German-Americans During World War I
One interesting incident of German-American opposition to America's involvement in World War I happened in Joplin in the early summer of 1918. A German man named Frank L. Misch was drinking in the St. Joe Saloon on the night of July 2 when he overheard a young man named Albert Thomas telling the barkeeper that he was getting ready to enlist in the army. Misch broke into the conversation to advise Thomas against enlisting, telling him that he was crazy to go to war and put himself up as a target for the Germans. Misch said that the Germans were too smart for us (i.e. Americans) and that if we did not leave them alone they might come over here and kill us all. He added that all his family except his immediate family were in Germany, that he sympathized with the Germans, and that America had no business getting involved in the war to begin with.
About midnight, Misch became so boisterous that the saloonkeeper sent for a police officer, who arrived and placed Misch under arrest. He was taken to the lockup and held overnight. The next day, an agent of the Bureau of Investigation (forerunner of the FBI) came to Joplin to investigate the case. The detective interviewed the young man, the barkeeper, and a taxi driver who was in the bar at the time of the incident, and all three told him essentially the same thing: that Misch said he had two sons in the U.S. Army but that he expressed himself repeatedly in favor of Germany, that he advised Thomas not to join the military, and that, although he had been drinking, he did not appear to be drunk.
The G-man also went to the jail and interviewed Misch himself. Misch said he had drunk about a dozen glasses of beer and one or two shots of whiskey. He claimed that he had been drunk and that his memory of the incident in the bar was hazy. He said he recalled having a conversation with the young man but didn't remember exactly what was said, only that it was something about the war. He admitted that he might have made the statements the witnesses against him said he made but he did not know. A judge heard the case that very day and fined Misch $100 and costs, and the Federal detective wrapped up his investigation.
