Thursday. More or less Picket firing all night--We were aroused early, and inspection showed a lot of our horses too lame and used up for good action--So first, our good mounts were formed for moving out, and were soon off--with the Brigade and took Reb. Genl. Steward by surprise on the Deardorf Farm--on right and rear of the army line--where Steward was expected to at least annoy the rear of Genl Mead--But our boys charged him--and after severe fighting dealt him an inglorious defeat and later in the day came in and lay on arms in the rear of Meads right--While our mounted men were paying attention to Genl Steward, we fellows had our horses cared for and were marched down to the right of the main line--to occupy a gap and do Sharpshooting--at long range, with our Carbines--we soon attracted attention, and later an occasional shell fell conspicuously close--but far enough to the rear of us so we suffered no serious harm. Towards noon firing became more general and in almost all directions--and we were ordered to our horses--and joined our returned heroes, and lay in readiness for any emergency--The general battle increaced in energy--and occasional fierceness--and by 2 P.M. the canonading was most terrific and continued til 5 P.M. and was interspersed with musketry--and Charge-yells and everything that goes to making up the indescribable battle of the best men on Earth, seemingly in the Fight to the Finish--At dark, our Cav Brig--2nd Brig 2" Div--was moved to the left--many wounded came in--Taken as a whole from all one can see from one point--it seems as tho our men--The Union Army--is rather overpowered and worsted--Lay on arms to rest-- Little chance to feed and eat.
