By the morning of 15 July, the outcome appeared clear to the king as well, and he and his military commanders backed down. The Royal troops concentrated around Paris dispersed to their frontier garrisons. The Marquis de la Fayette took up command of the National Guard at Paris; Jean-Sylvain Bailly – leader of the Third Estate and instigator of the Tennis Court Oath – became the city's mayor under a new governmental structure known as the Commune de Paris. The king announced that he would recall Necker and return from Versailles to Paris; on 17 July, in Paris, he accepted a tricolour cockade from Bailly and entered the Hôtel de Ville to cries of "Long live the King" and "Long live the Nation".
