"When war came the ships were commissioned, without crews. This could be done because from the latter part of the seventeenth century there was a permanent force of officers. Then the officers had to find their own crews. They began by drawing their proportion of marines, and then proceeded to invite seamen to volunteer. In this way they got a number of skilled seamen, men who had been in the navy before, and came back to it either as petty officers or in the hope of becoming so. Then warrants to impress seamen would be issued. Theoretically the impress was merely a form of conscription, the Crown claiming by prerogative the right to the services of its seafaring subjects. Practically a good deal of violence was at times necessary, as many of the men, preferring to sail in merchant ships, or wishing to wait for a proclamation of bounty, tried to avoid arrest. The scuffles that took place on these occasions gave the impress service a bad name, not altogether deserved, for real efforts were made to avoid hardship, and in any case the number of men raised in this way was greatly exaggerated by popular report." There was no compulsion during the Great War to join any unit of the British fleet. Therefore all were either in the regular service, reservists or volunteers. The need was made known not only throughout the British Isles, but also from Vancouver to Cape Town, Sydney and Wellington, and men in all walks of life, but with either the _Wander-Lust_ or true love of the wide open sea in their blood, rallied from all parts of the far-flung Empire to the call of the White Ensign. In order to obtain some 6000 officers and nearly 200,000 trained or semi-trained men, new sources of supply had to be tapped. Already the great battle fleets, brought up to full war strength and with adequate reserves, had absorbed nearly all the Reserve officers who could be spared from the food and troop transports.[2] First came the great sea-training establishment of the Empire--the Mercantile Marine and its retired officers and men--already heavily depleted. Then the yacht clubs from the Fraser to the Thames and Clyde. Thousands of professionals and amateurs came overseas to the training cruisers and the "naval university," Canada alone supplying several hundred officers. Doctors came from the hospitals and from lucrative private practices. The engineering professions and trades supplied the technical staffs and skilled mechanics. The great banks and city offices yielded the accountants, and the fishing and pleasure-boating communities, not only of Great Britain, but also of the Dominions and Colonies, yielded the men in tens of thousands. In this way the personnel of the new navy was completed in a very few months.
