Cold Harbor Battlefield

Cold Harbor was Grant's regret — his own words, the assault he wished he'd never ordered. The crossroads tavern ten miles from Richmond gave the battle its name; the two weeks around it in June 1864 cost 17,000 casualties and produced the war's most infamous hour: June 3, when three Union corps went at Lee's entrenchments at dawn and were broken in less time than it takes to write it.

The days before decided it — Sheridan's cavalry took the crossroads May 31, then the reinforcements piled up on both sides: Smith's corps marching wrong on bad orders, Hancock's II Corps lost on a night march, attack orders postponed twice while Lee's engineers turned a shallow line into the war's best fieldwork. When the assault finally went in, the men who'd survived the Wilderness and Spotsylvania pinned their names to their coats so their bodies could be identified — and the trenches did what trenches do.

Grant said it plainly afterward: 'I have always regretted that the last assault at Cold Harbor was ever made.' The battlefield is part of Richmond NBP now — the earthworks still legible in the woods, the Garthright House that served as a field hospital, the ground where the Overland Campaign's arithmetic finally broke. The file keeps the lesson Lee's engineers wrote: that dug-in men with repeating rifles had changed the war, and that even Grant could be taught it the hard way.

Cold Harbor Battlefield is the archive's regret file — the June 1864 assault Grant wished he'd never ordered, where men pinned their names to their coats before going at the trenches, and the earthworks still standing in the Virginia woods.
