and was stationed on the White River. Marmora patrolled on the Mississippi River in the later part of the year, seizing cotton owned by known Confederate sympathizers. For a time in November, she was stationed at the mouth of the Yazoo River to prevent the Confederates from blockading it. As of December 1, she was stationed at Island No. 70 and was commanded by Acting Master Thomas Gibson. By January 14, 1864, she had shifted to being stationed out of Greenville, Mississippi. Yazoo City and later service On February 2, Marmora began a movement up the Yazoo River along with Prairie Bird, and the tinclads Romeo, USS Exchange and USS Petrel. The naval force was led by Lieutenant Commander Elias K. Owen, and was working in conjunction with a Union Army brigade commanded by Colonel James E. Coates. Later that day, the Union forces skirmished with Confederate land forces near Satartia, Mississippi, and on February 3 and 4 fought against land-based Confederates in the Liverpool, Mississippi area. On February 4, Marmora and Exchange pushed on to Yazoo City, but came under artillery fire and withdrew to Satartia.

Late on February 14, the expedition occupied Greenwood, upriver from Yazoo City. The Union forces collected about 450 cotton bales in the area, while Marmora scouted up the Tallahatchie River. They began returning downriver on February 19, returning to Yazoo City on February 28. By late February, the Union vessels remaining on the Yazoo were Petrel and Exchange at Yazoo City, Prairie Bird at Liverpool, and Marmora running patrols on the river. After the Meridian campaign ended, Confederate cavalry was free to return to the Yazoo River area, and attacked Yazoo City on March 5. Marmora was present at the city and fired on the Confederate attackers. A 12-pounder howitzer from Marmora was sent ashore, with a crew under the command of Gibson. The howitzer fired rapidly, and participated in repulsing the Confederate attacks on Yazoo City. Three seamen from Marmora received the Medal of Honor for their actions at Yazoo City: William J.
