Cameleon's captain was Commander Frederick Lewis Maitland, whom Lallemand would meet again in 1815 in connection with Napoleon's surrender.

During the campaign of the fall af 1813 he served with the Danish troops supporting Napoleon in North Germany, commanding the 30th Light Cavalry Brigade consisting of two squadrons of the 28th French regiment Chasseurs á Cheval and three squadrons 17th (Lithuanian) regiment Lanciers Polonaise.

The next day, April 30, 1817, the Columbian reported: "two more of Bonaparte's late officers have arrived at Boston, from Leghorn--Dufresne Cyprion and Liell Memon."

Lallemand, at Philadelphia, became a president of the French Emigrant Association, an organization that gained a grant of four townships in what is now Alabama for a Vine and Olive Colony.

The planned Texas colony, Champ d'Asile ("Field of Asylum") was meant for defeated Napoleonic veterans.

Lallemand and his brother reached New Orleans, Louisiana on February 2, 1818, gathered new recruits and on March 10 left for Galveston with 120 volunteers.

However, the Mexican governor Antonio Maria Martinez heard about the French, prepared an expedition to the Trinity River and stationed a force at San Marcos to guard against possible attacks.

Jean Lafitte and Amable Humbert helped some of the survivors to return to Louisiana and the rest walked back to New Orleans in August 1818.
