July 2. Withdrew at 5 P. M. from the field near the Peach Orchard and went into battery here.
July 3. About 1.30 P. M. by order of Brig. General H. J. Hunt fired on the Confederate batteries but did little damage. Opened an enfilading fire soon after on Longstreet's advancing line of infantry and assisted in repulsing the assault. A charge was made within the range of the Battery immediately afterwards by the Florida Brigade and at about the same time a Confederate battery opened on the left front which at once received the concentrated fire of the batteries of the Brigade driving the cannoneers from the guns which they abandoned.
July 4. Remained in this position until afternoon.
Casualties Killed 2 Men Wounded 1 Officer and 13 Men Total 16
