R. C. Drum, June 24, 1862

COMMANDING OFFICER DISTRICT OF OREGON, Fort Vancouver, Wash. Ter.:

SIR: The mode proposed in your letter of the 19th instant for supplying Fort Colville is approved by the department commander. The general directs that the Oregon cavalry must be on the emigrant route in time to protect the approaching emigration. The obstructions caused by the recent freshets will no doubt be removed in time to permit an early march. The troops under orders to relieve the present garrison of Fort Colville will, the general directs, be paid previous to leaving Fort Vancouver, if it is possible to do so.

Very respectfully, your obedient servant,
