 The Irgun publicly threatened a violent reaction if on September 27, the Yom Kippur holiday, the police attempted to stop the blowing of the shofar.The Irgun in fact had no intention of shooting in the midst of a large Jewish crowd at the Western Wall, but planned a series of attacks on four police Tegart fortresses.If the British would withdraw in the face of the Irgun threat, the attacks would seem unconnected to the threats of violence at the Western Wall, and if they defied the Irgun and attempted to stop the blowing of the shofar, the attacks on the fortresses would be the Irgun's response.
