History

The Mercantile Marine War Medal was established in 1919 and awarded by the Board of Trade to the officers and men of the British Mercantile Marine, later the Merchant Navy, for service at sea in the First World War. It honoured a particular kind of courage: peacetime mariners who kept sailing through waters where enemy submarines hunted, at a cost of nearly 2,500 merchant vessels and more than 14,000 lives to enemy action.

A mariner qualified by making one or more voyages through a danger zone, or by serving at sea for at least six months between 4 August 1914 and 11 November 1918. About 133,135 were awarded, over 17,000 to seamen born outside the United Kingdom. Merchant service could be combined with the British War Medal and, where the mariner also served in the fighting forces, with the Victory Medal and a star, though service solely in the Mercantile Marine did not qualify for those. As an Imperial award it retains its place in the Australian Order of Wearing.

Design & ribbon

The medal

The medal is a bronze disk, 36 millimetres in diameter, with a straight non-swivelling suspender. The obverse bears Bertram Mackennal's effigy of King George V. The reverse, designed by Harold Stabler, shows a merchant steamship ploughing through heavy seas with a submarine sinking to port and a sailing ship beyond, inscribed FOR WAR SERVICE, MERCANTILE MARINE, 1914-1918 within a laurel wreath.

The ribbon

Mercantile Marine Medal

Green and red divided by white, a ship's running lights.

The ribbon has a green band and a red band separated by a thin white stripe, representing a ship's port and starboard running lights with the white masthead steaming light between them.

Eligibility

The medal was awarded to mariners of the British Mercantile Marine for war-zone service at sea.

  • One or more voyages through a danger zone qualified a mariner, as did at least six months of service at sea between 4 August 1914 and 11 November 1918;
  • It could be held alongside the British War Medal, and, for those who also served in the fighting forces, the Victory Medal and a star; service solely in the Mercantile Marine did not qualify for the Victory Medal or the stars;
  • No clasps were awarded. As an Imperial award it retains its place in the Australian Order of Wearing.
The civilian service that fed a nation: The merchant seaman was a civilian who ran a warrior's risk: unarmed ships, hidden submarines and the cold Atlantic. This medal, uniquely awarded by the Board of Trade rather than the services, honours that service, and its running-light ribbon is one of the most evocative in the whole system. Details should be confirmed against the recipient's documentation.

Order of wear

Imperial awards were the honours of Australia before the Australian honours system was established in 1975, and they retain their place in the Order of Wearing. They are worn after the Australian honours of their kind and among the Imperial awards in the order set by the Australian Order of Wearing, which follows the British order of precedence.
