In 1989, the FMLN made a mighty push for power, putting forward bold new peace proposals while simultaneously preparing a military campaign with the potential to force an end to the war. On October 31, right-wing death squads bombed the headquarters of FENASTRAS, a militant labor federation, killing 10 people. The FMLN broke off stalemated peace talks and launched the largest offensive of the war.
The offensive, and the governmentâ€™s brutal response, changed the course of the war. The FMLN occupied parts of San Salvador for weeks, at one point trapping a group of U.S. Green Berets inside the Sheraton Hotel in one of San Salvadorâ€™s most exclusive neighborhoods. By bringing the war to the doorsteps of the rich, the FMLN convinced the Salvadoran and U.S. governments that the revolution could not be defeated militarily.
