He was in the retreat from Corunna, and immediately after accompanied the expedition to Walcheren, where he was commended for his abilities and zeal during the disastrous prevalence of intermittent fever and other camp sickness.
After the peace he was appointed to take charge of the large hospital erected at Colchester for the sick and wounded from the field of Waterloo.
In 1829 he was appointed principal medical officer in Ceylon, from which he returned in 1836 with his health broken by the climate.
He was promoted to the rank of inspector-general of hospitals, and nominated to the chief direction of the army medical department in India, but was unable from ill-health to proceed to his post.
He died at Maddox Street in London on 7 November 1837, aged 59, and was buried in Rochester Cathedral.
