This Week in the Civil War - 535
On Saturday, March 28, 1863 near Patterson, Louisiana, Confederate land and Union naval forces clashed. The USS Diana had been instructed to make a reconnaissance to the Atchafalaya River; accompanying her were two Union infantry companies.
Confederate artillery assaulted the Diana, killing her master and senior mate and disabling her steerage. The Diana went aground where she was totally at the mercy of the Confederates’ fire. After more than two and one-half hours of withstanding the Confederate assault, the remaining ship’s officers surrendered their ship.
The Diana’s crew suffered 33 killed or wounded, including 7 officers, and dozens of captured infantry. The USS Calhoun, sent to assist the Diana, also ran aground but refloated herself before she could be attacked.
