Battle of Gaines’ Mill

With McClellan at Richmond’s gates, Lee attacks, aiming to crush Porter’s (North) corps isolated north of the Chickahominy.

Porter holds a tiered line behind a boggy ravine, and hours of piecemeal Confederate assaults are shot to pieces crossing it.

A coordinated dusk assault, Hood’s (South) Texans at the point, finally breaks through, and McClellan’s retreat from Richmond is sealed.
