I Corps, striking south out of the Orne bridgehead, was halted by the 21st Panzer Division and the attack by XXX Corps west of Caen was stopped in front of Tilly-sur-Seulles by the "Panzer-Lehr-Division". To force "Panzer-Lehr" to withdraw or surrender and to keep operations fluid, part of the 7th Armoured Division pushed through a gap in the German front line near Caumont and captured Villers-Bocage. The Battle of Villers-Bocage led to the vanguard of the 7th Armoured Division being ambushed and withdrawing from the town but by 17 June, "Panzer Lehr" had also been forced back and XXX Corps had taken Tilly-sur-Seulles.
