13 September – On this day

Italian forces begin a cautious offensive from Libya into Egypt.They have five divisions in the attack with another eight in rear areas in Libya. Marshal Graziani  is in command. The British Western Desert Force of two divisions is led by General O’Connor. On the first day the Italians occupy Sollum as the British pull back.

During the months since the Italian declaration of war there have been no actions of any size, but the Italian numerical superiority has been morally undermined by much offensive patrolling by the British forces. These harassing tactics are now employed to good effect against the Italian offensive.
