AMBUSH AT CENTRAL PARK: When the IRA Came to New York

In 1922, three of the Irish Republican Army's top gunmen arrived in New York City seeking vengeance. Their target: "Cruxy" O'Connor, a young Irishman who kept switching sides as revolution swept his country in the wake of WWI. Six of his IRA comrades were killed when he told police of their safe house. A year later, the IRA gunned him down in a hail of bullets in New York City. Photos.
