Which event marked the end of a significant military campaign led by Sherman?

The capture of Savannah marked the end of a significant military campaign led by General William Tecumseh Sherman known as his "March to the Sea." This campaign began after the burning of Atlanta, where Sherman sought to bring the war directly to the civilian population in an effort to undermine the Confederacy's ability to sustain its war effort. The march from Atlanta to Savannah in late 1864 was characterized by widespread destruction of infrastructure and resources, aimed at weakening Confederate morale and capacity.

Taking Savannah was strategically important as it provided Sherman with a significant port city, bolstering Union logistics and control in the South. This capture effectively concluded the military operations of Sherman's campaign in that region, showcasing the success of his strategy of total war. In contrast, events like the siege of Petersburg and the signing of the Truce at Appomattox occurred later in the war and involved different military strategies or circumstances not directly tied to the specific campaign Sherman was engaged in at that time.
