[3] In 1941 he joined the "Jewish Settlement Police", and the following year completed an infantry officers' course at the training school for Haganah cadres.

In 1946 he became a district officer for the Haganah Intelligence Service (SHAI), based in Petah Tikva, with responsibility for the southern region.

On 20 June 1948 he took part in the field drumhead court-martial and wrongful execution of Meir Tobianski at Beit Jiz.

The attacks were to be blamed on the Muslim Brotherhood, Egyptian Communists, "unspecified malcontents" or "local nationalists" with the aim of creating a climate of sufficient violence and instability to induce the British government to retain its occupying troops in Egypt's Suez Canal zone.
