By some mistake of our guide we were carried to a point in the river which was not practicable, at the then stage of the river, as a ford--which we duly discovered after nearly drowning two or three men and horses of the ambulance train, whom we found at the head of the column when we reached the river, their usual place being in the rear. The adjutant, finding them in front, asked them, "What the deuce are you doing here--your place is in the rear?" "No, sir," said a long-backed individual of the party, in a copper colored raiment, who seemed to have been making a study of the rules and regulations as applying to his own department. "Not so. In the rear, I grant you, in the advance; in the front, if you please, in a retreat" "So be it," said I. "In with you;" and in they went, nothing loth. The river was swimming and the horses swam badly, making plunges to reach the opposite bank, which, when they gained, was steep and treacherous, and it was only after repeated efforts, and their riders getting off into the river, that they made a landing. It was apparent that this could not be the point that General Lee had crossed his division. Some one turned up who led us right. About a mile farther up we found the ford that he had crossed at, and got over without difficulty or molestation; it was scarcely swimming to the smallest horse, and directly opposite lay all of the Virginia cavalry to cover our crossing, if pressed, while it was going on. We were the first regiment that crossed; found some stacks of oats; halted, formed in squadrons, fed our horses, ate what we had to eat, rested, and, as usual, made the best of it.
