[120] General Packenham was killed and the British suffered over 2,000 casualties; the Americans had suffered about 60 casualties.[121]
The British decamped from New Orleans at the end of January, but they still remained a threat.[122] Jackson refused to lift martial law and kept the militia under arms. He approved the execution of six militiamen for desertion.[123] Some Creoles registered as French citizens with the French consul and demanded to be discharged from the militia due to their foreign nationality. Jackson then ordered all French citizens to leave the city within three days,[124] and had a member of the Louisiana legislature, Louis Louaillier, arrested when he wrote a newspaper article criticizing Jackson's continuation of martial law. U.S. District Court Judge Dominic A. Hall signed a writ of habeas corpus for Louailler's release. Jackson had Hall arrested too. A military court ordered Louiallier's release, but Jackson kept him in prison and evicted Hall from the city.[125] Although Jackson lifted martial law when he received official word that the Treaty of Ghent, which ended the war with the British, had been signed,[126] his previous behavior tainted his reputation in New Orleans.
