In July 1862 she was spotted on the Black River in company with a Confederate gunboat, probably carrying troops and supplies.
[1] Under the daring and gallant Col. Charles R. Ellet, Queen of the West got underway, after delays, and early in the morning of 2 February 1863, came in sight of Vicksburg.
[1] The Confederates opened a heavy fire on Queen of the West, which was partially turned to make a better angle to deflect projectiles.
But, with guns shotted with incendiary projectiles, Ellet directed a fire on Vicksburg and rammed her.
[1] "The Vicksburg," reported Ellet, "was the largest and strongest steamer on this river, and I think they were preparing to use her against our transports, being very fleet."
But, in December 1863, a report to Secretary of War E. M. Stanton gave intelligence of a "very formidable vessel" being finished near Mobile.
