Answer:
Avoid a protracted guerilla war waged by disgruntled Confederate soldiers, is the right answer.
Step-by-step explanation:
A meeting to discuss the terms of the army's surrender was organised by Confederate General Joseph E. Johnston with Union General Sherman. In the meeting, both the generals were opened to negotiations because like the army of Lee, the army of Johnston was neither surrounded nor in the poor condition. As a result, Johnston wanted terms those were different than given to Lee by Grant.
Aware of the guidance given to General Grant by the then U.S President Abraham Lincoln General Sherman decided to offer generous terms of surrender to the men of Johnston. Like other officials, Sherman was afraid of the fact the Johnston's army might leave quietly and take to the hills and wage a protracted, guerrilla war.
