Meantime a large fleet of steamboats was assembling from St. Louis and Cairo, and Admiral Porter dropped down to Memphis with his whole gunboat fleet, ready to cooperate in the movement.  The preparations were necessarily hasty in the extreme, but this was the essence of the whole plan, viz., to reach Vicksburg as it were by surprise, while General Grant held in check Pemberton’s army about Grenada, leaving me to contend only with the smaller garrison of Vicksburg and its well-known strong batteries and defenses.  On the 19th the Memphis troops were embarked, and steamed down to Helena, where on the 21st General Steele’s division was also embarked; and on the 22d we were all rendezvoused at Friar’s Point, in the following order, viz.:
