The Ibdis military post is located on a ridge about 2 km. northeast of Negba.
The village of Ibdis, which was about 600 m. southeast of the military post, was part of an Egyptian stronghold which was taken by the Egyptian army in June 1948.
The village was destroyed in July 1948. The Egyptian army took up position in the village and surrounding positions, and laid siege to the forces defending Kibbutz Negba.
Ibdis is an important position in plains traversed by the Lakhish riverbed, north of Kibbutz Negba and the Iraq Suidan police station. West of the village, halfway between it and the route from the Julis camp to Negba, are the hills which in the War of Independence were called the Ibdis Positions, whose peak affords an expansive view of the whole region.
Between July 7 and July 10 1948 fierce battles took place for the Ibdis position. Regiments 52, 53 and 54 of the Givati Brigade took part in the fighting. They fought heroically and, in the An-Far (Operation) An-Far the position was taken and the Giv'ati forces continued to hold the position against the Egyptian counterattack.
The battle for Ibdis was one of the fiercest of the whole of the War of Independence. It was here that the Egyptian army was stopped, at a heavy price, and Negba was not cut off.
