I wish this was about WW2, so many more records easily available. Green huh? Going punk or whatever they're called now? LOL
OK, I am in the midst of the research and it is a bit of fun. I have 4 windows open with 18 tabs across them trying to cross reference data. The problem lies in the Army was just not that organized and during organization, a lot of units used the same numerical designation, but were a totally different unit and many times, under different commands.
The Quartermaster Corps and the Corps of Engineers are two separate organizations in the Army hierarchy, then as well as now. However, some of the units under them had a shared purpose with slight differences. The Quartermaster Corps unit were also involved in forestry projects, but their duty was to basically supply the home front for materials needed to create various military supplies. The Spruce Production Division is an example. Whereas the Engineers were involved in supplying the finished wood needed by the Army itself to fight the war. Most of these Forestry Units of the Engineers went to France and operated sawmills as well as harvesting of wood there. Everything was wood back then, wood for barracks, trench supports, railroad ties, etc. So it is easy to get them crossed and a devil of a time to figure out who was what and was under whom? LOL
I believe I need to make a Corps of Engineers category under Category: United States Army, World War I and then add the 20th Engineer Regiment to that category as well as a sub category for Category: American Expeditionary Force (AEF), World War I. I just need a little time to go through the records as I have to read chapters in books to make sure I am correct in my assumptions so far. Sadly, no quick tables already made up for these units.
So give me a little while and I'll let you know when I've finished. Probably tomorrow or Wed.
Now to Friday and his unit. I did find mention of a 304th Service BN.unit as a blurb in one book with no a definition of who or what. I did find a 304th Labor Battalion under the Service of Supply (AEF) and the 304th Quartermaster Labor Battalion on the American Battle Monuments Commission website and those listed all appear to be from North and South Carolina. As a note, most of these Service and Labor Battalions appear to be WW1 code for 'colored' troops. Need more research on that. Need to see how the S.O.S. (AEF) and Quartermasters Corps interacted.
So hope this helps a little and I will get back once I have it figured out how to set up the 20th Engineers and the subordinate units.
One last question, are going to change your Profile photo to one with green hair?
