roadhead were formed in the area of LA DELIVRANDE by the amalgamation of depots in 101 and 102 BMAs. This was not a satisfactory location but no alteration in site was possible before the capture of CAEN.

No.2 Army roadhead however, formed from 104 BMA was located NORTH, EAST and SOUTH of BAYEUX and proved to be an excellent site for supplies with plenty of room, good natural cover and a suitable traffic circuit.

Base Supply Depots, from which formations were maintained, were established in both roadheads.

By the end of this phase the Field Service Ration had been introduced but it was wholly a preserved ration except for bread which was available in limited quantities from the beginning of July. It had not proved possible to provide frozen meat during this period although steps were taken to provide cold storage at ARROMANCHES in anticipation of it becoming available.

The storm which lasted from 19 to 22 June caused a virtual cessation of unloading but fortunately substantial reserves had already been built up and 8,200,000 rations, representing approximately fifteen days reserves for the force ashore, were in depots in addition to formation holdings on 19 June against the planned figure of 7,200,000.

COAL

Since it was impossible to estimate the precise uses for which coal would be required and in order to have as few different qualities as possible, it was decided to select a coal suitable for several purposes called “GP” or general purpose coal. To facilitate handling all solid fuel was packed in 70 lb. bags.

About 20,000 tons of coal had been packed in the UK and moved to various ports in ENGLAND and WALES ready to be shipped as required and during the period 6 June—25 July approximately 8,000 tons were shipped to the BRITISH sector and taken on charge by 67 and 73 DIDs. As all cargoes shipped were mixed commodities no vessels were loaded with solid fuel only. These DIDs had been given instructions handling coal prior to D-day by working for a period with civilian coal merchants.

TRANSPORT

The planned phasing in of MT units was based on certain known factors such as the minimum tonnage and mileage required to support the assault and the maximum planned capacity of the beaches. There were, in addition, certain forecast factors which were not as certain, such as the build-up of reserves, the progressive build-up of personnel and the forecast of dates for the progress of the operation. In planning these forecasts were treated as firm facts from which the amount of transport required and the dates of landing were calculated.

For the many other imponderables, such as rate of depreciation of MT coys by vehicle casualty, the amount of bridging to be undertaken or the requirements for troop carrying at different stages etc., only estimates could be made. Planning proceeded on that basis and Second Army were to be responsible up to D+17 for the phasing in of such units as they thought necessary for normal Base and L of O transport work, beach work, medical etc. in addition to their own requirements. For tasks which were not a Second Army responsibility e.g. construction at PORT EN BESSIN and motor craft for Tn HQ 21 Army Group nominated a few units for phasing in by Second Army. On completion of Second Army planning HQ 21 Army Group phased in all remaining transport units up to D+60.

The most interesting feature concerning transport was undoubtedly the operation of the 2 1/2 ton amphibious truck known as DUKW. Eleven General Transport Companies were equipped with DUKWS, ten of which were employed exclusively in transportation of stores from coasters and other craft lying off the beaches or from MULBERRY B to dumps ashore.
Part of the remaining company was used to evacuate casualties from the beaches to LSTs while the rest of it was used to bring stores ashore. The companies were an outstanding success and contributed greatly to the maintenance of the forces over the beaches.

During the 24 hours ending 1800 hours D+5 the quantity of stores carried over the three beaches, SWORD, JUNO and GOLD, by amphibians exceeded 10,850 tons. Thirty-six DUKWs were in need of replacement due to damage: of these, about 60 per cent were damaged by mines, 30 per cent by shell fire and 10 per cent by the torpedoing of an LST.

Drivers of amphibious vehicles had great difficulty in recognising and locating ships in the smoke but managed to achieve five turn-rounds between 0500 hours and 2300 hours daily, which was at times more than shore arrangements could handle. DUKW tyres sustained heavy wear and the need for replacements became acute. Otherwise the spares situation was generally good due to the fact that parts that were urgently required were despatched by air.

The work of the DUKW companies and of the Tn units, who were already engaged in the construction of MULBERRY B was considerably assisted by two motor boat companies which arrived during the first two days. One equipped with fast launches was employed in the control of DUKWs while the other, equipped with harbour launches, was employed chiefly in the ferrying of Tn personnel. The motor boat companies had a very low incidence of casualties losing only one launch in the operation.

In addition to stores landed by DUKWs RASC transport was employed both to clear beached craft after they had dried out and, to a lesser extent, the stores brought ashore by Rhino ferries. These were taken to sector stores dumps which were sited just off the beaches and later, to BMA depots when they opened on D+2.

When roadheads were formed the distance from the beaches to depots was too great for DUKWs and it became necessary to establish transshipment areas into which DUKWs delivered their loads. Those units which were to constitute the basic army transport of Second Army remained under control of army and were allocated to lift stores forward from transshipment areas to roadheads. The remaining general transport was placed under HQ L of C who became responsible for movement of stores in rear of the army roadheads.

From the transport point of view this period was characterised by the long hours of the drivers and the bad road conditions which were to have their effect on the vehicles at a later stage.

After D+9 the transport situation changed considerably and there tended to be a surplus of transport for the immediate task, but this reserve was essential in case of a break through. As casualties had been very much lighter than expected the two Ambulance Car Companies in the theatre were only 25 per cent employed during this phase. However, such units as Tipper Companies employed mainly on RE tasks were in great demand and distinguished themselves by their hard work.

POL

It was planned to maintain the forces on the Continent up to D+18 by fuel products packed in UK. The total tonnage involved amounted to 63,000 tons which included the requirements of the RAF. From D+ 18 onwards although the maximum quantity of packed POL would continue to be imported so that the largest number of containers would be available in the theatre, it was proposed to concentrate on importing increased quantities of bulk petrol.

To make the plan effective, small depots were landed in the early stages to receive packed products and to issue them subsequently as required. By D+ 1 there were two Petrol Depots type “C” in each of the beach sub areas. The heavy demand for ammunition as early as D+1 caused a reduction in POL tonnage but even though imports were considerably decreased and 100,000 gallons of petrol and derv were lost by enemy action on D+2 a reserve of POL was rapidly built up because the consumption in the small bridgehead was one third of the planned figure.

By D+6 1,000,000 gallons of POL were stacked in the depots representing a reserve of approximately 2 1/2 days for each vehicle ashore.

While these stocks were accumulating a reconnaissance party had confirmed that PORT EN BESSIN, the small port planned to be used for bulk petrol storage, would be excellent for the purpose.

By D+6 the construction of Tombolas, which were pipelines running some hundreds of yards from the water edge to permit deep draught tankers to discharge off-shore, was put in hand. In spite of bad weather and high seas which retarded the construction work the first tombola was working by 24 June and the first load of bulk petrol was discharged from ship to storage at the pumping rate of 80 tons per hour on 30 June.

By the end of July storage tanks capable of holding 9,800 tons of MT80 and 2,000 tons of aviation spirit had been completed on shore by the Engineers assisted by Pioneers.

When the army roadheads were functioning the packed petrol imports were divided between them most, however, going to No. 2 Army roadhead at BAYEUX as this was to be the first part of the RMA to be developed.

By 5 July, although bulk petrol was beginning to flow steadily into the theatre, packed products were also arriving in large quantities and in order to deal with this tonnage extra petrol units were landed so that by this time there was one petrol depot type “A”, nine type “B” and nineteen type “C” working within the beach-head.

Units to handle bulk fuel were also necessary and the first Mobile Petrol Filling Centre arrived on 30 June and the first Bulk Petrol Transport Company on 5 July.

It was confirmed on 20 June that work in UK on PLUTO which was a scheme for laying cross channel oil pipelines on the ocean bed was so far advanced that the project could be launched on the capture of CHERBOURG, where the first lines were to be connected. In the meantime work had proceeded in laying the pipelines in the RMA.

 

26 July-26 September

 

SUPPLIES

This phase of the operations in North-West EUROPE did not provide any major supply problems of a technical nature. The main problem experienced in common with all planning sections, was the difficulty of forecasting future operational moves due to the constantly changing tactical situation.

The FS bulk ration had almost entirely superseded Compo packs by 21 July and plans for fresh items to take the place of the tinned equivalents were in hand. In order to provide suitable cold storage for imported meat, insulated meat pits and ten-ton portable cold stores were constructed in the neighbourhood of ARROMANCHES.

The shipment of all fresh vegetables was successful, but required a great deal of detailed supervision in DIDs. The baking of bread was somewhat delayed due to the lack of sites with suitable water supplies, and also to delay in shipping the necessary equipment, but by 5 August bread was issued to nearly all troops.

Later it was impossible for bakeries with the armies to keep up with the advance and maintain their output at the same time.

In the case of the L of C, contracts were placed with civilian firms in order to ensure full scale provision of bread for all L of C troops.

The import of supplies was averaging about 2,600 tons per day and by 5 August stocks based on a feeding strength of 700,000 represented some twenty-seven days supply. These stocks were held in RMA EAST and WEST depots which were fifteen to twenty miles apart and were worked independently, each area being controlled initially by a CRASC Supply Units who was responsible for GHQ supply units including BSDs, DIDs, field butcheries and bakeries in his area.

This, however, proved too great a task and on 15 August CRASC 19 Supply Units took over responsibility for the field butcheries, bakeries and two DIDs which dealt exclusively with coal and fresh vegetables. This re-organisation effected a great improvement in both areas.

Early in August it was decided when making the bids for the period D+94 to D+103 that the tactical situation and the stocks on the ground justified the introduction of commodity loading in accordance with the original maintenance plan.

However, the greatly changed situation as the time for receipt of these supplies approached had strained the transport system to its limit. It was hoped, however, to relieve this by shipping the intake of maintenance through Channel ports and a last minute attempt was therefore made, in vain, to revert to balanced ration loadings for this period.

In point of fact failure to revert to the balanced ration system was of little on sequence as when the armies began their advance all drawing of fresh rations practically ceased, the major issues being Compo, except for captured stocks. A considerable quantity of the latter was available.

At OSS in HOLLAND 11,000,000 pounds of frozen beef and 850 tons of tinned meat were uncovered. 550 tons of meat were also found in the area of BRUSSELS, in addition to a large number of miscellaneous items which Were used in substitution for items in the BRITISH scale.

For five days Second Army subsisted on captured stocks without having to touch first, second or third line reserve holdings.

In the latter half of September all units in FRANCE received full daily issues of frozen meat from cold storage facilities at ROUEN and AMIENS.

Demands from armies for roadhead replenishments were based on a seven days cycle, armies submitting detailed breakdown demands with priorities two days before each period.

The aim was to deliver six days balanced rations and one days balancing items. This scheme was slow in getting into operation, mainly due to rail transport difficulties and the impossibility of reconciling receipts with despatches.

The problem of distribution began to be easier from 9 September when DIEPPE opened, becoming available as a base for First Canadian Army and a modest rail lift became operative to the SEINE railheads. During the critical period in the first fortnight of September, 600 tons were flown to the BRUSSELS area from UK for Second Army.

TRANSPORT

The build-up in the bridgehead had increased to such an extent since D-day that due to congestion on the roads certain transport units had been phased back. Early in August, however, these were again called forward in anticipation of a large scale advance.

On 6 August in response to a request from HQ 21 Army Group one three-ton and one six-ton GT Coy were loaned to the US armies for an agreed period of eight days.

Despite the fact that a third GT Coy was loaned, it was not possible to release these units until 4 September when the transport crisis on the BRITISH L of C was at its height. A DUKW company was also loaned to the AMERICANS for use on the UTAH beaches for six weeks.

From 22 August onwards more and more transport had to be provided to enable the armies to stock their roadheads. Although it had been originally planned to establish roadheads at distances of fifty to one hundred miles apart and to stock them up to maximum of five days holdings of all stores, this system had to be modified owing to the extreme rapidity of the advance. First Canadian Army economised in transport by setting up an advance section of No. 3 Roadhead, thirty miles further on near BOUGTHEROLDE.

As transport became available stocks in No. 3 Roadhead at LISIEUX were moved forward and this advance section became the base of the First Canadian Army up to the line of the SOMME. With the opening of DIEPPE the transport allotted to First Canadian Army from HQ 21 Army Group resources amounted to eight three-ton companies.

Second Army formed temporary “cushions”, the first of which was established South-West of FALAISE and preceded the opening of No. 4 Roadhead EAST of RUGLES.

On 19 August prior to the stocking of No. l Cushion, Second Army had six equivalent three-ton GT coys from GHQ resources under their command.

By 26 August this number had increase to fourteen and on 2 September, exclusive of two platoons of army tank transporters converted for load carrying, thirty-nine equivalent three-ten GT coys were under their command.

By the middle of September the BRITISH L of C had lengthened to three hundred miles, almost double the distance on which the allotment of transport to 21 Army Group had been calculated. Until the development of rail and port facilities, therefore, the road maintenance lift had to be increased by every possible means.

The decision to cut imports into the RMA to seven thousand tons per day already mentioned in para 5(b) released eight DUKW companies for conversion into normal GT coys and also a number of GT coys empoyed on beach clearance. At the end of September only three DUKVV companies remained as such, of which one was on loan to US Army.

In August Second Army followed the example of First Canadian Army and by welding on to each trailer at base and sides of airfield track converted a company of forty-ton tank transporters into load carriers. First Canadian Army had previously converted one platoon.

These modified transporters could lift sixteen and a half tons of supplies, thirty-six tons of ammunition, ten tons of POL or five hundred jerrycans, which meant a very considerable lift for a three platoon company.

An extra. lift of between five and six hundred to11s was added to the pool by bringing five GT coys up to their full WE and by the issue surplus to VVE, of an additional thirty three-ton reserve vehicles to each of four GT coys. In addition, one hundred and fifty-four 800 gallon tankers were issued early in September to supplement the seven bulk petrol transport companies employed on forward maintenance.

On 16 September eight US truck companies commenced to run from BAYEUX to BRUSSELS delivering five hundred tons of petrol per day.

On 20 September they were employed on the maintenance of the two US airborne divisions which took part in operation MARKET GARDEN.

Further assistance came from the release of AA RASC transport platoons and six platoons of twenty-nine and three platoons of twenty-two three-ton vehicles were formed from first line AA transport. Two ten-ton GT coys were further equipped with five-ton trailers.

The decision by Second Army to ground certain formations in the advance released considerable amount of first and second line transport for local work, thus enabling GT coys to continue in the maintenance lifts.

In mid-September War Office agreed to loan an additional seventeen GT coys to 21 Army Group. five arrived before the end of this phase, the remaining twelve were expected to arrive preloaded with supplies or petrol before 3 October.

The ever increasing transport required for Civil Affairs was an added handicap to the maintenance of the armies. Between 26 August and 6 September five thousand tons of food and medical supplies from Civil Affairs depots at BUSSY and LUC-SUR--MER were transported to PARIS.

On 9 September First Canadian Army formed No. 5 Roadhead SOUTH of ABBEVILLE at the same time as DIEPPE was opened. This roadhead and the opening of the SEINE railheads on 13 September, coupled with an increased allotment of two additional GT coys on 16 September allowed First Canadian Army to maintain itself to the DUTCH frontier, and to clear approximately three thousand tons per day from DIEPPE.

On 6 September Second Army began stocking X0. 6 Army Roadhead in the area of GRAMMONT. When trains began to run in limited numbers from the RMA the dualproblem arose of continually balancing the rail capacities on either side of the SEINE and lifting by road the balance of the six thousand tons per day required by that army for its maintenance and stocks. HQ 21 Army Group, therefore, assumed responsibility for the control of all transport and set up the organisation entitled TRANCO at AMIENS on 19 September.

By 25 September orders had been issued for the regrouping of the GT coys in the DOULLENS and ELBEUF areas NORTH and SOUTH of the SEINE.

In each of these areas two CSRASC each commanding a group of companies were placed. Of these one was responsible for road patrol and the organisation of staging camps, while the other called “Control” was responsible for reporting daily, by wireless, availability of transport in the area and movement of all maintenance convoys through the report centre established on the main “up” and “down” routes. Control CSRASC also operated at the RMA, at No. 6 Army Roadhead, and at DIEPPE.

The co-ordination of transport allocation was then exercised by TRANCO, based on “Q” priorities given to Second Army demands. A loading bill was sent out daily by wireless or telephone forty-eight hours in advance to controlling HQ.

VEHICLE MAINTENANCE

During this intense period of activity the maintenance of vehicles inevitably had to be reduced, but partly due to the majority of vehicles being new no serious ill effects ensued.

A major fault occurred in the engines of K-5 4 X 4, three-ton Austins, 1,400 of which, as well as all the replacement engines, were found to be defective and to have piston trouble.

AIR FREIGHT

When BRUSSELS and ANTWERP were reached, maintenance by air became imperative and a HQ CRASC transport column trained in air freight organisation was transferred from the RBLA and placed under command of Second Army.

By 13 September this HQ with two DIDs had handled 6,352 tons of stores. The tonnages of air freight increased throughout the month, during which an average of between four hundred and five hundred tons a day was achieved.

Early in September bulk petrol was delivered to LILLE by means of long range tanks of Liberator aircraft but this experiment was abandoned as it was wasteful both in petrol and aircraft.

PETROL

At the beginning of this period imports of POL were averaging 4,500 tons per day of which fifty per cent was in bulk against an average daily consumption of POL products of 2,000 tons per day. The restriction of movement in the bridgehead reduced petrol consumption to a minimum and by 5 August the stock of MT 80 was 66,000 tons representing thirty-three days stock. All petrol units that were required for the bridgehead had arrived by 5 August but eight bulk petrol transport companies were phased in by 25 August in anticipation of the advance across the SEINE.

As First Canadian Army and Second Army were based on RMA EAST and RMA WEST respectively all issues to armies were by pack, but at the same time L of C units were commencing to receive their petrol in bulk which released jerricans for the impending advance.

During August the physical distribution of petrol to the armies caused no difficulty until the crossing of the SEINE. Meanwhile, the intake of bulk petrol through PORT EN BESSIN was approximately 2,300 tons per day with a similar amount arriving in pack.

The consumption during the second half of August had doubled and stabilised at approximately 4,000 tons of all products per day. Forward distribution was effected during the early stage of the advance by transporting packed POL stores by road from the RMA to No. 3 and No. 4 Roadheads.

In order to increase the bulk petrol lift, Q(AE) authorised the issue of seventy, and in early September a further eighty-four, additional 800 gallon tankers to the bulk petrol companies to be held surplus to establishment. Between 5-10 September a total of 2,308 tons of packed MT 80 was delivered by air to the BRUSSELS area.

On 9 September rail service from the RMA to the SEINE was opened and the first 750 ton train was despatched to BERNAY on the same day.

The progress of the pipeline continued and on 16 September bulk petrol lorries started loading at BRIONNE for the army filling areas which were at this time at NEUFCHATEL and GRANDE VILLIERS.

By 18 September the pipeline was extended to the PETIT COURONNE installations at ROUEN where 160,000 empty jerrycans had been collected. Simultaneously a filling area under GHQ, control was opened at DARNETAL to utilise the very large number of empty jerricans left in the area.

DARNETAL besides being the pipehead NORTH of the SEINE also became the rail tank car filling point as the rail was developed.

The first line of PLUTO had been laid from the ISLE OF WIGHT to CHERBOURG. On 13 August pumping of water commenced and by 24 August Water pumping tests on the second line were proceeding at a rate equal to approximately 145 tons per day.

During September approximately 4,000 tons per day was required for the force, and although 2,000 tons per day could be accepted in bulk at PORT EN BESSIN, the balance was required to be stored at an advanced port in order to economise in transport. OSTEND, liberated on 9 September, was the port chosen and the first tankers were discharged there on 29 September.

Stocks of packed products in the UK were now so limited that imports of packed POL had to be reduced in October to the production rate of 350 tons per day.
