The two battles that proved to be pivotal in undermining General Robert E. Lee's efforts to protect Richmond were the Battle of Gettysburg in July 1863 and the Siege of Petersburg, which began in June 1864. The defeat at Gettysburg marked a significant turning point in the war, as it halted Lee's invasion of the North and diminished Confederate morale.
