sentences:  The Lambert Charter Radama had approved conceded significant tracts of land to Lambert in neglect of the island-wide significance attached to ancestral land.In addition, the French government received a letter purportedly written by the prince, requesting French military aid to depose his mother.The origins and authenticity of the letter are disputed, and the British alleged that it was crafted by Jean Laborde (particularly since it was written in French, a language Radama did not know how to write) to support French military action on the island.
