D-Day Memories
Captain Robert Worth landed on Sword Beach

When the break-out approached, we had moved up to the outskirts of Caen to build additional jetties in Caen docks. We were stationed just to the north-west of Caen and all available heavy and medium guns had been drawn up in an arc to be ready for the advance over the open and higher country to the south east of Caen.
The guns had ample dumps of ammunition behind them. At mid-day, with a clear blue sky, we heard bombs start to come down and saw three Flying Fortresses start to plaster our own ammo dumps - we later heard from the RAF that a Mosquito was up there too and tried to signal the Fortresses that they were bombing way off target, but with no effect. He shot one down, but by then the damage had been done. The dumps continued to explode for at least 24 hours.
Therefore the break-out was delayed to allow for the dumps to be built up again.
The result was that the closure of the trap at Falaise was not total and some German divisions escaped although badly mauled. All this I can vouch for, but later I learned that the one of the divisions which happened to be re-equipping in the Arnhem area at the time of Market Garden was one of those which had escaped. It thus seems to me probable that but for the Flying Fortresses and their 'friendly fire' Arnhem might have been a success and we would have been through to Berlin before Christmas, long before the Russians, with a resulting profound effect on post-war state of affairs in Europe. Perhaps for want of a horse-shoe the battle was lost.
