Camp pres de Noudam passera Goussan ville,

Et à Maiotes laissera son enseigne,

Conuertira en instant plus de mille,

Cherchant les deux remettre en chaine & legne.

The camp near Houdan will pass Goussainville,

And at Mayotte it will leave its ensign,

In an instant more than a thousand will be converted,

Looking for the two to put them back in chain and firewood.

Houdan is a French commune near to the town of Goussainville.

The Sultan of Mayotte sold the island to France on 25.03.1841 for a life annuity of 1,000 piastres a year. The admiral of the flotilla Piero Passo concluded this treaty with him, which was then ratified by king Louis Philippe on 13.06.1843. The official flag-raising ceremony took place.

The population of this island in the Madagascar archipelago adopted the Christian religion. In 1962 the people of Mayotte demanded to remain a part of France, fearing the return of Muslim power.

The last line could not be decrypted.

Decoding of the number 9.56. If 1 to put in front, 6 to flip in 9 (1959), then 1900-59=1841 is Mayotte's purchase year.
