 The great controversy that surrounded the knights' "corso" was their insistence on their policy of 'vista'.This enabled the Order to stop and board all shipping suspected of carrying Turkish goods and confiscate the cargo to be re-sold at Valletta, along with the ship's crew, who were by far the most valuable commodity on the ship.Naturally many nations claimed to be victims of the knights' over-eagerness to stop and confiscate any goods remotely connected to the Turks.
