British medal struck to commemorate the anticipated victory over Cartagena de Indias by Admiral Vernon. The medal erroneously anticipated the surrender of Blas de Lezo while defending Cartagena de Indias, when in fact it was one of the worst defeats suffered by the English Navy.
On the obverse is a full-length image of Admiral Vernon. He is being handed a sword by a kneeling Blas de Lezo, symbolising the surrender of the Spanish. Above Lezo's head is the inscription ''DON BLASS." Sir Chaloner Ogle observes the scene. The inscription says ''THE. PRIDE . OF . SPAIN . HUMBLED . BY . AD . VERNON.''
On the back, the city of Cartagena is depicted with its port closed off by a chain as several ships approach. Inside the port is a vessel and, above it, the inscription ''DON BLASS and THEY . TOOK . CARTAGHENA . APRIL. 1741.''
