 For the morning assault on June 3, he can account for only 3,500 to 4,000 Union killed, wounded, and missing, and estimates that for the entire day the Union suffered about 6,000 casualties, compared to Lee's 1,000 to 1,500.Rhea noted that although this was a horrific loss, Grant's main attack on June 3 was dwarfed by Lee's daily losses at Antietam, Chancellorsville, and Pickett's Charge, and is comparable to Malvern Hill.The battle caused a rise in anti-war sentiment in the Northern states.
