The altalena affair is an interesting part of israeli history. The ship was filled with weapons for the irgun group -a jewish paramilitary group headed by Begin. The Israel defence forces (idf headed by ben gurion) confiscated the ship as its cargo would violate the first 1948 arab-israeli truce and make the irgun more powerfull within the jewish state. 18 men were killed in the struggle. Interesting detail: the inital plaque had a spelling mistake. It said: invaged arab armies. It has been corrected as one can see on this picture
