The list of casualties in the division is defective in that no reports have been received from the First, Third, Fourth, and Ninth Regiments Virginia Cavalry, General Fitz. Lee's brigade.

Captain J. Hardeman Stuart, who was sent to capture the enemy's signal party, was deterred by the number of the guard, but the man who had his horse left without him, and he marched afoot with Longstreet's column to Groveton, in which memorable battle he shouldered a musket and fought as a private. He was killed at the storming of Groveton Heights among the foremost. No young man was so universally beloved, or will be more universally mourned; moreover a young man of fine attainments and bright promise.
