In the summer of 1991, US Army Colonel James Cox arrived in Moscow, the capital of the Soviet Union, to serve as Assistant Army Attaché. Little did he know that Communist hardliners were about to launch a coup. When the coup started, the intelligence agencies in Washington immediately needed up-to-the-minute information on developments, so the attachés went out on the streets to get it. Hear Colonel Cox tell SPY Historian Mark Stout what it was like chasing tanks on the streets of Moscow and witnessing Boris Yeltsin make his stand at the Russian White House.
