According to his entry in the British Naval Biographical Dictionary, 1849, Matthew Young
“On 20 Oct. 1807, while in charge of a prize Indiaman, … was captured by the enemy and taken to France, where he was detained a prisoner until May, 1814.”
This intriguing little nugget throws up some interesting questions.

His son, Alfred Young, was apparently born in 1811 in Verdun, France.
