On June 17, Kerling's team landed from "U-584" at Ponte Vedra Beach, south-east of Jacksonville, Florida. They were ordered to place mines in four areas: the Pennsylvania Railroad in Newark, New Jersey; canal sluices in both St. Louis, Missouri, and Cincinnati, Ohio; and New York City's water supply pipes. The team members made their way to Cincinnati and then split up, two going to Chicago, Illinois, and the others to New York. Dasch's confession led to the arrest of all of the men by July 10.
