1637 naval expedition against Salé

On the orders of Charles I of England, Rainsborowe led a successful naval expedition against the Barbary corsairs of Salé in North West Morocco in June 1637. The squadron comprised four of the warships of Charles I, together with two privately owned ships - the Hercules and the Mary. Two additional English warships were later sent out as reinforcements - the Mary Rose under Capt. Thomas Trenchfield, and the Roebuck under "Master Broad of Rotherhithe". Rainsborowe's exploits were hailed in a court masque designed by Inigo Jones For his services to end white slavery Rainsborowe was offered a hereditary knighthood, which he declined, and was presented with a Gold Chain and Medal by Charles I.
Captain Rainsborowe's Emblem was a Saracen's head crest. The Saracen Head as interpreted as 'the head of the foreigner'; the foreigner being the much-feared pirates of the north African coast. Usually referred to as Turks, these marauders were in the white slavery business. This emblem represented Captain Rainsborowe's success at ending White Slavery against the Barbary pirates in Morocco in 1637.
