American Civil War
By late 1864, Lee's army was struggling, as they had less soldiers and supplies than Grant's army. Helped by Philip Sheridan, Grant's army slowly started to push into Virginia. At the start of April 1865, they won several battles against Lee's army and captured Richmond. Lee decided that he had too few soldiers to keep on fighting. He surrendered to Grant on April 9, 1865 near Appomattox Court House. Later, many other Confederate armies surrendered as well. The last Confederate general to surrender was Brigadier General Stand Watie, who surrendered on June 23, 1865, in Oklahoma.
