Operation Compass. British 7th Armored Brigade moves through the desert to outflank Sollum and cut the road to Bardia, across the border in Libya. Sollum is strategically important, having a small bay and jetty which will allow Royal Navy to bring supplies to O’Connor’s forces. Italian prisoners of war start arriving by truck back at the British headquarters at Mersa Matruh and 650 are evacuated to Alexandria by destroyers HMS Janus and Juno. Aircraft from British aircraft carrier HMS Illustrious attack Italian forward supply base at Bardia, Libya, bombing barges in the harbour.
