were assigned to the expedition. Marmora, with seven other warships and three coal barges, entered Moon Lake on February 20 or 21, where they waited for a number of transports carrying Union Army troops. The expedition continued through Yazoo Pass itself on February 26, reaching Coldwater, Mississippi two days later. The narrow channel forced the vessels to advance in a single-file line, so Marmora and the other tinclads assigned to the expedition were distributed throughout the column, to best protect the troops transports and expedite the movement of coal barges. On March 8, Marmora, a towboat, and a transport containing the 29th Iowa Infantry Regiment were left behind at a point on the Tallahatchie River to guard two coal barges. By March 13, Marmora had gone back towards the Mississippi River for supplies. That day, she met a squadron of vessels loaded with troops for the expedition; Marmora escorted the squadron through Moon Lake to Yazoo Pass the next day. March 14 saw Marmora engaged in a minor skirmish against Confederate land forces. Two days later, Marmora led the vessels through Yazoo Pass. On March 21, Marmora rejoined the main expeditionary force on the Tallahatchie, together with the ships she was escorting. The combined group then moved back down the Tallahatchie towards Confederate-held Fort Pemberton. On March 26, Marmora was released from the expedition to escort a group of transports back upriver; she also carried dispatches. Marmora arrived at Helena on March 27, slowed by her boiler problems, before leaving to return to the Yazoo Pass expedition the same day, along with a coal barge. April 16 saw another minor skirmish between Marmora and Confederate forces, but on April 17 Marmora again left the expedition bearing dispatches and in need of repairs. She spent the next several months on patrol and supply duties, and was reported to be based at the mouth of the Yazoo as of May 8. Late on June 13, Marmora was fired on by Confederate guerillas near the town of Eunice, Arkansas. The next day, the steamer Nebraska, a transport with the United States Quartermaster Department, was fired on in the same area, prompting retribution from Marmora. Marmora fired on the riverbank for two miles up and down from Eunice, and then landed armed parties that burned every structure within a mile of Eunice, including a warehouse and railroad depot. Eunice was completely destroyed during the
