ments were trained they were sent to ports on the eastern coast
and embarked for France, their places in camp being taken by new groups
of drafted men. Beginning with fifty or sixty thousand each month, the
number sent abroad was rapidly increased until by the fall of 1918 the
troops were going over at the rate of more than three hundred thousand a
month. By October 15 there were over two million of our soldiers in
France and another million and more under training in this country.
DECREASE IN SUBMARINE SINKINGS.--The Germans had boasted in vain that
their submarines would prevent the transportation of American troops to
Europe. Of the hundreds of transports engaged in this work, up to
November, 1918, only two were sunk while on the eastward voyage, and
less than 300 American soldiers were drowned. Moreover, during the year
1918 there was a notable decrease in the destruction of merchant vessels
by submarines. This was due probably to a variety of causes, but
especially to the increased protection provided by the convoy system,
and to the more efficient methods of fighting the submarines.
It has been found that it is possible to see a submarine at some
distance below the surface if the observer is in a balloon or an
airplane. Therefore the submarine hunters do not need to wait for the
submarine to show itself. The sea is patrolled by balloons and airplanes
in conjunction with fast destroyers. When the aircraft has located a
submarine, the fact is signaled to a destroyer. When the destroyer
arrives over the submarine, it drops a depth bomb, which is arranged to
explode after it has sunk to any desired depth in the water.
It is believed that the submarines are being destroyed faster than
Germany can build them, and also that it is increasingly difficult for
Germany to obtain the highly trained crews necessary to manage the
complex machinery of a submarine. For it must be remembered that the
circumstances under which submarines are destroyed almost always involve
the loss of the crew.
SUBMARINES RAID THE ATLANTIC COAST.--Unable to face the convoys of
transports, several submarines paid visits to our coast in the summer of
1918, and destroyed a considerable number of unarmed vessels, mostly
small craft. Many of the victims, indeed, were very small fishing
boats, which are, by international agreement, exempt from capture or
destruction.
