ガバヌーア・ウォーレン
第3軍団のダニエル・シックルズ少将は命令を無視し、部隊を動かし、重要な地形に無防備なままに置いた。同軍のガバヌーア・ウォーレン准将は丘の戦術的な重要性を認識し、緊急にアメリカ連合国陸軍に対し、その丘の占領を求めた。ヴィンセントの旅団も元に、ウォーレン軍の士官がやって来て、ヴィンセントは絶好の位置にあると気付き、"I will take the responsibility to take my brigade there." Pvt. Oliver Willcox Norton, Vincent's brigade standard bearer and bugler, later wrote that he and Vincent made a reconnaissance of the Confederate forces as the brigade was moving into position, "While our line was forming on the hill at Gettysburg I came out with him in full view of the rebel lines. They opened two batteries on us instantly, firing at the colors. Colonel Vincent looked to see what was drawing the fire and yelled at me, "Down with the flag, Norton! Damn it, go behind the rocks with it."と言って、Little Round Top防衛を決定した。
