American Experience: Two Days in October

Monday at 9 p.m. on MPT, 10 p.m. on WETA

In October 1967, an entire battalion of American soldiers was nearly wiped out by Viet Cong forces. Meanwhile, in Madison, Wis., hundreds of college students staged a peaceful protest against napalm maker Dow Chemical Co.

Thirty-five people were hospitalized with injuries, marking the first time an anti-war protest had turned violent.

The documentary, which revisits that fateful month, is based on the book "They Marched Into Sunlight," published in 2003 by Washington Post associate editor David Maraniss. The film includes interviews with survivors of the Vietnam attack and participants in the campus protest.
