A Doughboy In The Trenches
The term doughboy was used for members of the American Expeditionary Force that fought in France during WWI. The name itself though was used long before that. During the Napoleonic wars, a doughboy referred to a fried flour dumpling that was popular among the British in Spain. Eventually, this small cake would evolve into the modern doughnut.
The term doughboy in reference to soldiers, however, started a little after that. During the Mexican – American War (1846-48) the term was used for American infantry and while no one knows for sure where the term came from there are a number of possibilities.
One theory has to do with the environment that the infantry marched through in Mexico. It was dry and very dusty. As they marched mile after mile they became covered head to toe in a fine layer of dust. To some, it looked like they were covered with flour. The cavalry, with no love lost for the infantry, took to calling them doughboys as a derogatory term. Sounds about right and would fit in with other appellations for American soldiers such as dog face, grunt, joe, etc.
In the years between the Mexican War and WWI, the name was not used very much though, only becoming popular again when the Americans showed up in France. This time though it may have come from another source. It seems that along with hundreds of thousands of infantry, the Americans also sent the Salvation Army volunteers to support the troops. One of their best-known services for the men was the making of doughnuts. Millions of them that were delivered to the American troops serving on the front-lines. It would not be a huge jump in logic to see French and British troops chiding the Yankees and amount of fried dough they were subject to. Doughboy would not be that much of a leap. (It could also have been used to mock the perceived weakness of the raw and unblooded American troops.)
Whichever theory you want to subscribe to the fact is the term doughboy is one that will always bring to mind the American soldiers in the muddy and dark trenches in France, much like those young men in the picture above.
