Teachers Whiskey During World War One, Was Whiskey/bourbon A Common Beverage Among The Soldiers?

During world war one, was whiskey/bourbon a common beverage among the soldiers? - teachers whiskey

HELP PLEASE! This is a bet with my teacher of social studies. On a piece of the Word Vocabulary bourbon. I wrote "an alcoholic beverage. She said he was referring to the French royal family of Bourbon. But he said if he could find a source who said he drank bourbon in the trenches, or among the soldiers, they gave me the credit and say he was wrong before the whole school. So please, if you know how to answer the position order, with a reliable source. THANK YOU!
