<P> The Honduran air force reacted by striking the Salvadoran Ilopango airbase . Honduran bombers attacked for the first time in the morning of July 16 . When the bombs began to fall, Salvadoran anti-air artillery starting firing, repelling some of the bombers . The bombers had orders to attack the Acajutla Port, where the main oil facilities of El Salvador were based . Honduran air - raid targets also included minor oil facilities such as the ones in Cutuco (es; ceb). By the evening of July 16, huge pillars of smoke arose in the Salvadoran coastline from the burning oil depots that had been bombed . The effectiveness of the attack on Ilopango has been called into question but it is generally accepted that the bombing of oil facilities and depots severely disrupted the logistics of the Salvadoran army . </P> <P> Nicaraguan dictator Anastasio Somoza Debayle helped Honduras by providing weapons and ammunition . </P> <P> The Honduran government called on the OAS to intervene, fearing that the nearing Salvadoran Army would invade the capital Tegucigalpa . The OAS met in an urgent session on 15 July and called for an immediate cease - fire and a withdrawal of El Salvador's forces from Honduras . El Salvador resisted the pressures from the OAS for several days, demanding that Honduras first agree to pay reparations for the attacks on Salvadoran citizens and guarantee the safety of those Salvadorans remaining in Honduras . A cease - fire was arranged on the night of 18 July; it took full effect only on 20 July . El Salvador continued until 29 July to resist pressures to withdraw its troops . Then a combination of pressures led El Salvador to agree to a withdrawal in the first days of August . Those persuasive pressures included the possibility of OAS economic sanctions against El Salvador and the dispatch of OAS observers to Honduras to oversee the security of Salvadorans remaining in that country . The actual war had lasted just over four days, but it would take more than a decade to arrive at a final peace settlement . </P> <P> El Salvador finally withdrew its troops on 2 August 1969 . On that date, Honduras guaranteed Salvadoran President Fidel Sanchez Hernandez that the Honduran government would provide adequate safety for the Salvadorans still living in Honduras . Sanchez had also asked that reparations be paid to the Salvadoran citizens as well, but that was never accepted by Hondurans . There were also heavy pressures from the OAS and the debilitating repercussions that would take place if El Salvador continued to resist withdrawing their troops from Honduras . </P>
