  • In WW1:
    • Germans deliberately infected Russian horses on the Ostfront, as well as French cavalry.
    • “At that time, Anton Dilger lived in Germany, but in 1915 he was sent to the [US] carrying cultures of glanders...set up a laboratory in his home in…Maryland. He used [dockworkers] in Baltimore to infect horses with glanders while they were waiting to be shipped to Britain. Dilger was under suspicion as being a German agent, but was never arrested”
