The Indo-Irish-German alliance and the conspiracy were the target of a worldwide British intelligence effort , which was successful in preventing further attempts . American intelligence agencies arrested key figures in the aftermath of the Annie Larsen affair in 1917 . The conspiracy led to criminal conspiracy trials like the Lahore Conspiracy Case trial in India and the Hindu – German Conspiracy Trial in the United States , the latter being the longest and most expensive trial in the country at that date
