"My brother returned this evening. He did not succeed in joining the Monticello Guard from Carroll Parish. They had gone up the river, but he joined the Jeff Davis Guards at Vicksburg, and was elected 3rd lieutenant. It is an Irish company officered by Americans. It was raised by Dr. Buckner and Capt. Manlove, and if my brother had seen either of them on his way to New Orleans, they would have given him captaincy. Tom Manlove is captain. Uncle Bo cannot join it as private, as association would not be pleasant; and he is so disappointed not to be with my brother. He hopes to get in the Volunteer Southrons, which will leave Vicksburg in a few days. The Jeff Davis Guards leave for Richmond (Va.) on Monday, and so my brother and Uncle Bo get off in the morning as early as possible."
