When the Union army under General William T. Sherman was executing its March to the Sea, why did it turn away escaping slaves?

Sherman's Military was provided with basic knowledge on the physical and political scene of its zone of operations by escaped slaves. Sherman's movement profited by the convergence of escaped slaves, a large number of whom had lived and worked their whole lives in the fields and towns of Georgia and the Carolinas. These escaped slaves likely gave basic knowledge on the areas of waterway intersections, blocked territory, water sources, and so on. Notwithstanding offering help with route, escaped slaves most likely had some knowledge of who were rebel supporters. These supporters, all through the war, helped or took part in guerilla attacks that bothered Association lines and emptied significant assets out of the front. Data on who upheld these assaults would have helped Sherman's armed forces execute more successful counterinsurgency tasks. It would likewise have permitted the Association powers to center the force of their "hard war" strategies on the defiance's most grounded supporters, while saving steadfast Unionists. The Union's Army's walk across Georgia and into the Carolinas would almost certainly have moved much increasingly slowly and would have experienced more guerilla opposition without the help of escaped slaves.  

Other escaped slaves gave significant battle bolster benefits that improved the portability and battle intensity of Sherman's Armed forces.

As early as August 1862, Sherman had recognized the importance of removing slaves from the South to deny them a source of economic and military labor.

Explanation:

In this historic march, General Sherman attacked the Profound South, he progressed gradually from Tennessee into Georgia, went up against every step of the way by the Confederates, who were instructed by Johnston.

Atlanta tumbled to Association powers on September 2, 1864. Savannah fell on December 21, 1864 and Sherman called it a Christmas present for President Lincoln. In 1865, Sherman's powers attacked South Carolina, catching Charleston and Columbia. In Columbia, the state capital, the Association armed force consumed slaveholders' homes and obliterated a significant part of the city. From South Carolina, Sherman's power moved north with an end goal to join Allow and wreck Lee's military.
