Sidi Barrani
Despite prodding from Mussolini, the Italians dug in around Sidi Barrani and Sofafi, about west of the British defences at Mersa Matruh. The British anticipated that the Italian advance would stop at Sidi Barrani and Sofafi and began to observe the positions. British naval and air operations continued to harass the Italian army as the 7th Armoured Division prepared to confront an advance on Matruh.
