Lemar ordered Adams to investigate Hill 409, the site of the smuggling, with a squad. They were ambushed, and only Adams and his friend Lt. Yarrow escaped, the latter barely. Adams was certain Lemar had set him up, and confronted him about it.[3] Minutes later, Adams was knocked out by a poison. Enos Polk killed Lemar with Adams's knife, and "arrived" moments later to arrest Adams for the crime. It had all been planned by Yarrow, who actually acted as the leader of the smuggling ring. Captain Adams was brought before court-martial, where he was defended by Yarrow. Adams claimed that he blacked out, and was possibly drugged, but there was no evidence for that story.
