During the first twelve months of it, February, 1917, to February, 1918, a total of sixty-nine American ships, representing about 170,000 tons, were sunk by submarines, mines, and raiders. Over 300 lives were lost with these boats. Figures in regard to the French and Italian losses are incomplete. From available sources, however, it appears that during the six months' period, August, 1917, to February, 1918, the French merchant marine lost by U-boat attacks seventy-three steamers of over 1,600 tons, fifty-two steamers of under 1,600 tons and thirty fishing boats. In the same period U-boats sank sixty-one Italian steamers and forty-six Italian sailing vessels.
