3 of 8 The Graf Spee was hunting merchant shipping in the Atlantic in December 1939, when it was engaged by British and New Zealand warships in the Battle of the River Plate.

4 of 8 After taking 20 hits, the captain sought refuge in the Uruguayan port of Montevideo. Her sailors were glad to be out of the reach of Allied guns.

5 of 8 Under British pressure, Uruguay asked the Graf Spee to leave. Her captain scuttled her in the bay, to keep her out of Allied hands.

6 of 8 The battleship sank in waters less than 8 metres deep, on 17 December - Captain Hans Langsdorff committed suicide three days later.

7 of 8 The survivors from the ship were remembered in a series of photos either taken or collected by sailor Friedrich Adolphe.

8 of 8 Friedrich Adolphe himself is identified in this photo, taken after the ship's survivors were rescued.
