Blockade

"During the summer and fall of 1971, the U.S. government supported the Pakistani military dictatorship while it massacred the people of East Bengal. But a group of Americans challenged this policy, tied up East Coast ports to Pakistani shipping, and had a major influence on changing U.S. policy. Blockade is the story of the ""non-violent fleet"" of canoes and kayaks that attempted to turn around the U.S. govenment."
