This refers to Louis Bonaparte’s attempts during the July monarchy to stage a coup d’état by means of a military mutiny. On October 30, 1836 he succeeded, with the help of several Bonapartist officers, in inciting two artillery regiments of the Strasbourg garrison to mutiny, but they were disarmed within a few hours. Louis Bonaparte was arrested and deported to America. On August 6, 1840, taking advantage of a partial revival of Bonapartist sentiments in France, he landed in Boulogne with a handful of conspirators and attempted to raise a mutiny among the troops of the local garrison. This attempt likewise proved a failure. He was sentenced to life imprisonment, but escaped to England in 1846.
