Axis turn of July 15tht, 1943
D-Day in France! In a huge aeronaval assault, the Allies landed 10 corps in France (including 4 paratrooper corps), around 2/3 of them British. The attack overwhelmed the defenders, some of them equipped with outdated equipment. Three coastal divisions were pulverised, the 7th, 19th and 20th. They were defending Calais and its left flank as well as the Southern approach to Le Havre. The Calais garrison managed to hold for a few short days but had to cave-in eventually. With this result, most of the coast from the Belgian border to Normandy is in Allied hands, except for Dunkerque and Le Havre that are been besieged but not expected to last long. Rouen is in firmly American hand and Lille has been occupied by some British paratroopers than then left to move North. Some fighting is still been done all around the city.
In a panic, OKW ordered General Guderian back from the East with three Panzer or PanzerGrenadier corps. Those corps are battle hardened units from the recent battles around Kursk, but only had a few weeks of recovery and are not in top fighting shape. Hopefully, the supply problems for the Allies might compensate that on the battlefield.
Italy also sent help in the form of two infantry corps after OKW insisted much and agreed to, maybe, review upward the transfer of oil to Italy after the crisis is solved. Originally OKW insisted for two armored corps from Italy, but that was very explicitly refused.
