Was a heavy drinker and often found himself in financial difficulties due to heavy gambling debts. Was approached one evening in a tavern by a KGB agent who offered to by him a drink. Nelson Cornelius Drummond accepted and the agent continued buying drinks all night. The agent later asked the drunken Drummond if he would obtain a Naval identification card for the agent, for use at the Naval Exchange store. Drummond agreed and accepted $250 for his efforts, signing a receipt slip for having received the cash.
Drummond was immediately blackmailed, with the KGB threatening to show the receipt to Naval authorities if he refused to cooperate in turning over documents to them. Drummond did as the demanded, supplying the Russians with sensitive documents in return for payments of cash.

The FBI received the information but didn’t want to blow Polyakov’s covers so they set up surveillance on Drummond and ended up following on trips to New York. He returned from these trips flush with cash. Drummond was seized by FBI agents outside of a diner in Larchmont, NY in which he had met with a Soviet United Nations Delegates Evgeni Prokhorav and Ivan Vyrodov. Authorities discovered 11 classified documents and a miniature camera concealed in the trunk of Drummond’s car. Drummond made a full confession, estimating that he had receive upwards of $20,000 over the period of time. His activities cost the United States more than $200 million, the cost of replacing and revising the documents, manuals and plans he had turned over to the KGB.
