The Germans attacked Bir Hakeim on May 26. Over the next two weeks, the Luftwaffe flew 1,400 sorties against the defenses, whilst 4 German/Italian divisions attacked. On June 2, 3, and 5, the German forces requested that Koenig surrender, he refused and launched counterattacks with his Bren gun carriersss. Despite the explosion of the defence's ammo dump, the French continued to fight using ammo brought in by British armored cars during the night. Meanwhile, the Royal Air Force dropped water and other supplies.
