The document summarizes the engagement between the Australian cruiser HMAS Sydney II and the German raider HSK Kormoran off the coast of Western Australia in November 1941. Sydney was en route from Indonesia to Fremantle when it made contact with Kormoran. Kormoran was disguised as an allied merchant ship but heavily armed for close combat, while Sydney was equipped for long range combat. The two ships closed to within a nautical mile before Kormoran opened fire, sinking both vessels in the ensuing battle.
