Twenty-one-year-old Lieutenant Greengold was home on leave when Egypt and Syria launched a coordinated surprise attack on two fronts. He was not attached to any unit as he was about to take a course for company commanders. Once he realized war had broken out, he hitchhiked to Nafekh, a command center and important crossroads in the Golan Heights, where he initially helped with the wounded, as no tanks were available. When two damaged Centurion tanks were repaired, Greengold was put in charge of them and, at 2100 hours, was ordered to take hastily assembled scratch crews down the Tapline Road.
