Sturgeon was again specially mentioned in the Salamanca despatch, and was sent three months afterwards to make a bridge at Almaraz. In April 1813 he was placed in charge of the corps of guides, and the post-office and communications of the army. 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. C. J. Napier, who speaks of it as a "stupendous undertaking, which must always rank among the prodigies of war" in his "War in the Peninsula", attributes its conception to Sturgeon.
