 One hour before the truce , the High Command decided to try a frontal assault against the police fort . Intelligence indicated that , in effect , it was " more likely than not " that the Legion 's forces in the sector were " substantial " . In the morning , reconnaissance patrols had sized up the sector , but could not confirm or deny the information that had been gathered by the intelligence . At 6 pm two Cromwell tanks driven by British deserters , seconded by a mechanised battalion of the Yiftach and supported by artillery launched the attack of the police fort .
