The first elements arrived at Msus late on the afternoon of 4 February and cleared the local garrison. During the following night and day the advance continued and the British artillery and infantry were in position across the coast road by 4:00 p.m. on 5 February. The head of the retreating Italian column arrived 30 minutes later. The Italians were stunned to find the British force blocking them at Beda Fomm, whose strength they greatly overestimated. With the Australians in pursuit, a desperate battle ensued, in which newly arrived Fiat M13/40 medium tank battalions were thrown against the British positions, at great loss. In the afternoon of 6 February, the 7th Armoured Division tanks arrived and harassed the Italian eastern flank.
