“Last Friday together with Etzel” – the acronym for the National Military Organization, also known as the Irgun, another pre-state underground militia, led by Menachem Begin – “our movement carried out a tremendous operation to occupy the Arab village on the Jerusalem-Tel Aviv road – Deir Yassin. I participated in this operation in the most active way,” wrote Yehuda Feder, whose nom de guerre in Lehi (also known as the Stern Gang) was “Giora.”
Further along in the letter, he describes in detail his part in the massacre that took place there. “This was the first time in my life that at my hands and before my eyes Arabs fell. In the village I killed an armed Arab man and two Arab girls of 16 or 17 who were helping the Arab who was shooting. I stood them against a wall and blasted them with two rounds from the Tommy gun,” he wrote, describing how he carried out the execution of the girls with a submachine gun.
