The Battle of Jutland (31 May - 1 June 1916) was the largest naval battle of the First World War. The Germans damaged Beatty’s flagship, HMS Lion, and sank HMS Indefatigable and HMS Queen Mary, both of which blew up when German shells hit their ammunition magazines. All 57 officers and 960 seamen of the crew of the Indefatigable were lost – including Midshipmap William Llewelyn Griffith (Ha. 1905-10), aged 18.
