Answer:
The French joining the side of the patriots to the official end of the war is explained below in details.
Step-by-step explanation:
In 1774 followers of the Patriot faith reached French administrators requesting assistance, but the French Foreign Minister, the Comte de Vergennes, ruled it was too early to get involved.
There were a couple of important requirements for France to fully support the American revolutionaries: first, they had to disclose their freedom, and second, they had to prove that they were competent in protecting themselves against the British troops. Until these requirements were met, Vergennes chose to formally remain neutral, but early in 1776, he started quietly sending military equipment and financial support to the Americans.
