The regiment were in the final stages before crossing to North-West Europe after D-Day. The landings had already happened on 6 June 1944, but 13 Medium Regiment had not yet gone across. They were still in England, preparing men, vehicles, guns, and equipment for the move overseas.
On 9 June, the regiment moved to Five Oaks Camp near Horsham, described as a concentration area. In this context, that means a gathering point where units were assembled, checked, equipped, and prepared before moving on. The diary notes that the regiment was brought up to full strength in vehicles and equipment, which means they were getting ready for active service abroad.
A key job mentioned twice is waterproofing. Before driving off landing craft into the coastal surf of Normandy, every single truck, Matador tractor, and gun had to be slathered in thick waterproof grease (asbestos compound), with rubber hoses fitted to high exhaust pipes. If seawater got into the engine, the vehicle was dead in the water.
By 18–19 June, the advance party and then the main body moved to the Marshalling Area at Wanstead Flats in London. A marshalling area was the final holding area before embarkation. The diary’s phrase “a most unpleasant camp” gives a small but very human glimpse of conditions before they sailed. Thousands of men were crammed into canvas tent cities surrounded by barbed wire so no secrets about the invasion could leak out.
The most dramatic part is 22 June. The drivers and vehicles were loading at Victoria Docks when the ship carrying 89 Battery’s vehicles narrowly escaped damage from a near miss by a pilotless bomb. This almost certainly refers to the German V-1 flying bombs, which began falling on London in June 1944. So even before the regiment reached the continent, they were already in danger from enemy attack.
Eyewitness Memory (IWM Sound Archive, Cat. 12497):
Veteran William O’Sullivan recalled this exact moment in an Imperial War Museum interview. As the Doodlebugs started coming down around Victoria Docks, the sudden panic caused the troops on board to rush to one side of the vessel for cover, almost tipping the ship over before they had even set sail.
