Question. What was the strength of your whole command in front of Jackson, independent of General Porter's corps, on the 29th of August?
Answer. I cannot tell with exactness, since, in the active operations, where we were fighting almost every day, I had received no reports of casualties, either in killed, wounded, or stragglers. I can give, I suppose, something like an approximation to it. I think that until half-past 5 in the afternoon of the 29th, when McDowell's command arrived on the field, our whole force amounted to about 24,000 or 25,000 men, independently of McDowell's and Porter's corps; that may be an overestimate, probably is an overestimate, from the fact which I have stated, that I did not have any reports of casualties, either in killed, wounded, or stragglers, and the stragglers formed an exceedingly large part of those absent from every action.
Question. You have given an estimate of the force of Jackson; did you include in that estimate the force of Longstreet?
Answer. I did not.
Question. What was the strength of McDowell's corps ont he 29th of August?
Answer. As with the others, I had received no reports from McDowell's corps; I estimated, however, the fighting force that McDowell brought on the field at about 12,000 men. It may have exceeded that, or it may have been less; that is a mere estimate in the absence of any reports of casualties or stragglers from that corps for two weeks previous, during which time we had been almost constantly marching and fighting the enemy, and during which period there was no time to make out returns.
Question. Can you give an estimate of the force of Longstreet at that time?
Answer. There were various accounts of Longstreet's forces. According to my own belief, derived from these various sources of information, I think Longstreet had, perhaps, 17,000 men-from that up to 20,000-though, of course, such estimate is not very reliable.
