On mobilisation in 1914, the RNR consisted of 30,000 officers and men. Officers of the permanent RNR on general service quickly took up seagoing appointments in the fleet, many in command, in destroyers, submarines, auxiliary cruisers and Q-ships. Others served in larger units of the battle fleet including a large number with the West Indies Squadron who became casualties at the Battle of Coronel and later at Jutland. Fishermen of the RNR section served with distinction on board trawlers fitted out as minesweepers for mine clearance operations at home and abroad throughout the war, where they suffered heavy casualties and losses. One such casualty was armed naval drifter HMT "Frons Olivae", which hit a mine off Ramsgate on 12 October 1915 in an explosion that killed at least five other seamen. One casualty, a Newfoundlander serving with the Royal Naval Reserve, was subsequently buried in the Hamilton Road Cemetery, Deal, Kent.
