Overview

The Richmond–Petersburg campaign was a series of battles around Petersburg, Virginia, fought from June 9, 1864, to March 25, 1865, during the American Civil War. Although it is more popularly known as the siege of Petersburg, it was not a classic military siege, in which a city is encircled with fortifications blocking all routes of ingress and egress, nor was it strictly limited to actions against Petersburg.

Significance

The Richmond–Petersburg campaign, running from June 9, 1864, to March 25, 1865, was a prolonged series of engagements around Petersburg, Virginia, rather than a classic military siege in the strict sense — the city was never fully encircled with fortifications blocking all routes in and out, and operations extended beyond Petersburg itself. Union forces under Grant, Meade, and Butler, numbering approximately 125,000, faced Confederate forces under Lee and Beauregard totaling around 60,000. The campaign produced substantial casualties on both sides — roughly 42,000 Union and 28,000 Confederate — reflecting the attritional character of the contest. As a sustained effort to pressure the Confederate capital's supply and communications hub, the campaign occupied Lee's army for the better part of a year and constrained Confederate strategic options in the final phase of the war.
