Sorry if this is a duplicate. I've been kicked off twice now. I am seeking information about my great Uncle's Army service during WWI. The National Archives said his records were destroyed in the 1973 fire. I obtained his payroll record. I would like to know the unit he served in, locations of service and if he was wounded (I recall him telling me he was "gassed"). His name was Thomas Shields McKenzie, serial number 2060846. I understand he entered service in Chicago . Thank You. Tom Smith
