One regiment of infantry and five companies of cavalry have been accepted from California to aid in protecting the overland mail route via Salt Lake.

Please detail officers to muster these troops into service.  Blanks will be sent by steamer.

By order:  George D. Ruggles. 
Assistant Adjutant General.

While recognizing the great need of extending proper military protection to the mail route, it must have been disheartening to Sumner and the loyalists to see this force ordered into service outside the state.  For now, late in the summer of 1861, the time of national crisis — the Californian trouble was approaching its climax.  On July 20, the Union army had been beaten at Bull Run and driven back, a rabble of fugitives, into the panic stricken capital.  Then came weeks and months of delay and uncertainty while the overcautious McClellan sought to build up a new military machine.  The entire North was overspread with gloom; the Confederates were jubilant and full of self-confidence.  In California the psychological situation was similar but even more acute, for encouraged by Confederate success, the rebel faction became bolder than ever, and openly planned to win the state election to be held on September 4.  If successful at the polls, the reins of organized political power would pass into its hands and a secession convention would be a direct possibility.  And to intensify the danger was the confirmed indifference or stubbornness of many citizens who seemed to place petty personal differences before the interests of the state and nation at large.

As is well known, Lincoln and the Federal Government accepted the defeat at Bull Run calmly, and set about with grim determination to whip the South at any cost.  The President asked Congress for four hundred thousand men and was voted five hundred thousand.  In pursuance of such policies, these urgent dispatches were hurried across the country:
