When Marie Louise left Paris in 1814 her procession included "32 small barrels of gold which Joseph had had fetched up from the basement and which represented Napoleon's personal savings" (from David Stacton, The Bonapartes".
At Chambord, where the entourage stopped, Cossacks attempted to steal the gold but failed, taking a carriage with Marie's hats instead.
On 9 April when Marie and the then remaining parts of her entourage reached Orleans, she was relieved by Msr. Dudon an agent of the Provisonal Govt. of all the diamonds belonging to the crown which were in the caravan, including a pearl necklace she was wearing. No mention of the gold.
