South Dakota’s wars, generation by generation

South Dakota’s military history reaches from the Plains Indian Wars — including the tragedy at Wounded Knee in 1890 — through the Spanish-American War and the World Wars, its Guard units raised from farm and ranch country.

The home front

The wars of the twentieth century were fought at home as well — in training camps, National Guard armories, war plants, and Liberty-bond drives. Draft registrations, service cards, and unit histories place a South Dakota family in each conflict, generation by generation.
