Her most memorable exploit was the capture on 17 April 1861 off Indianola, Tex., of SS Star of the West, the first Union transport to make news in the Civil War.
During the early part of 1862 General Rusk was placed by General Hebert, commanding Texas Marine Department, under the control of Maj. T. S. Moise, Assistant Quartermaster, who colluded to transfer the steamer to his associates, authorizing them to place her under the British flag and employ her in blockade running. After a single successful round-trip there under the name Blanche she was bound for Havana in October 1862 when pursued by USS Montgomery, Comdr. C. Hunter, USN. While attempting to escape the steamer was run aground near Marianao, Cuba, and seized by a Montgomery boat crew. Efforts to get her towed off the bar and underway again ended when fire broke out and consumed both ship and cargo. The incident occasioned strong protest from England under whose flag she sailed, and Spain in whose territorial waters she was captured.
