Apparently, Grant had heard rumors of the fall of Mobile. In any case, he wants to protect Corinth, MS, by taking Holly Springs. As I’ve mentioned before, Holly Springs was a railroad junction to the east of Corinth, and a key spot for logistical support. Grant knew there was a Confederate buildup there, and aimed to preclude any advance by assaulting them first.
JACKSON, November 1, 1862.
General HAMILTON, Corinth, Miss.:I have before me a Jackson (Mississippi) paper, which makes no mention of the fall nor even of attack upon Mobile. It may be so, however. We will make the move indicated in my former dispatch, and, if practicable, drive the enemy from Holly Springs. Corinth will then be covered.
U. S. GRANT,
Major-General.
