On May 22, Grant launched a major assault against Vicksburg. Higgins volunteered to act as the color bearer for his regiment on that day as the acting color bearer had been previously wounded.[3] Higgins' regiment, the 99th Illinois, and four other Union regiments attacked a section of the Vicksburg defenses held by the 2nd Texas Infantry Regiment, which succeeded in repulsing the attack. According to one of its members, Charles I. Evans, after the assault was beaten back, a color bearer (Higgins) continued to advance towards the Confederate lines. Seeing this, "at least a hundred men took deliberate aim at him, and fired at point-blank range", yet Higgins was not hit.[4] When they saw that he did not falter, the Texans then ceased firing and cheered on Higgins to keep coming, who safely reached the breastworks and was congratulated by them.
Higgins was then interrogated by the Vicksburg garrison commander, General John C. Pemberton, but refused to give him any solid information about Grant's army. He was paroled and exchanged a few days later, rejoining the 99th Illinois. He stayed with the regiment until the end of the war.
At the request of his captors, Higgins received the Medal of Honor,[5] receiving it on April 1, 1898.
Higgins died on August 15, 1917, and was buried at Holy Family Cemetery in Hannibal, Missouri.
