The Battle of Drewry's Bluff, sometimes called Fort Drewry, was
part of the Union's Peninsula campaign. General George B. McClellan
saw that he had a chance to become closer to his target of Richmond
by using the James River as an approaching route to the Confederate
capital. He sent several ironclads up the river, however, the
Confederate artillery on Drewry's Bluff ended the Union
advance.
