Franco-Thai War: Final air battle of the conflict. A Japanese-mediated armistice goes into effect later in the day.

The Franco-Thai War was fought between Thailand and Vichy France over certain areas of French Indochina.

An armistice is a formal agreement of warring parties to stop fighting. It is not necessarily the end of a war, as it may constitute only a cessation of hostilities while an attempt is made to negotiate a lasting peace. It is derived from the Latin arma, meaning "arms" and -stitium, meaning "a stopping".
