 Since domiciliary care was available at all state veterans homes, incidental medical and hospital treatment was provided for all injuries and diseases, whether or not of service origin.Indigent and disabled veterans of the Civil War, Indian Wars, Spanish–American War, and Mexican Border period as well as discharged regular members of the Armed Forces were cared for at these homes.Congress established a new system of veterans benefits when the United States entered World War I in 1917.
