British 4th Armored Brigade crossed the desert between Halfaya and Sidi Omar in Egypt in an attempt to cut the road to Tobruk, Libya. To counter the British naval bombardment, Italian submarine Neghelli attacked British cruiser HMS Coventry 40 miles northeast of Sidi Barrani, Egypt at 2042 hours, nearly blowing off her bow; she was able to sail under her own power to Alexandria, Egypt for repairs.
