I think the inscriptions on the medal say enough, but here's a Wikipedia link that tells the story and also explains the celebration which the medal celebrates. Enjoy.
The medal celebrated America's strong alliance with France and the French military might during the Revolutionary War. France was not so much concerned about the survival of the United States as it was with the influence and expansion of the British Empire.
