Worn by Rear Admiral John Collings Taswell Glossop, Royal Navy. Born in England in 1871, Glossop served as a midshipmen in Samoan waters in the corvette HMS Calliope in 1888 and made his first visit to Australia in the flagship of the Australia Squadron, HMS Orlando. He served as a navigator lieutenant in HMS Royalist, again in Australian waters, in 1896, and in the corvette HMS Royalist during the 'Samoan troubles' of 1899. His later service included a posting as commander in the battleship HMS Hood. In June 1911 Glossop was promoted to captain and on 26 June 1913 was lent to the Royal Australian Navy and appointed to command the newly commissioned Chatham class light cruiser HMAS Sydney.

In 1914 the Sydney participated in the capture of Rabaul from the Germans before being sent as an escort to the first convoy of Australian troops being sent to Egypt. Under Glossop's command, Sydney diverted away from the convoy and defeated and beached the German raider SMS Emden off the Cocos-Keeling Islands on 9 November 1914.

In 1915 the Sydney was sent to protect British colonies in the West Indies and in 1916 transferred to the North Sea patrolling to intercept German merchant shipping and submarines. Glossop left the ship in the February 1917 and returned to take up the position of Captain-in-Charge of Naval Establishments in Sydney. While there he married Ethel McPhillamy in January 1918.

Glossop returned to England in 1920, was promoted to rear admiral on 21 November 1921, and retired the next day. He died in December 1934.
