The intent was to destroy all major target complexes in the Hanoi and Haiphong areas, using an all-weather force of heavy B-52s and smaller F-111 attack aircraft by night while tactical aircraft would continue to press daytime attacks. <br /><br />The campaign unfolded over the 12-day period of December 18-29, 1972. After 11 days of bombing, Hanoi was ready for peace negotiations.
