It was an unimaginable act of terrorism that took the lives of 16 Alexandria residents on Sept. 11, 2001. The City of Alexandria will mark the 22nd anniversary of what remains the worst terrorist attack in U.S. history with a ceremony remembering those who were killed and honoring the first responders who answered the call.

The event, which is open to the public, will take place in Market Square in front of City Hall at 10 a.m. on Monday, Sept. 11. The ceremony will remember those killed, those who survived, and all who were affected. A “Return to Quarters” bell-ringing ceremony will honor each of the victims.

Penn-Daw Station 11 firefighter Jim Morris, now retired, was one of the first responders pictured atop the Pentagon in the now iconic photograph of the American flag as it was unfurled. As he participated in the recovery efforts in Arlington, his mind was 225 miles north in New York City, where his brother Seth was still unaccounted for in the rubble of the World Trade Center.

Seth Morris was a broker with Cantor Fitzgerald working on the 105th floor of World Trade Center One. He did not survive.

The coordinated attacks at the Pentagon, World Trade Center and outside Shanksville, Pa., resulted in 2,977 deaths. Remains of more than 1,700 of those who perished have never been recovered, although they are included in the 2,977.
