On 30 May Rommel resumed the offensive, and on 1 June, Rommel accepted the surrender of some 3,000 Commonwealth soldiers. On 6 June, Rommel's forces assaulted the Free French strongpoint in the Battle of Bir Hakeim, but the defenders continued to thwart the attack until finally evacuating on 10 June. Rommel then shifted his attack north; threatened with being completely cut off, the British began a retreat eastward toward Egypt on 14 June, the so-called "Gazala Gallop".
