May 24th. Commences with pleasant weather. Light winds from S. E. Transports in sight coming down the river, and cavalry and infantry landing at the levee at Bayou Sara from four to eight A. M.; at eight thirty A. M. hove up anchor, got under way and steamed down the river; at nine thirty A. M. rounded to above Port Hudson, and fired a shell from the Sawyer rifle on poop, into the rebel batteries, to let them know we had come down to see them once more; at nine forty A. M. came to anchor five miles above Port Hudson. Received from the Albatross five rebel prisoners, hard looking fellows, on board, and kindly cared for them. These unfortunates were captured on a point of land opposite the rebel Gibraltar No. 2 of the Mississippi; at ten thirty A. M. called all hands to muster and performed Divine service. Heavy firing going on at Port Hudson. Received some more rebel prisoners this morning from the Albatross; they proved to be an officer and two privates belonging to a signal corps, they having been captured the day before by some of our pickets. Heavy firing heard in rear of Port Hudson. The mortar schooners below, engaged the rebel batteries also, from two thirty until four P. M. From four to six P. M., heavy cannonading between lower fleet and rebel batteries at Port Hudson, during this watch; also our army in rear of Port Hudson, engaged with the enemy; at six P. M. inspected crew at quarters.
