Help!' he shrieked shrilly in a voice strangling in its own emotion, as the policemen carried him to the open doors in the rear of the ambulance and threw him inside. 'Police! Help! Police!' The doors were shut and bolted, and the ambulance raced away. There was a humorless irony in the ludicrous panic of the man screaming for help to the police while policemen were all around him. Yossarian smiled wryly at the futile and ridiculous cry for aid, then saw with a start that the words were ambiguous, realized with alarm that they were not perhaps, intended as a call for police but as a heroic warning from the grave by a doomed friend to everyone who was not a policeman with a club and gun and a mob of other policemen with clubs and guns to back him up. 'Help! Police!' the man had cried, and he could have been shouting of danger.
