[July 28, 1864]
All this misfortune was occasioned by the infernal cavalry. They were sent out to guard our flanks and failed to do so. Had they done their duty, Crook would never have thought of fighting. There were about twenty thousand Rebels, while we had some six or eight thousand, all told. Our calvary is a miserable farce. They are utterly useless, in fact they were in our way. Had we not depended on them, we never would have been caught. They (cavalry) cut loose from their artillery and we, with our infantry, hauled off their guns, at the same time driving, or rather keeping, back the Rebels.
