# Left Flank Movement Across the Chickahominy and James—General Lee—Visit to Butler—The Movement on Petersburg—The Investment of Petersburg explained — Personal Memoirs of Ulysses S. Grant > Chapter companion for Personal Memoirs of Ulysses S. Grant by Ulysses S. Grant. ## What happens Grant executes a risky left flank maneuver, crossing the Chickahominy and James Rivers to move the Army of the Potomac south of Richmond. He sends Sheridan with two cavalry divisions to link with Hunter and disrupt Confederate supply lines. The army crosses the James on June 14-15, and Grant orders an immediate assault on Petersburg. Despite initial opportunities, delays allow Beauregard to reinforce and fortify, leading to heavy fighting from June 15-18. The chapter concludes with the beginning of the siege of Petersburg, as Union forces invest the city and cut its railroads. ## Themes in this chapter ### Leadership and Humility Grant acknowledges his own miscalculation regarding the delay in capturing Petersburg, showing humility in assessing his orders. ### The Horrors and Cost of War The chapter describes heavy losses, severe fighting from June 15-18, and the immense logistical strain of the campaign. ### National Union and Constitutional Crisis The movement to besiege Petersburg is part of the broader effort to preserve the Union and defeat the Confederacy. ## Character check-ins ### Ulysses S.

Grant decided to shift the army south of the James River in a flanking maneuver. _This decision initiated the move toward Petersburg._ > If General Hancock’s orders of the 15th had been communicated to him, that officer, with his usual promptness, would undoubtedly have been upon the ground around Petersburg as early as four o’clock in the afternoon of the 15th. Grant believed that if Hancock had received his orders promptly, he could have reached Petersburg by 4 p.m. on June 15. _Grant reflects on a missed opportunity to capture Petersburg quickly._ > I do not think there is any doubt that Petersburg itself could have been carried without much loss; or, at least, if protected by inner detached works, that a line could have been established very much in rear of the one then occupied by the enemy. Grant thought Petersburg could have been taken with minimal casualties, or at least a more advantageous line could have been secured. _Grant assesses the cost of the delay in the assault._ > Thus began the siege of Petersburg. This marked the start of the prolonged siege of Petersburg. _The chapter concludes with the beginning of the siege._ ## Links - HTML: https://www.betterreads.online/discover/personal_memoirs_of_ulysses_s_grant_se/chapters/lvi - Book: https://www.betterreads.online/discover/personal_memoirs_of_ulysses_s_grant_se - All chapters: https://www.betterreads.online/discover/personal_memoirs_of_ulysses_s_grant_se/chapters
