Loss of the HMS Birkenhead

"Vintage engraving from 1878 showing the loss of the Birkenhead. The Birkenhead was an iron paddle steamer of 1400 tons, and was launched in December 1845. On 26 February 1852, while transporting troops to Algoa Bay, she was wrecked at Danger Point near Gansbaai on the outskirts of Cape Town, South Africa. There were not enough serviceable lifeboats for all the passengers, and the soldiers famously stood firm, thereby allowing the women and children to board the boats safely. Only 193 of the 643 people on board survived."
