Convoy commodore also known as commodore, convoys was the title of a civilian put in charge of the good order of the merchant ships in the British convoys used during World War II. Usually the convoy commodore was a retired naval officer or a senior merchant captain drawn from the Royal Naval Reserve. He was aboard one of the merchant ships.

The convoy commodore was distinguished from the commander of the convoy's escort, always a naval officer.

Description

Convoy commodores were based at HMS Eaglet, the Royal Navy's shore establishment at Liverpool. Commodores had a peripatetic role, sailing with each convoy as assigned in a suitable ship. This ship would be the convoy flagship, but remained under the command of its master, the commodore and his team merely taking passage. The commodores were accompanied by a small team of ratings, usually a yeoman and two or three signalers; these teams would stay together and work with the same commodore throughout the campaign, allowing a pattern of co-operation to develop. The commodores responsibilities were the management of the merchant ships of the convoy, its course and speed, and its defensive manoeuvers such as zigzag patterns and evasive actions. The commodore worked together with the senior escort officer (SOE), who was in command of the warships protecting the convoy. The SOE was ultimately responsible for the safe and timely arrival of the convoy. This situation could have been a source of friction; the SOE (usually a Lt Cdr or Commander) would invariably be junior to the commodore, often a retired Flag Officer with many years experience. In practice the two worked together pragmatically; Peter Gretton, an escort commander during the Battle of the Atlantic, describes how his instructions, which were couched in the form of suggestions, were always acted upon: He recalls only one instance where he had to "pull rank" on the commodore.

Numbers

There were 181 ocean commodores listed with Eaglet in 1943; of these 102 were Royal Navy and 57 were RNR. Of the others, eight were from Dominion navies (Four Royal Canadian Navy, three Royal Indian Navy and one Royal New Zealand Navy officers) and four from Allied navies (two Norwegian and two Dutch). Of the RN officers, 11 were retired Admirals, 33 Vice- and 53 Rear-Admirals and 13 were Captains.

During the Second World War the British ran 4,025 ocean and 10,025 coastal convoys; all had a commodore appointed, though the coastal convoys were generally led by the senior merchant captain present. Of the ocean convoys 1,480 were on the North Atlantic route, and of these 186 (12.5%) were attacked, losing one or more ships. Of the 78 Arctic convoys, 21 (27%) were attacked, losing one or more ships. 24 convoy commodores lost their lives in the course of their duties, and are recorded on the Merchant Navy War Memorial in Liverpool.
