On the morning of 7 October, at 6:30 AM local time, the Zikim training base was struck with what its commander called an "insane volley" of rockets, concurrent with the
heavy artillery barrages targeting
Sderot and other communities across the
Gaza envelope signaling the commencement of
Operation al-Aqsa Flood. In response to the surprise bombardment, new recruits on patrol duty at the base's perimeter fence were immediately sequestered in safe areas and replaced by junior officers by 6:36. The base's garrison began hearing gunfire from the direction of nearby military bases at 6:45. Al Qassam, the military wing of the Hamas movement, referred to the team who stormed the base as "Qassam naval commandos" . Observers at the Yiftach outpost witnessed dozens of Hamas fighters breaking through the
Gaza–Israel barrier, armed with
RPGs and driving motorcycles, trucks, and tractors towards their outpost. They arrived outside Yiftach's gate by 7:00, and Naama Boni, 19, the only sentinel, called for reinforcements. She was soon met by three young soldiers who rushed to the gate without uniforms and a member of the 13th Battalion of the
Golani Brigade who had been positioned in the
rear guard. The remainder of the garrison chose to shelter in place, and the five defenders were quickly overwhelmed by numerically superior Hamas forces and killed. Inside the outpost, two soldiers died and several were injured in intermittent clashes that lasted for twelve hours, though Hamas never breached the base's command post. Combat on the Zikim training base began at 7:30, when patrol teams at two separate locations spotted militants and reported incoming fire. The two highest-ranking officers on the training base at the time of the assault, company commander Capt. Adir Abudi, 23, and deputy company commander First Lt. Or Moses, 20, were killed in combat at "Position 6," where three other officers were wounded. A sentry post at the base's firing range was overrun once its defenders ran out of ammunition after 45 minutes of clashes; four officers were killed and two wounded in its defense. The fall of the firing range marked Hamas's first successful incursion into the training base, though they did not go on to attempt to take over other positions, which base commander Lt. Col. Shay ascribed to casualties and exhaustion. A single Hamas fighter managed to breach one of the "safe areas" where recruits were sheltering, killing an 18-year-old private who had been drafted two months prior before being killed by another recruit. Shay, who was at home in Sderot at the time of the attack, requested support from the nearby military bases, but realized that there was "no one to talk to" as they were also under assault. The other two bases in the area were eventually overrun amid serious losses of Israeli life. == Naval incursion and landing ==
