April 21, 1967, at the height of the escalation of the Vietnam war, the US Marine Corps had set up a recruiting desk in Hartley Hall, the dormitory adjacent to Hamilton Hall seen here in the background. I'm in there somewhere. "The largest demonstration at Columbia in thirty years [i.e. before World War II] occurred Friday (April 21) ... More than eight hundred supporters of Students for a Democratic Society marched for one and a half hours in a well-organized picket line around Van Am Quadrangle, as five hundred bystanders and hecklers glared and jeered from behind a hedge several feet away on south field ... the anti-SDS faction threw more than half a dozen eggs at the protestors ... Sporadic outbreaks of violence marked the second day of massive student demonstrations ... The Marines recruited from 10 a.m. to 2 p.m., as had been scheduled, and then slipped out through the side door of Hartley Hall." —Columbia Daily Spectator, Volume CXI, Number 101, 24 April 1967.
