On the 22d Gregg, Wilson, and Custer returned.

The latter had gone on his expedition as far as Hanover Station, destroyed some commissary stores there, and burned two trestle bridges over Hanover Creek.

This done, he deemed it prudent to retire to Hanovertown.

The next morning he again marched to Hanover Station, and there ascertained that a strong force of the enemy, consisting of infantry, cavalry, and artillery, was posted at the South Anna bridges.

These troops had gone there from Richmond en route to reinforce Lee.
