How did the confederates win the battle of Richmond VA?

The Confederates did not actually win the Battle of Richmond, Virginia; rather, the city was captured by Union forces in 1865, leading to the fall of the Confederacy. Prior to that, Richmond was a significant stronghold for the Confederates, but it ultimately succumbed to Union troops during their campaign. The fall of Richmond was a pivotal moment that contributed to the end of the Civil War. The city was abandoned by Confederate President Jefferson Davis and his government as Union troops advanced.
