bmarine
warfare has been rather appalling, even if it fell far short of
German prophesies and hopes. During the first two weeks of February
a total of ninety-seven ships with a tonnage of about 210,000 tons
were sent to the bottom of the sea. Since then the German submarines
have taken an even heavier toll. It has, however, become next to
impossible, due to the restrictions of censorship, to compute any
accurate figures for later totals, though it has become known from
time to time that the Allied as well as the neutral losses have been
very much higher during the five months of February to July, 1917
than during any other five months.
