The attack on the chief coastal batteries which the R.A.F. Bomber Command launched half an hour before midnight on the night of 5-6 June was, in terms of weight of bombs, the heaviest blow the Command had ever struck. It went on until 5:15 a.m., and during this period 5268 tons of bombs were dropped and the Command made 1136 individual sorties. The targets, from west to east, were batteries at La Pernelle, Crisbecq, St. Martin de Varreville, Maisy, St. Pierre du Mont, Longues, Mont Fleury, Ouistreham, Merville/Franceville and Houlgate.
