The Southern Jordan Valley District had witnessed military operations during the 1948 war, and also during the Battle of Al-Karama 1968 AD, and the names of the martyrs here are included in their chapters. But there is also a squad of martyrs who died while performing a humanitarian duty in clearing minefields to prepare the infrastructure for the potash plants. The Potash Company has erected a memorial edifice for them in Gawr As-Safi in the form of opposite chordal arcs with interspaces that almost meet at the top with the interference of light through them. The main eastern facade bore the names of the martyrs, both civilians and soldiers. The oppositeness of the seven chords on each side opens towards the west, and each chord is half a crescent on its ninth day, suggesting that the martyrs are of light, and that the direction of the chords towards the major project that was accomplished thanks to the men of the Royal Jordanian Engineering Corps, of whom 20 were martyred, and also thanks to a number of employees at the company.
