Moncharmin and Richard were actually the sons of a French military officer named François de La Garde. The two brothers were born in the 1640s and they spent their childhood in France. However, in the 1660s, they were forced to flee the country after becoming involved in a scandal.
The two brothers traveled to England, where they claimed to be the rightful heirs to the French throne. They claimed that their father, François de La Garde, was the illegitimate son of Louis XIV. Moncharmin and Richard were able to gain the support of several English noblemen, who believed that they could use the brothers to restore the Catholic faith to England.
In 1688, Moncharmin and Richard invaded France with a small army of English soldiers. However, their invasion was unsuccessful and they were forced to flee the country again. They then traveled to Portugal, where they continued to plot against Louis XIV.
In 1696, Moncharmin and Richard were arrested by the Portuguese authorities and extradited to France. They were both put on trial and found guilty of treason. Moncharmin and Richard were executed in Paris on 23 December 1696.
The story of Moncharmin and Richard is a fascinating tale of intrigue, betrayal, and ambition. The two brothers were willing to risk everything in their quest to overthrow the French monarchy. However, their plans ultimately failed and they paid the ultimate price for their actions.
