The ultimatum was made, according to Even, "in order not to give the Irgun commander time for lengthy considerations and to gain the advantage of surprise." Begin refused to respond to the ultimatum, and all attempts at mediation failed. Begin's failure to respond was a blow to Even's prestige, and a clash was now inevitable. Fighting ensued and there were a number of casualties. In order to prevent further bloodshed, the Kfar Vitkin settlers initiated negotiations between Yaakov Meridor (Begin's deputy) and Dan Even, which ended in a general ceasefire and the transfer of the weapons on shore to the local IDF commander.
