The strategy employed by the Union Army to counter Lee’s tactics was Defensive posturing.

Union General George Meade understood the significance of maintaining robust defensive positions, especially on elevated terrain such as Cemetery Ridge and Little Round Top. By constructing a solidly fortified line, the Union troops sought to withstand and counter Confederate assaults. This defensive strategy enabled them to make effective use of their artillery and infantry, forming a powerful obstacle to Lee's aggressive maneuvers. The effectiveness of this tactic was vital in achieving the Union's victory at Gettysburg.
