German and Italian troops and tanks, with Rommel personally taking charge, break through the British perimeter and overrun 150th Brigade “box” at Sidi Muftah in bitter hand-to-hand fighting. A relief column sent by the British along the Trigh Capuzzo and Trigh el Abd desert tracks is stopped by Rommel's anti-tank screen. 3000 British troops surrender, after their commander Brigadier Clive Haydon is killed by shellfire. This allows Rommel to secure supply lines North and South of the British who have been harrying his trucks with artillery fire. Capture of this “box” also completes the encirclement of the French in the fort at Bir Hacheim.
