The mission members included French diplomat, Jean Jules Jusserand, general Maxime Weygand, chief of staff to Marshal Ferdinand Foch (the Supreme Commander of the victorious Entente), and the British diplomat, Lord Edgar Vincent D'Abernon. The crucial battle of Warsaw was won in the early days of August, before the mission could achieve anything of importance. The only tangible result was the installation of Weygand as an advisor the Polish General Staff, where his role was negligible. Nevertheless, soon after the battle and for various political reasons, a myth arose that Weygand was the author of the Polish victory in the battle of Warsaw.
