Annales historiques de la Révolution française - Année 1985 - Volume 261 - Numéro 1 - Pages 317-334Our aim in this article was to try to find evidence of the traditional belief that the two precious offered to Louis XIV by the King of Siam and brought by his official envoys in 1686, were fired on the Bastille on July 14, 1789 (an anecdote not lacking in irony...); Our research led us to discover that these cannons were in the Royal Furniture Repository where they were stolen on July 13, 1789, and transported the next day to the gates of the fortress against which they were in fact used. Their fate thereafter is uncertain. One was recovered by the Repository, but stolen again in 1792 for the benefit of one of the gunners' batallions of the capital. It is probable that both of them continued to be used until they no doubt deteriorated or were rendered unrecognizable by the theft, however absurd, of their silver damascene inlay. M.
