Churchill was determined to be actively involved in the Normandy invasion and hoped to cross the Channel on D-Day itself (6 June 1944) or at least on D-Day+1. His desire caused unnecessary consternation at SHAEF until he was effectively vetoed by the King who told Churchill that, as head of all three services, he (the King) ought to go too. Churchill expected an Allied death toll of 20,000 on D-Day but he was proven to be pessimistic because less than 8,000 died in the whole of June.
The Allied forces landed on Normandy beaches, establishing five beachheads in Normandy. It was the largest seaborne invasion in history. The operation began the liberation of German-occupied France (and later western Europe) and laid the foundations of the Allied victory on the Western Front.
On 14 June 1944, Charles left Britain for France for what was supposed to be a one-day trip. Despite an agreement that he would take only two staff, he was accompanied by a large entourage with extensive luggage, and although many rural Normans remained mistrustful of him, he was warmly greeted by the inhabitants of the towns he visited, such as the badly damaged Isigny.
The United States also invited a smaller group of countries to send experts to a preliminary conference in Atlantic City, New Jersey, to develop draft proposals for the Bretton Woods conference. The Atlantic City conference was held from June 15–30, 1944.
The Battle of Kohima was the turning point of the Japanese U-Go offensive into India in 1944 during the Second World War. The battle was fought in three stages from 4 April to 22 June 1944 around the town of Kohima, the capital of Nagaland in northeast India. From 3 to 16 April, the Japanese attempted to capture Kohima ridge, a feature which dominated the road by which the besieged British and Indian troops. From 18 April to 13 May, British and Indian reinforcements counter-attacked to drive the Japanese from the positions they had captured. The Japanese abandoned the ridge at this point but continued to block the Kohima–Imphal road. From 16 May to 22 June, the British and Indian troops pursued the retreating Japanese and reopened the road. The battle ended on 22 June when British and Indian troops from Kohima and Imphal met at Milestone 109, ending the Siege of Imphal.
