In what way was petersburg a crucial victory for the union in the civil war

The siege of Petersburg was 10 moths long and arduous as both sides had it rough. The forces of the Confederate were dug deep in the long trenches making this an extremely difficult battle but it also made the Union victory that much important as it made general Lee go into hiding and after winning this battle the Union managed to secure an important Confederate town Richmond. This all paved way for the end of the Civil War.

The Siege of Petersburg took place from June of 1864 until March of 1865. This loss was tremendous for the Confederate army, and it set the stage for the subsequent defeat at Five Forks the following month, for the surrender of Petersburg in April, and for the surrender of Richmond. These events eventually led to the Appommattox, at which point General Lee surrendered. Thus, Petersburg set into play a cascade of events that were very meaningful for the Union Army.
