There were two confrontations between the newly formed IDF and the Irgun: when "Altalena" reached Kfar Vitkin in the late afternoon of Sunday, June 20 many Irgun militants, including Begin, waited on the shore. A clash with the Alexandroni Brigade, commanded by Dan Even (Epstein), occurred. Fighting ensued and there were a number of casualties on both sides. The clash ended in a ceasefire and the transfer of the weapons on shore to the local IDF commander, and with the ship, now reinforced with local Irgun members, including Begin, sailing to Tel Aviv, where the Irgun had more supporters.
