About the same thing that happened to the Bonus Army.
A great find. I was searching for an example like what happened to the Bonus Army. Not being a history buff, my search only covered the deportations caused by the rise of illegal immigration. I can imagine the Great Depression world wide. There would have been a huge pressure for people in affected countries to do anything to get to America. I have a great Irish grandfather who stole away on a ship to get into America.
