On 13 June 1944, most of the 49th Division, after just over two years of training, landed in Normandy as part of Operation Overlord. The division arrived too late to take part in the Battle of Villers-Bocage, where the veteran 7th Armoured Division suffered a serious setback, but was involved in the numerous attempts to capture the city of Caen. The division, after landing, was only involved in relatively small-scale skirmishes, most notably on 16 June around Tilly-sur-Seulles, where the 6th Battalion, Duke of Wellington's Regiment, of the 147th Brigade, suffered some 230 casualties − 30% of its war establishment strength − in a two-day battle whilst attempting to capture Le Parc de Boislonde. The position was eventually taken by the 7th Battalion, Dukes, under Lieutenant Colonel John Wileey. The 49th's first major action as a division came during Operation Martlet, the first phase of Operation Epsom, the British attempt to capture Caen. Although Lieutenant General Sir Richard O'Connor's VIII Corps made the main effort, XXX Corps, with the 49th Division under control, was to protect VIII Corps' right flank by seizing the Rauray ridge.
