Grant decided to lay a formal siege, aiming to outlast the enemy and avoid further casualties. _Grant shifts strategy after the costly assault of May 22._ > The crossing of troops at Bruinsburg commenced April 30th. On the 18th of May the army was in rear of Vicksburg. The army crossed at Bruinsburg on April 30 and was behind Vicksburg by May 18. _Timeline of the rapid campaign from crossing to investment._ > We had no siege guns except six thirty-two pounders, and there were none at the West to draw from. Admiral Porter, however, supplied us with a battery of navy-guns of large calibre. The army lacked siege artillery, but Admiral Porter provided heavy naval guns for the siege. _Naval support was crucial for the siege operations._ > I at once wrote to McClernand, directing him to send me a copy of this order. He did so, and I at once relieved him from the command of the 13th army corps and ordered him back to Springfield, Illinois. Grant demanded a copy of McClernand's unauthorized order and then relieved him of command, sending him to Illinois. _Grant's decisive action against McClernand for violating orders._ ## Links - HTML: https://www.betterreads.online/discover/personal_memoirs_of_ulysses_s_grant_se/chapters/xxxvii - 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
