Bertrand Count Henri Gratien
Bertrand, Count Henri Gratien, was born in 1773, and served under Napoleon in Egypt, at Austerlitz, Friedland, Wagram and Moscow, becoming ultimately Grand Marshal of the Household. He bravely covered the retreat of the French from Leipzic, and contested the advance of the Allies to Paris. He then shared the emperor's exile both at Elba and St. Helena. On his return to France in 1821 he was restored to his rank and honours, and sat as a deputy for many years. In 1840 he went to St. Helena with the Prince de Joinville to bring over Napoleon's remains. He died in 1844.
