A photograph of the complement of HMA Submarine AE2, the RAN vessel behind one of the least known naval stories from the Gallipoli campaign of World War I. AE2 was the first submarine to penetrate the Dardanelles Strait and from 25 April to 30 April 1915, played a hectic game of cat and mouse with Turkish forces, causing confusion and raising alarm that delayed Turkish reinforcements across the straits.
