The Battle of the North Fork of the Red River took place after the Quaker Peace Policy had expired, therefore troops from the Texas District were free to engage in combat and William Wilson was awarded his second Medal of Honor.
The Grant administration's "Quaker Peace Policy" was still in effect, which placed the appointment of Indian agents in the hands of Protestant religious organizations (Quakers were the first to participate, thus the name of the policy), not political patrons.
