How did General Philip H. Sheridan use winter campaigns against Plains tribes?

General Philip H. Sheridan utilized winter campaigns as a strategic tool to force Plains tribes into submission by exploiting their seasonal vulnerabilities.

Recognizing that the cold weather and the scarcity of grass forced scattered bands to congregate for the winter, Sheridan orchestrated military operations designed to strike these concentrated groups when they were least mobile and most reliant on their stored resources. His strategy relied on the convergence of multiple army columns to track and attack these encampments, effectively shattering the tribes' economies and morale through constant flight and the destruction of their winter supplies.1

This approach was notably implemented during the 1868–69 campaign, where Sheridan’s forces, including George A. Custer, destroyed the Washita River encampment and dealt blows to other groups, eventually compelling many to accept reservation life. By maintaining relentless pressure through the winter months, the military aimed to make the cost of resistance unsustainable, as the physical and economic toll of these campaigns proved more devastating to Native American resistance than individual skirmishes.1
