The outbreak of the War of the Austrian Succession led to an expansion in the size of the British Army. In April 1745, Burgoyne joined the newly raised 1st Royal Dragoons as a cornet, a commission he did not have to pay for as it was newly created. In April 1745, he was promoted to lieutenant. In 1747, Burgoyne managed to scrape the money together to purchase a captaincy. The end of the war in 1748 cut off any prospect of further active service.
