Sturgeon was specially mentioned in Wellington's despatch, both for his services during the siege and for his construction of a bridge over the Águeda, which was an indispensable preliminary to it.

[1] Sturgeon was again specially mentioned in the Salamanca despatch, and was sent three months afterwards to make a bridge at Almaraz.

In February 1814 he took a prominent part in the bridging of the Adour, and was one of the officers praised by General Hope in his report for the zeal they showed in the execution of that project.

[1] A few weeks afterwards, on 19 March, Sturgeon was killed by a bullet as he was riding through a vineyard during an action near Vic-en-Bigorre.

Napier described him as "Skilled to excellence in almost every branch of war, and possessing a variety of accomplishments, he used his gifts so gently for himself and so usefully for the service that envy offered no bar to admiration, and the whole army felt painfully mortified that his merits were passed unnoticed in the public despatches".
