April 5. — This morning the snow was between two and three inches deep. We were to have a brigade guard-mounting to-day, but owing to the storm it was put off until to-morrow. About ten o’clock the sun came out, and before night the snow had almost entirely disappeared. I went over to the Sixth Corps with Dalton about one o’clock. I saw Dr. Dalton there. Went from there with Whittier to Brigadier General Devens. General Benham called Lieutenant Roosa up to-day in regard to disturbance while the general was in Washington. Also a sutler named Jerry. There was to have been a grand review of all the cavalry to-day, but it was postponed on account of the weather. Major Cassin was here to-day. A detail of 500 men was ordered this evening.
