Attack At the Nahal Oz base Hamas'
Al-Qassam Brigades were joined by
Palestinian Islamic Jihad's
Saraya Al-Quds, On 7 October 2023, at 6:31a.m., Israeli field surveillance soldiers from Nahal Oz spotted two Hamas squads planting explosives at the
Gaza–Israel barrier while on patrol. The bombs were detonated at two areas on a newly constructed
barbed wire fence. Two soldiers from the
Golani Brigade's 13th Battalion rushed to provide backup for the lone soldier guarding the base. At 6:38 and 6:41, two breaches were created in the Gaza–Israel barrier near the base, and dozens of militants on motorbikes, pickup trucks, and on foot stormed into Israel. Militants reached the base's perimeter wall at 6:45, while the Golani soldiers, who were under-equipped, began deploying to guard posts on the western side of the base. An officer in the base's
command center activated a remotely-operated gun system to shoot at the militants as they headed towards the base, but as militants shot the surveillance cameras the monitoring screens in the command center began to go dark. A tank stationed in the base attempted to position itself to overlook the border, but by then a wave of 65 militants had arrived. While battling soldiers inside the base, militants fired into holes in the base's walls, critically injuring the 13th Battalion's deputy commander. Between 6:48 and 6:56, the militants exchanged fire with soldiers in the base.
RPGs were launched at the perimeter wall and the guard posts came under massive fire. At 7:05, the first militants entered the base. At 7:09, the surveillance soldiers left their stations and went to hide in the command center. At 7:30, militants who were on the eastern side flanked around it and reached the entrance, where they engaged in a lengthy exchange of fire with the three soldiers guarding it, killing them after losing several of their own. They then went inside, and soon destroyed a large part of the post and equipment within it. The soldiers at the post were surprised, and most of them were killed. Meanwhile,
Israeli Air Force drones and attack helicopters began arriving at the base at 7:30 and circled over it as the pilots and drone operators struggled to differentiate between IDF soldiers and Hamas militants, with the first drone strike carried out at 7:50. Throughout the rest of the battle numerous air and artillery strikes would subsequently be carried out inside or near the Nahal Oz outpost. The base was the site of the largest number of airstrikes in the battles of October 7 due to the presence of numerous soldiers directing them. Ultimately, 14 drone strikes and 6 helicopter strikes were carried out inside the base, and 150 helicopter cannon rounds were fired into the base. Another 77 drone strikes, 36 helicopter strikes, and 10 airstrikes by fighter jets were carried out near the base, with 1,600 artillery shells also fired at the vicinity of the base. The militants threw a smoke grenade and two fragmentation grenades into the shelter. Fourteen of the soldiers, all of whom were injured to various degrees and four of whom were armed, fled the shelter. One was killed while running away and two took shelter in the base's clinic, where they were later killed when militants threw grenades into it. The remaining eleven barricaded themselves inside a room which militants then tried to enter before being dispersed by a drone strike. The drone operator was not sure of the identities of the militants and carried out the strike near them, causing them to flee. Militants also continued to try to break into the shelter with the rest of the soldiers remaining inside. One of the armed soldiers remaining in the shelter, Captain Eden Nimri, positioned herself at one of the two entrances to the shelter. She opened fire on the first militant to enter but more followed and Nimri was killed after running out of ammunition. Another of the armed soldiers, Sergeant Shai Biton, also managed to kill a militant before she was also killed. As of 13 December 2023, the IDF investigation could not yet pinpoint the exact type of chemicals used. and seven female observers. Soldiers of the
Paratroopers Brigade's 890th Battalion, who had been fighting at
Be'eri and
Kfar Aza, headed towards the base after being called in as reinforcements. They were joined by other paratroopers, a number of
Golani Brigade officers, and members of the
Israel Police's
Yamam counter-terrorism unit. The reinforcements arrived at the base at 1:36p.m. and began clearing it of militants. By 5:00, the base was completely cleared. Of the latter,
one was killed in captivity, one
was rescued by an IDF raid a few weeks later, and five were released during the
January 2025 Gaza war ceasefire after spending more than 470 days in captivity. In addition to the seven Unit 414 female observers, three tank crew, two of them dead, were also taken to Gaza; they were returned in October 2025 as part of the
Gaza peace plan. Parents of the 18 and 19-year-old girls from the unarmed surveillance unit felt that their daughters had been abandoned by the armed officers. The surveillance buildings at Nahal Oz and their computer equipment were destroyed within the first hour of the invasion. == Inside the kibbutz ==
