"the sailing of the Armada against England, after whose defeat the English had a commemorative medallion struck"

   The late-16th century conflict between Catholic Spain and Protestant England came to a head in 1588 when Philip II of Spain launched a full-scale naval invasion of Britain.  After being temporarily repelled by English forces, the Spaniards retreated around the west coast of Ireland, where a combination of the current and unusually powerful gales destroyed what remained of their fleet's invasive prospects.  This event was seen by many in England as a sign of the nation's divine righteousness, and was commemorated in a number of medals bearing inscriptions such as flavit et dissipati sunt ('He blew with His winds, and they were scattered').
