decisive acts was to check the secession movement in Southern California
by placing a strong detachment of soldiers at Los Angeles. This force
proved enough to stop any incipient uprisings in that part of the state.
Some of the disturbing element in this district then moved over into
Nevada where cooperation was made with the pro-Confederate men there.
The Nevada rebel faction had made considerable headway by assuring
unsuspecting persons that it was acting on the authority of the
Confederate Government. On June 5, 1861, the rebel flag was unfurled at
Virginia City. Again Sumner acted. He immediately sent a Federal force
to garrison Fort Churchill, and a body of men under Major Blake and
Captain Moore seized all arms found in the possession of suspected
persons. A rebel militia company with four hundred men enrolled and one
hundred under arms was found and dispersed by the Federals. This
decisive action completely stopped any uprisings across the state line,
uprisings which might easily have spread into California.

In the meantime, under General Sumner's direction, soldiers had been
enlisted and were being rapidly drilled for any emergency. The War
Department, on being advised of this available force, at once sent the
following dispatch, which, with those that follow are typical of the
correspondence which the Pony Express couriers were now rushing across
the Continent toward and from Washington.

Telegraph and Pony Express.

Washington, July 24, 1861.
