The ranks were thin and irregular, and we found a stream of people strung from the hospital across Bull Run, and far toward Centreville. After putting in motion the irregular square in person, I pushed forward to find Captain Ayres's battery at the crossing of Bull Run. I sought it at its last position, before the brigade had crossed over, but it was not there; then passing through the woods, where, in the morning, we had first formed line, we approached the blacksmith's shop, but there found a detachment of the secession cavalry and thence made a circuit, avoiding Cub Run Bridge, into Centreville, where I found General McDowell, and from him understood that it was his purpose to rally the forces, and make a stand at Centreville.
