U.S. Aircraft Begin to Mine North Vietnamese Ports
May 9, 1972
In retaliation for the North Vietnamese Easter Offensive, President Nixon orders U.S. aviators flying A-7 Corsairs and A-6 Intruders from the carrier USS Coral Sea to begin mining the waters surrounding North Vietnamese seaports, including the vital port of Haiphong. Over 85 percent of the North’s military supplies flow through these ports, and the mines are intended to interdict the materiel powering the Communist offensive. The mining is labeled Operation POCKET MONEY.1
