The Signal Corps was promptly organized, and performed service of the
most difficult and important character. Its operations during the war
covered the electrical connection of all coast fortifications, the
establishment of telephonic and telegraphic facilities for the camps at
Manila, Santiago, and in Puerto Rico. There were constructed 300 miles
of line at ten great camps, thus facilitating military movements from
those points in a manner heretofore unknown in military administration.
Field telegraph lines were established and maintained under the enemy's
fire at Manila, and later the Manila-Hongkong cable was reopened.

In Puerto Rico cable communications were opened over a discontinued
route, and on land the headquarters of the commanding officer was kept
in telegraphic or telephonic communication with the division commanders
on four different lines of operations.

There was placed in Cuban waters a completely outfitted cable ship,
with war cables and cable gear, suitable both for the destruction of
communications belonging to the enemy and the establishment of our own.
Two ocean cables were destroyed under the enemy's batteries at Santiago.
The day previous to the landing of General Shafter's corps, at
Caimanera, within 20 miles of the landing place, cable communications
were established and a cable station opened giving direct communication
with the Government at Washington. This service was invaluable to the
Executive in directing the operations of the Army and Navy. With a total
force of over 1,300, the loss was by disease in camp and field, officers
and men included, only 5.
