In the early days of the State of Israel, Hillel El-Dag (originally Oldak) worked as an engineer for the Solel Boneh company in the construction of the Ramla bypass road, between Hulda and Masmiya in central Israel. One morning, when El-Dag arrived at the work site, he was surprised to find that his tractors had disappeared. Concerned at this turn of affairs, El-Dag rushed to neighboring Kibbutz Na’an, in the hope that someone there might know what happened to the expensive tractors. There, resting on the grass, he met a group of soldiers, including Givati Brigade Deputy Commander Meir’ke Davidson. After El-Dag introduced himself and asked whether they knew what had happened to his tractors, the deputy commander turned to him with a question of his own:
“Are you an engineer?” he asked immediately.
“Yes,” I answered
“Very well, consider yourself enlisted. We need an engineer for Givati [the IDF brigade].”
(from the book History of the Engineering Corps [Hebrew])
Among the many things that the young, new army required upon its establishment, there was an urgent need for experienced and professional engineering personnel. Finding suitable people was no simple matter, and the Israeli army searched for them under every nook, cranny… and tractor. As it turned out, Col. (Res.) El-Dag remained in the Engineering Corps, advanced up the chain of command, and eventually even served as Chief Engineering Officer between 1958 and 1964.
Engineering since the dawn of history
The first known fortifications in the world can actually be found within the borders of the Land of Israel; they were built in Jericho in the seventh millennium BCE. Engineering has been necessary in every place and in every period as a means of both defense and attack. Our ancestors used engineering to figure out how best to impose an effective siege, and how to defend against a siege that was imposed on them. The renewed Jewish settlement in the Land of Israel needed solutions to protect itself from hostile activity by local Arabs and their allies. The laws of the British Mandate forbade Jews from carrying weapons, so the engineers from the Jewish underground organizations established hidden caches of weapons in kibbutzim and border communities (such a hiding place was called a slik in Hebrew). These arms caches proved essential ahead of the establishment of the State of Israel.
The first engineers to seriously dedicate themselves to the issue of how to properly protect the Jewish communities of Mandatory Palestine joined together in 1934, when the technical department of the Haganah was established. They were occupied with planning and constructing fortifications for the border settlements and within cities that had mixed Jewish-Arab populations, with the bulk of their efforts focused on establishing the “Tower and Stockade” settlements in the years 1936-1939. This was a large-scale engineering-military-settlement operation to capture strategic points throughout the country on which settlements could be established. The Haganah’s technical department played a critical role in planning the complex operation, in a way that would be effective, applicable, and safe. All the materials were prepared ahead of time. Along with a wooden tower, a barrier was built to surround the settlement. This barrier was made of two parallel wooden walls with gravel filling the gap between them. These fortifications would typically be erected within a single day. This is how the kibbutzim Nir David, Hanita, Sha’ar HaGolan, Dan, Dafna and a total of over 50 settlements were established.
The first missions which were carried out by the underground organizations and which required advanced military-engineering knowledge took place shortly before the War of Independence. They included the Palmach’s bombing of strategic bridges on the “Night of the Bridges” in June 1946, and the Irgun’s bombing of a wing of the King David Hotel in Jerusalem. Many who would later become IDF engineers gained their experience within the British Army’s Jewish Brigade. Among them was Emmanuel Shahar, who would become the first commander of the Combat Engineering Corps upon the establishment of the Israel Defense Forces.
Two tents and an old building housed the first IDF engineering school in the Jalil area – today’s Glilot, just north of Tel Aviv, which was established a few months after the beginning of the War of Independence to quickly train people in the engineering professions. Conditions were not promising, to say the least. Studies were initially offered in two languages: Hebrew and Yiddish. The few instructors were often borrowed by the fighting forces. In the small school that housed 30 students in total, there were hardly any explosives, let alone written material.
During one training session dedicated to explosives, a trainee lit a delay fuse that was attached to a bomb. The trainee was gripped with fear and was unable to throw the explosive away quickly enough. Due to this moment of hesitation, peoples’ lives were suddenly in danger. Luckily, the instructor, Yossi Ben Hurin, jumped on the trainee and managed to quickly throw the explosive away from the area. The trainee was unharmed, but Ben Hurin was injured by shrapnel. This accident inspired the immortal slogan that accompanies the IDF’s Combat Engineering Corps to this day, coined by Eliezer Meron, the school’s first commander: “A sapper makes a mistake only once in his life.”
Since it was very difficult to obtain proper engineering equipment, the majority was improvised in the field. The corps members used resourcefulness, ingenuity, and whatever the British left behind, as well as equipment from large construction companies, contractors, kibbutzim, or private individuals. The shortage of mines led to the invention of dummy mines, and later also to the use of dummy tanks and dummy cannons that were activated remotely. These “fake” mines and tanks were convincing enough to require enemy forces to expend resources on removing the perceived threat. Such inventions helped the IDF cope with its own equipment shortages.
Improvisation is the name of the game
The Combat Engineering Corps has not always received the recognition it deserves, even though its importance on the battlefield is enormous. On the morning of May 15th, the day after the declaration of the State of Israel, there was serious concern over a coordinated invasion by seven armies into Israel’s territory, casting a shadow over the leaders of the new state. Major General Yochanan Ratner, head of the IDF’s Planning Directorate, entered the room and said:
“The key to stopping the seven armies is in the hands of the Engineering Corps.”
The engineering personnel promised to do everything in their power to prevent Israel from needing to face seven fronts at once. Blowing up bridges over the Jordan River was one of the first and most critical actions taken by the Combat Engineering Corps at that time, as it helped prevent the Jordanian army from invading the settlements in the Jordan Valley and Beit She’an Valley. On the southern front, mines were effective in holding back the Egyptian army.
Later, breaking through Burma Road to besieged Jerusalem, the Engineering Corps played a critical role in paving the way to the capital. Equipment shortages meant that the soldiers sometimes had to work with their bare hands. The operation was completed at the very last moment, just before the first temporary truce between Israel and the Arab countries came into effect. On a part of the road, between Givat Shaul and Motza, the engineers even made use of some physical features of an ancient Roman road which passed through the area. Breaking through to the city with this road offered a lifeline for the blockaded residents of Jerusalem and a tremendous morale boost for the Jewish population which was fighting for its life.
The members of the Engineering Corps created roads wherever they were needed. The harsh battles and the pressing deadlines sometimes demanded unbelievable ingenuity, like on the eve of Operation Horev, when military forces needed to get from Be’er Sheva to Gaza, but their path was blocked: Heavy rain from late-December 1948 had turned the desert’s loess soil into muddy quicksand. For four days and nights, the crews of the Engineering Corps worked on preparing a road for safe passage of the battalions. They used whatever they could find – nets, cans, cypress trunks, and even coats spread along the road – to ensure that the wheels of the heavy trucks wouldn’t get stuck in the mud. All this was done in order to enable the IDF forces to pass through and reach their destination. At the end of the operation, Yigal Alon, who had commanded the southern front, sent a letter of appreciation to the commander of the Engineering Corps for his men’s hard work and dedication. Since that day, the Engineering Corps has always worked closely with the initial breakthrough force in every war and major operation the IDF has undertaken. No commander wants to enter unfamiliar territory without an engineering team close by to help pave the way and clear any possible threats.
Saluting the mines
Much is often left unsaid about the IDF’s Combat Engineering Corps. Many are simply unaware of the incredible responsibilities these soldiers undertake, as well as the changing nature of their roles, and their critical contribution to the war effort in all of the country’s major conflicts. Engineering personnel are at the forefront of any major military force. No infantry or armored division commander is willing to move without them. Their professionalism and experience in breaking through roads and eliminating risks are irreplaceable.
This is a small and professional corps, whose various units are always busy – in times of war as well as times of relative quiet. Their areas of responsibility include, among others, explosives, mining and clearing mines, breaking through obstacles, blocking roads, preparing fortifications, building and demolishing bridges, and operating heavy engineering equipment. The corps includes three regular battalions: Asaf, Lahav and Machatz, and the special unit Yahalom (the elite engineering unit used for special operations).
The challenges facing the Engineering Corps are constantly changing. During the Yom Kippur War, it was tasked with facilitating the Suez Canal crossing. When the IDF was operating in Lebanon, its engineers had to cope with a massive amount of improvised explosive devices. More recently, the Engineering Corps have been focused on providing advanced solutions for uncovering and demolishing tunnels.
On October 7, reservists from the Engineering Corps were called up to serve, and they have been working tirelessly in all the sectors ever since, especially in providing unique engineering solutions for the units operating in the Gaza Strip.
Soldiers from the Engineering Corps are combat warriors in every sense of the word, who are highly specialized in the following spheres:
“You need to be a soldier who uses your head all the time: where is the smartest place to plant a mine, a charge or a demolition block?” Matan, a reservist in the Combat Engineering Corps, explains. “You have to understand that the Engineering Corps maintains such a high level of operational preparedness, and the changes and adjustments are so frequent that if I need to miss one drill in the reserves, it is immediately noticeable and I need to work twice as hard during the next drill to maintain my level of competence.”
Along with the obvious risks, he says, serving in the Engineering Corps has clear advantages: “The risk in our work is so high that it creates friends for life. We have to trust each other a thousand percent.” These conditions mean that combat engineering soldiers must heavily consider the risks they face every time they are called on to dismantle a charge. As an engineering officer who identified himself as Ori said in an interview in 1969: “To this day, I salute every mine before I approach it.”
