At the "Hanoi Hilton", POWs cheered the resumed bombing of North Vietnam starting in April 1972, whose targets included the Hanoi area. The old-time POWs cheered even more during the intense "Christmas Bombing" campaign of December 1972, when Hanoi was subjected for the first time to repeated B-52 Stratofortress raids. Although its explosions lit the night sky and shook the walls of the camp, scaring some of the newer POWs, most saw it as a forceful measure to compel North Vietnam to finally come to terms.
