Union infantrymen finally take Marye's Heights in the Second Battle of Fredericksburg
With Hooker facing defeat at Chancellorsville, he ordered Major-General John Sedgwick to advance from Fredericksburg and reinforce him. To do so Sedgwick had to take Marye's Heights outside the town which he did around noon on the third bloody assault. About 1,500 men from both sides became casualties. Sedgwick's VI Corps then moved on but was turned away in the evening by Confederate forces under General Jubal Early. (By John Osborne)
