The six year old British-built 34-gun Peruvian frigate Callao capsized and sank in the harbor at San Lorenzo, Peru while being moved into a dry dock. The warship itself had large numbers of guests aboard and the Peruvian president and other dignitaries were watching from other vessels. Around 100 people died and 88 were injured. The Callao was raised in 1863, restored to its old name Apurimac, and resumed its career. (By John Osborne)
