The search for the wounded was very thorough, and I am confident this number could not have been much increased after I left Frederick.
To Lieutenant-Colonel Blakely, commanding cavalry forces, who occupied Federick and the battle-field immediately after the rebel evacuation, we were indebted for the prompt detail of a burial party.
The Confederates left 405 of their wounded in the hospital at Frederick. In addition to these a number of cases, not fewer, I think, than 30, were left in various country houses, making the total number now in our hands at Frederick 435. Most of these were serious cases and could not be carried away.
Of the number of Confederates killed I have no accurate information. I heard it variously estimated at from 150 to 275. From various circumstances, I judge the latter number to be not far from the correct one. The lost, certainly, two colonels, whose names I do not remember, but who seemed to be highly esteemed. they sustained other losses in officers, but I am unable to give you any reliable information concerning them.
I am, very respectfully, your obedient servant,
G. K. JOHNSON,
Medical Inspector, U. S. Army.
