The Axis offensive on the Libyan-Egyptian border resumed despite the lack of progress at Tobruk, Libya; German troops engaged British patrols near Fort Capuzzo. The 2 remaining Hurricane fighters in Tobruk were withdrawn to Egypt to join the mere 13 Hurricane fighters there, leaving Tobruk with only Lysander aircraft to perform artillery spotting duties and no aircraft capable of air defense. Out at sea, British submarine HMS Upholder sank Italian ship Antonietta Lauro off the Tunisian island of Kerkenah.
