On Saturday night, 15 May, the observation posts reported many vehicles with full lights moving along the Golan ridge east of the Sea of Galilee.
Degania Alef After the fall of Tzemah, the Haganah command realized the importance of the campaign in the region, and made a clear separation between the Kinarot Valley, and the
Battle of Gesher fought against Transjordan and Iraq to the south. On 18 May,
Moshe Dayan, who had been born in Degania, was given command of all forces in the area, after having been charged with creating a commando battalion in the
8th Brigade just a day before. A company of reinforcements from the
Gadna program was allocated, along with 3
PIATs. Other reinforcements came in the form of a company from the
Yiftach Brigade and another company of paramilitaries from villages in the
Lower Galilee and the
Jezreel Valley. The Israeli defenders called the reinforcements assuming they were facing the main Syrian thrust. The Syrians were not intending to carry out any further operation south of the Sea of Galilee and planned to make their main effort further north, near the Bnot Ya'akov bridge. On 19 May, the Iraqis were about to drive west through
Nablus toward
Tulkarm, and asked the Syrians to make a diversion in the Degania area to protect their right flank. The Syrians complied, their main objective being to seize the bridge across the river north of Degania Alef, thus blocking any Israeli attack from
Tiberias against the Iraqi line of communications. Heavy Syrian shelling of Degania Alef started at about 04:00 on 20 May from the Samakh police station, by means of 75 mm cannons, and 60 and 81 mm mortars. The barrage lasted about half an hour. At 04:30 on 20 May, the Syrian army began its advance on the Deganias and the bridge over the Jordan River north of Degania Alef. Unlike the attack on Samakh (Tzemah), this action saw the participation of nearly all of the Syrian forces stationed at Tel al-Qasr, including infantry, armor and artillery. The Israeli defenders numbered about 70 persons (67 according to Aharon Israeli's head count), most of them not regular fighters, with some Haganah and Palmach members. Their orders were to fight to the death. They had support from three 20 mm guns at
Beit Yerah, deployed along the road from Samakh to Degania Alef. They also had a
Davidka mortar, which exploded during the battle, and a PIAT with fifteen projectiles. At night, a Syrian expeditionary force had attempted to infiltrate Degania Bet, but was caught and warded off, which caused the main Syrian force to attack
Degania Alef first. At 06:00, the Syrians started a frontal armored attack, consisting of 5 tanks, a number of armored vehicles and an infantry company. The Syrians pierced the Israeli defense, but their infantry was at some distance behind the tanks. The Israelis knocked out four Syrian tanks and four armored cars with 20 mm cannons, PIATs and
Molotov cocktails. Meanwhile, other defenders kept small arms fire on the Syrian infantry, who stopped in citrus groves a few hundred meters from the settlements. The surviving Syrian tanks withdrew back to the Golan. At 07:45, the Syrians halted their assault and dug in, still holding most of the territory between Degania Alef's fence and Samakh's police fort. They left behind a number of lightly damaged or otherwise inoperable tanks that the Israelis later managed to repair.
Degania Bet Despite the Syrian superiority in numbers and equipment, the destruction of a multitude of armored vehicles and the infantry's failure to infiltrate Degania Alef was the likely cause for the retreat of the main Syrian force to Samakh (Tzemah). A less-organized and sparsely numbered armored and infantry force forked off to attack
Degania Bet. Eight tanks, supported by mortar fire, moved within 400 yards of the settlement defense, where they stopped to provide fire support for an infantry attack. The Syrians made two failed attempts to breach the Israeli small arms fire defense and gave up the attempt. Against this force, the Israelis had about 80 people and one
PIAT. The defenses in Degania Bet were disorganized and there were not enough trenches. They also had no communication link to the command, so Moshe Dayan sent one of his company commanders to assess the situation. While the battle was taking place, the
65 mm artillery, four
Napoleonchik canons, reached the front in the middle of the day and were placed on the Poria–Alumot
ridge. It was the first Israeli artillery to be used in the war. At 13:20, they began to fire at the Syrians, and after about 40 rounds the latter began to retreat. The Israelis also fired into Samakh, where the Syrian officers, who had until then believed that the Israelis had nothing that could hit their headquarters, took shelter. One projectile hit the Syrian ammunition depot in the village, and others ignited fires in the dry fields. While the soldiers who operated the cannons (still lacking sights) were not proficient in handling them, an acceptable level of accuracy was achieved after practice shots into the Sea of Galilee. In all, the artillery fire took the Syrian army by complete surprise, and the latter decided to regroup and retreat to
Tel al-Qasr, also recalling the company at Sha'ar HaGolan and Masada. A total of 500 shells were fired by the Israeli artillery. Syrian officers may have shot some of their fleeing soldiers. There were two other reasons for the Syrian withdrawal. The 3rd Battalion from the Palmach's Yiftach Brigade had been sent by boat during the previous night across the sea to Ein Gev, planning to assault and capture
Kafr Harib. It was noticed and shelled by the Syrians, but one of the companies managed to climb up the Golan. It carried out a smaller raid at dawn, bombing water carriers and threatening the Syrian 1st Brigade's line of communications. The second reason was that they were running out of ammunition:
Husni al-Za'im had been promised replenishment, and attacked Degania short of ammunition. Za'im ordered a withdrawal when his troops ran out of ammunition. The replenishment was instead sent to the 2nd Brigade further north. The Israelis were not aware of this, and attributed the Syrian withdrawal to surprise at the Israeli artillery fire. ==Aftermath and effects==
