6 June 1944 - 25 July 1944

 

The main task which devolved on the Transportation Service was to discharge and clear in conjunction with S & T the planned tonnage of 900,796 tons of stores in addition to hundreds of vehicles over the beaches or through ports, during the months of June and July.

As stated elsewhere, due to bad weather and difficulties in establishing the Ferry Craft Control, this figure was not quite reached. As it was, over 750,000 tons were brought ashore without the aid of a proper port.

Unlike other Services, Transportation normally controls all Tn troops on the ground direct from HQ 21 Army Group. This course was not possible at the beginning of operation OVERLORD. During this first phase, therefore, all Tn activities were controlled by an advanced HQ of Tn 21 Army Group which was placed first under command of HQ 11 L of C Area and then under command of HQ L of C until the arrival of HQ 21 Army Group in the theatre.

It may be said that from a Tn point of view, this operation was largely successful, but the complexities of the problems and all the technical planning and execution by the Tn Service, in conjunction with the Movements Staff of HQ 21 Army Group are too great to enable a complete picture to be given in the brief space available.

During the first few days the responsibility for discharging ships was that of the beach group commanders who were assisted by their port operating staffs. In addition the craft ferry service run by the Navy and the DUKW ferries organised by the RASC were controlled through the same channels.

Initial difficulties was experienced in evolving a proper ferry organisation and cases of serious delays to ships occurred. As the weeks passed the anchorages became more centralised, control became easier and a definite split in functions was made so that MT was passed over GOLD beaches and stores were centred on JUNO.

As the operation proceeded, the Port Operating Groups took over complete responsibility for the discharge of ships and for controlling the unloading of craft when beached. An improved turn round of ferry craft was already being obtained in the first week of July by centralising control of ferry services. The phasing in of Port Operating Companies kept pace with the tasks that they were set.

Port Construction and Repair units were landed at the same time as port operating units to repair the small ports of PORT-EN-BESSIN, COURSEULLES and OUISTREHAM. A special port construction task force was also landed at the same time to carry out the construction of MULBERRY B. An account of this will be found at this image”.

Small coasters were unloaded in PORT-EN-BESSIN and preloaded barges discharged there and at COURSEULLES. OUISTREHAM and CAEN could not be developed until cleared of the enemy and out of range of gunfire.

For some time after the capture of CAEN, the coastal defences at CABOURG continued to dominate the approaches to OUISTREHAM. The port of CAEN is reached by the OUISTREHAM-CAEN canal. The domination of OUISTREHAM therefore delayed the opening of CAEN.

The IWT organisation which did yeoman service with its tugs, PBRs and Rhinos loaded with MT, was faced with great difficulties during the stormy weather which prevailed during most of the first three weeks of the operation. IWT workshops were quickly set up and repairs put in hand, but the fact is that during bad weather the Rhinos were not really suitable for their task, being under-powered. They functioned more satisfactorily during the better weather later, but generally proved a continuous source of trouble.

The railway personnel were phased in after the ports and IWT personnel, but apart from reconstructing minor lines, repairing wagons and developing one or two rail served depots, it was impossible to do much during this phase. The railway signals branch of Tn began to function during this period, but their work can better be discussed later.

By the end of this phase, 16,000 tons of Tn stores had been landed and two Transportation Stores Depots set up.

In addition a number of small stores dumps were established at important centres of Tn activity. Without going into details of all the various types of equipment used in this operation by Tn, it can be stated that generally the equipment provided was found to be adequate in spite of the difficulties of weather which were encountered. It should be borne in mind, however, that every combined operation must be regarded as an individual problem and treated as such, and no hard and fast conclusion as to the suitability of equipment for all combined operations can be drawn from the experience gained in OVERLORD.

 

26 July-26 September

 

Until the middle of August there was no great change in the activities of the Tn Service as unloading continued across the beaches and through MULBERRY and the small ports in the beach head in preparation for the expected advance NORTH.

But when the break-through to the SEINE took place, followed by the advance through FRANCE and BELGIUM into HOLLAND, Tn were faced with two big problems.

  • Firstly, a long rail L of C from the RMA across the SEINE forward into HOLLAND had to be organised, and
  • Secondly, in order to shorten the L of C and bring supplies by a shorter route through ports that would be able to operate right through the Winter, the Channel ports had to be opened.By the end of September both these tasks had been successfully tackled and a rail L of C existed from the RMA right through to EINDHOVEN.

The port of DIEPPE was open and the ports of OSTEND, BOULOGNE and ANTWERP were being made ready to accept shipping, although the use of ANTWERP depended on clearing the SCHELDT estuary of hostile elements.

The development of the rail L of C focused from the very start on the development of CAEN which had to become the main traffic and locomotive centre in spite of the damage that had been sustained there.

Energetic action had to be taken to repair yards, sidings, workshops and locomotive sheds, communications and signals. This was followed by the opening of the railway line to SERQUIGNY and to the SEINE and later railway construction troops were spread out all along the line to SERQUEUX and forward into BELGIUM. For this four railway construction and maintenance groups and fourteen railway construction companies had been brought over into the beach-head in readiness.

Throughout North-East FRANCE bomb damage at rail centres had been extensive and had been combined with serious demolition SOUTH of the SEINE, although NORTH of the river the demolitions were less widespread. A large number of bridges were down in the BRITISH zone in FRANCE and damage to installations and track was heavy.

The problem, from a 21 Army Group point of view, was a dual one. In the first place the most profitable route for repair had to be selected and in the second place the actual work of repair had to be organised utilising BRITISH resources and manpower and whatever assistance could be obtained from the FRENCH and BELGIANS.

The first part of the problem involved the use of a very wide range reconnaissance which was found extremely difficult to control and coordinate owing to the extremely bad communications and also to the acute shortage of transport.

It was decided, owing to the destruction of all bridges across the SEINE, to establish railheads SOUTH of the river with a road link across the river and rail tails somewhere NORTH of the river. This system was a makeshift to close the gap until the SEINE bridge at LE MANOIR was constructed on 22 September.

This bridge although 520 ft long was successfully completed in fourteen days. Two main bridges were also down across the SOMME, but it was found possible to bypass this damage by a diversion at DOULLENS.

Apart from this it was possible to get the L of C completed right through to BRUSSELS with the exception of a major bridge at HAL which was reconstructed by the BELGIANS.

In spite of the efforts of the railway operating organisation it was not until the end of September that the railways of FRANCE and BELGIUM began to show signs of settling down to provide any kind of reliable service. Communications were bad, particularly in the AMIENS arrondissement but after very close collaboration with the SNCF and the SNCB, the main trunk links and control circuits were nearly completed by the railway signals staff by the end of September.

The operating service was short of stock and locomotives due to an inadequate allocation of the engines being imported on allied account through CHERBOURG, but this problem had been gradually solved by the end of September.

The opening of the DIEPPE train ferry on 29 September finally overcame the problem of locomotive shortage, since locomotives for BRITISH use could thereafter be delivered direct to the BRITISH sector in accordance with a prearranged programme.

Amongst the most awkward of problems was that of coal, all of which was being imported from the UK principally via CAEN and CHERBOURG, and the coal traffic required for moving trains NORTH of the SEINE was taking up paths across the SEINE which could ill be spared.

Every effort was being made towards the end of September to arrange for coal to be provided from FRENCH sources in the mining area of the NORTH.

To tackle the problem of organising a rail L of C which was operated entirely by BRITISH troops in some sectors, by FRENCH and BRITISH in another and entirely by FRENCH and BELGIAN personnel elsewhere, great flexibility of organisation was essential.

It was found necessary by mid-September to drop the standard railway operating group and railway unit organisation in the area SOUTH of the SEINE and to set up a divisional superintendent’s office at CAEN.

At the same time the head of the railway branch left BAYEUX, where HQ 21 Army Group Rear remained, and went forward to ROUEN Where it could maintain some contact with TRANCO.

ROUEN had been selected as the base from which to send out the necessary railway construction reconnaissances and it was also suitable for the central control of railway operating.

Nevertheless it was soon found that it was necessary to have a railway operating headquarters further forward and a group HQ moved to AMIENS. As soon as BRUSSELS fell a railway staff was set up alongside the SNCB in that city.

In the area SOUTH of the SEINE the actual operating itself was complicated and difficult as it was a very bad section of line to work, so that at times it was not possible to attain the agreed programme.

The following are some of the particular difficulties encountered;

  • first, a spate of rail breaks between CAEN and MEZIDON which was due to the effects of shelling
  • second, accentuation of traffic-working difficulties by engine failures and hot axle boxes, particularly on the US double-headed through trains
  • third, there was congestion in the CAEN yard and in the RMA area due to limited siding capacity, loading points and depots
  • fourth, there was a shortage of engine power due particularly to insufficient numbers of BRITISH locomotives and insufficient shed facilities to handle the locomotives at CAEN.

NORTH of the SEINE, however, apart from the problems of water supply and repair of lines, the greatest difficulty encountered was that of re-organising the railway operating service in collaboration with the FRENCH and later with the BELGIANS.

Though the railway operating units could be used for this type of work they had been designed to operate railways rather than to assist others to do so, and their organisation was not altogether suitable for the latter task.

The second half of the problem on the Tn side was to develop the Channel ports as quickly as possible and thus relieve the strain on the L of C. It was not possible to open up CAEN as a port until the end of August, but other facilities were found to be adequate and, as a precaution, work continued on the winterisation of MULBERRY.

Preparations were made well in advance for opening each of the ports as they were captured. Reconnaissance parties were sent forward together with Royal Naval parties, the port commandant and sub-area representatives. They took with them a basic key plan to work from and were ordered to produce a final plan for the complete development of each port. For this Work the port construction and repair groups and port operating groups were utilised.

Representatives of 21 Army Group kept in closest contact with them in order to make the maximum possible use of facilities and resources at the disposal of 21 Army Group and to ensure that the planning of shipping and the shipping of stores could be modified to conform to the actual situation in each of the ports as they were captured.

The port of DIEPPE was captured on 2 September, by 7 September ships were being discharged there and by the end of the month a maximum of 7,200 tons in one day was being discharged and cleared by rail and road. The capture of BOULOGNE and OSTEND did not however provide two additional ports immediately as they were both in a very damaged state. All three ports were heavily demolished, blocked and mined, but in many cases demolitions were inexpertly and incompletely executed.

The factors which were most important in preventing these ports from opening quickly were mine clearance and the removal of block ships in the entrance. ANTWERP was taken by the end of the month but could not be operated because the SCHELDT was heavily mined and the GERMANS still occupied the river approaches.

The shortage of MT experienced by all in this phase had a very direct bearing on the administration and functioning of Tn units. With the advance most of the units had to change their location at least once if not twice and the movement of all these units with their impedimenta produced problems of the greatest complexity.

Not one of the Tn units was fully mobile and about 550 lorry and 100 transporter lifts additional to unit transport were required to move Tn units and equipment to the places where they were required to work.

Tn units could not, therefore, be moved with complete flexibility from place to place and in some cases were not able to get down to their Work as quickly as was desirable.

With the extension of the L of C from ARROMANCHES to EINDHOVEN the Tn Service became extremely difficult to control largely due to difficulties of communication.

On the move of HQ, 21 Army Group to BRUSSELS the DDTn (Ports) became directly responsible for the development of OSTEND and ANTWERP and through HQ 11 L of C Area for DIEPPE, LE TREPORT, BOULOGNE and CALAIS while MULBERRY B, PORT EN BESSIN, CAEN and OUISTREHAM continued to be developed under the supervision of HQ 12 L of C area.

The railways and stores organisations also moved to BRUSSELS leaving a divisional area organisation at AMIENS and a railway operating group at CAEN. The Tn Service was thus suitably disposed to prepare the build-up during the winter for the attack on GERMANY.
