Albert Jean Michel de Rocca was born in Geneva in 1788, but joined the French Army. Whilst serving in the Iberian Peninsula he was seriously wounded. Back in Geneva, he had an affair with Germaine de St Stal who famously opposed Napoleon and was exiled. Eventually the couple married and after Waterloo they settled in Paris. As well as his Peninsular War memoirs, de Rocca also wrote about the failed British attempt on Walcheren in 1809, entitled La campagne de Walcheren et d'Anvers.
