The leader of the right wing Zionists,
Ze'ev Jabotinsky, was ambivalent about reprisals on Arabs but, in response to terrorist attacks on Jews, the
Irgun launched a wave of retaliatory actions. These reached a crescendo on Sunday, 14 November 1937. As the Arab revolt wound down, Avraham Stern's faction diverged from the Irgun (which ceased operations during the war so as not to give any aid or comfort to Nazi Germany which it regarded as the greatest enemy of the
Jewish people) and led his group
Lehi on a campaign against Britain's rule. Stern leant heavily on examples from Jewish history such as the
Zealots and
Bar Kokhba, maintaining that heroism in the face of overwhelming odds would bring success. Opponents accused Stern of being overly influenced by
integral nationalism and naive about the danger posed by Nazism. Stern, meanwhile, regarded war between Western democracies and
Nazi Germany as "a conflict between
Gog and Magog". Lehi concentrated its armed struggle on the British with Stern claiming that they were the real "enemy" rather than Germany which was a "persecutor". Stern had very little support in the wider Jewish community for his violent campaign against the
British Mandate for Palestine. The investigation into the 11 April 1938 deaths of two British policemen killed by booby trap bombs planted on a train packed with Arabs found that Avraham Stern was behind the bombing. It was the first time Morton had heard the name. Morton became head of
CID in the Lyddal division covering Arab Jaffa and Jewish Tel Aviv. In one incident, he narrowly escaped death when his automatic pistol jammed during a gunfight with an Arab wanted for multiple murders, though he managed to shoot dead his opponent. Although he uncovered several large Jewish arms caches during two years in Lydda division, this had no effect on Stern's group. The austerely charismatic Stern, a poet and teacher who was referred to as "the light" by his followers, became ever more ruthless in his methods and mercilessly targeted Jewish members of the Palestine Police, regarding them as 'hirelings'. In November 1941 Ya'acov Soffioff, an off duty Jewish constable, was shot dead while walking with his wife and young daughter. The gunman was identified as Zelig Jacques, one of Stern's closest associates.
Yael Street bomb When his military chief of staff was arrested, Stern took personal charge of operations and ordered attacks on the CID officers who were arresting his men, namely Morton and his subordinate Tom Wilkin. To this end, on 20 January 1942, a multi-stage operation was mounted. Firstly, a small explosion created the impression that there had been an accidental explosion at a Lehi bomb factory; this lured members of the Palestine Police to a Tel Aviv apartment block on Ya'el street, where they were mistakenly identified by the watching Lehi operative as including the intended targets of Morton and Wilkin. Once the policeman were on the roof of 8 Ya'el, pre-placed explosives were electronically detonated from an overlooking vantage point. Deputy Superintendent Shlomo Schiff, one of the most senior Jewish policemen (whom Lehi had tried to kill in 1941) died instantly. Inspector Nathan Goldman died the day after. Inspector E. Turton, in his first day of a job in Tel Aviv and holder of the
King's Police Medal for Gallantry for saving a trainload of Jewish people from an Arab mob, had his legs amputated before dying a week later. Schiff and Goldman were due to testify against Stern gang members who had murdered two Jewish bystanders while robbing a bank official. Stern's men had also placed a third IED under the walkway to the building's entrance which was intended to target the senior officers arriving on the scene after Morton and Wilkin were killed. When Morton and Wilkin arrived in the aftermath of the rooftop bomb they were recognized by the man delegated to trigger the second IED but, contravening an order to trigger the explosion no matter how many bystanders would die, the Lehi operative did not detonate the walkway IED because of Jewish people nearby.
Morton's subsequent behavior when making arrests The bombing deaths of his colleagues demonstrated the Stern gang's thorough knowledge of police procedures, ingenuity in coming up with novel ploys, and mastery of improvised explosive devices. The knowledge that CID men were the prime target of explosives expert zealots had a profound effect on Morton's subsequent behavior when arresting Lehi fighters. As a member of the Palestine police he had received pistol training which emphasized
instinctive aiming and the danger of quick-reacting suspects; after the Yael Street bomb those who disregarded a warning to stay still during raids were not given the benefit of the doubt but instantly shot.
Dizengoff Street shooting The authorities offered the large reward of £3000 for information leading to convictions and £1000 for the capture of Stern. One week after the bombing, on 27 January 1942, Morton learned from a Jewish informant that four young men were renting a third floor room at the rear of 30
Dizengoff Street. Morton chose speed and surprise over the delay that cumbersome reinforcements would involve and he raced to the apartment block with only five detectives. On arrival he posted three officers outside and led Wilkin and another
CID man to the room. There were three men inside, relaxing after a day of exchanging information on how to make IEDs - Jacques, Avraham Amper (both leading lieutenants of Stern), and Svorai. The fourth man, Yoske, had gone to the lavatory. The noise of the door opening and a voice making a garbled inquiry about "Mr. Schiff" was taken to be Yoske returning; the three men were caught off guard when Morton threw open the door. By Morton's account, on entering he saw Jacques in front of his wife and two other men lying on beds; Morton shouted in Hebrew "Don't stand up". When the suspects did just that, he opened fire killing Jacques and Amper; Svorai received flesh wounds and Yoske was shot in the buttocks by a detective outside while attempting to escape through the lavatory window. The building is now marked by a plaque commemorating the deaths, and the last headquarters meeting of Stern (in which a plan to assassinate
Oliver Lyttelton was finalized).
Lehi member's account of the shooting According to Svorai, Morton burst in with his pistol leveled and yelled "Hands up!". As the surprised occupants got to their feet and complied, he motioned with his free hand for Wilkin and two other CID men to stay back and shot Amper in the stomach three times, Svorai in the shoulder and leg and Jacques twice in the stomach. ==The death of Avraham Stern==
