cavalry has done great damage in their rear. Our fourth detachment
received a rebel gun to-day, in place of the one lost on the tenth of May.
Two more guns and caissons were taken from the enemy to-day. A mortar
battery was playing on the enemy's lines all day. Rainy weather.

_Sunday, May 15._--Our battery left at half-past one o'clock in the
morning, marching but a few miles. The Second corps was relieved by the
Eighth, General Augur, being in reserve for a few days. We rested all day.
A heavy shower fell in the evening.

_Monday, May 16._--Remained quiet all day. It was read in line that
twenty-three thousand men, reinforcements, were on the way.
