Until shadows fall

the long version

Peace has been established between the United States Army and the Comanche nation, citizens who lost children to Comanche raids over the years are pressuring Congress for their return. The War Department has delegated the task to Colonel Frazer at Fort Elliott in Texas, but the mission is preposterous at best. The male captives regard themselves as Comanches now and the women are scorned by the whites for co-habiting with their captors. The army is expected to match these young adults with families that lost them as toddlers - and the Comanches would rather resume the war than submit to this degradation.
