Yitzhak Rabin: A ship had been sighted opposite El Arish.
      Following standing orders to attack any unidentified
      vessel near the shore (after appropriate attempts had
      been made to ascertain its identity), our air force and
      navy zeroed in on the vessel and damaged it. But they
      still could not tell whose ship it was.... Four of our
      planes flew over it at a low altitude in an attempt to
      identify the ship, but they were unable to make out any
      markings and therefore concluded it must be
      Egyptian....
