    A map of the British attacks on Forts St Louis, St Jago and St Philip at Cartagena in 1741. War with Spain (Jenkins's Ear) (1739-48): part of the War of the Austrian Succession (1740-48). Oriented with east to top (compass rose).

    The combined operations attack, under the command of Admiral Vernon and Brigadier General Thomas Wentworth (d.1747), on Spanish-held Cartagena was intended to achieve British control over trade in the West Indies. The action took place between the middle of March 1741 and ended in a British defeat by June.

    The grounds for the attribution, in the old catalogue, to ‘Captain Thomas Eng.r’ are not known. According to Conolly (List 2, no.75, p.4), a Practitioner Engineer by the name of John Thomas saw service in Cartagena and died in Flanders in 1747. No other rank is given for him, although he may have held a captain's rank in the army. If this John Thomas is not the author of this map, then it is possible that the Captain referred to in the old catalogue was a Captain of a Regiment of Foot who was temporarily appointed as an engineer. The map appears to be unfinished: the letters which are explained in the References do not appear on the map. Another, finished manuscript copy of this map by John Thomas, dedicated to the Duke of Montagu, is in the Library of Congress, Call Number G5294.C3S5 1741 .T5 Vault.
