Isolation At 1:55 p.m., just before the start of the war, a reconnaissance force swam to the east bank of the
Suez Canal, two kilometers south of Fort Lahtzanit, and laid two ropes across the canal to facilitate the crossing of friendly forces. At 2:05 p.m., as
Operation Badr began, an artillery barrage was initiated against the fort using just the 85 mm guns and
B-10 recoilless rifles of the brigade's anti-tank company; the use of high trajectory artillery guns was forbidden since a number of Egyptian aircraft were flying over this area. The troops tasked with isolating Fort Lahtzanit began crossing the canal in dinghies at 2:15 p.m.. Ten minutes later they reached the east bank and proceeded to climb the sand wall. They succeeded in attracting Israeli fire, thereby facilitating the main assault force in its mission to attack the fort later on. The troops tasked with isolating the fort from the east reached and occupied a firing ramp prepared for tanks, and raised the Egyptian flag over it. This severely demoralized the Israeli soldiers inside Fort Lahtzanit. Soon after the Sa'iqa company (less one platoon) arrived at the firing ramp as well. A reserve of eight
M48 Patton tanks were pushed forward to reinforce the fort. They came up against the eastern isolation force, which destroyed one of the tanks at a range of . Another tank broke through the Egyptian position and proceeded immediately north towards Fort Orkal, but was destroyed at Kilometer 14 by the northern isolation force. The remaining tanks retreated eastwards to Baluza.
Attack At around 2:50 p.m., the B-10 rifles on the west bank managed to open a breach in the barbed wire surrounding the fort, and also destroyed other significant targets, such as the observation equipment. Meanwhile,
combat engineers were breaching further openings using
Bangalore torpedoes, under heavy
small arms fire and
hand grenades. The battalion's main assault force was crossing at the same time. The main assault force then funneled through the breaches and entered the Israeli trenches. The Israeli command in Northern Sinai kept receiving frantic calls for help from the fort's radio operator, and gunfire could also be heard. The Egyptians captured the southern sector of the fort by 3:05 p.m.. Five minutes later, the assault force moved against the northern sector of the fort. Within fifteen minutes, the Egyptians were in control of the fort. The power generator inside the fort was destroyed, and all electricity and communication lines leading to the fort were severed. At 3:30 p.m., Maj. Gen. Khaled was informed that Lahtzanit had been seized and that Israeli soldiers had been captured. The Egyptians proceeded to clear the bunkers. They utilized
flamethrower teams, which had a visible psychological impact on the fort's garrison. At one point, the Egyptians, with the help of a wounded Israeli prisoner, managed to secure a bunker by convincing the panicked Israelis inside to come out and surrender. Soon after losing contact with the fort, the Israelis attempted to reach it once more. By this time, Malhov was dead. A group of tanks from Baluza advanced to Lahtzanit, but the Sa'iqa company occupying the firing ramp managed to destroy two tanks, forcing the remainder to retreat. Another group of tanks and half-tracks tried to break through the southern isolation force, but were ambushed and withdrew after losing a tank. At 4:00 p.m., two anti-tank teams joined the Sa'iqa company on the firing ramp. Both teams, along with the company, were ordered to advance eastward and seize the crossroads. At around 5:00 p.m., the
Israeli Air Force began attacking Egyptian forces in the fort and on the west bank of the canal. One group of four aircraft attempted to bomb the fort; the first aircraft dropped its payload of seven bombs, then descended to a low altitude to escape anti-aircraft fire. An anti-air platoon at the Kilometer 17 mark soon shot down an Israeli aircraft (either a
Mirage III or an
A-4 Skyhawk) with a
Strela 2 missile, destroying it. Between 6:00 and 7:00 p.m. all bunkers and troop shelters inside the fort were cleared, and the Egyptians transferred 26 Israeli prisoners to the west bank of the canal, and thereafter transferred them to Port Said for intelligence gathering. The Israelis concentrated heavy artillery fire against the fort, once they were sure it had been captured by the Egyptians. At 9:30 p.m., the Sa'iqa company reported an Israeli armored column advancing towards the fort. Two Egyptian tanks on the west bank opened fire, forcing the Israeli tanks and armored vehicles to withdraw. The company continued eastwards, eventually reaching the crossroads, facing no resistance along the way. With the reinforcing anti-tank teams, the company established defensive positions, and el-'Abassi dispatched patrols to secure the roads leading to the fort. ==Aftermath==
