  • 47 German dive bombers sank British gunboat HMS Ladybird in Tobruk harbor, Libya with two bomb hits, killing 4 and wounding 14; Ladybird's gunners damaged two German dive bombers in return. Although she settled in 10 feet of water, her 6-inch gun was still above water, and thus she would remain useful as a stationary anti-aircraft gun platform while repairs were being done. Admiral Andrew Cunningham sent the message to her commanding officer "Great fighting finish worthy of highest ideals and tradition of the Navy and an inspiration for all who fight on the seas." ww2dbase [Siege of Tobruk | CPC]
