Friday. Canonading commenced early--and battle was on again in full intensity at 10 ock we were ordered to the Front and Center, but immediately removed to the right of the Center--had some skirmishing. Pretty lively--Our squadron almost ran into a Rebel Battery with a Brigade of Cavalry maneuvering in the woods. They didn't want to see us, but moved left-ward and we held the woods all P-M.--All seemed rather quiet for several hours--From 1 1/2 til 4 P.M- there was the heaviest canonading I ever have heard--One constant roar with rising and falling inflections--Our Boys opened 54 guns at the same time on the Rebel lines and works from a little conical hill, Cemetary Ridge. We were picketing in the rear and on the right of it--Many shells came our way--some really quite near--But it is wonderful how few really made our acquaintance.
