Primary Documents - Triple Entente 'No Separate Peace' Agreement, 4 September 1914

Theophile Delcasse With the war underway there was concern among the Entente Powers that none among them should attempt to negotiate a separate peace with the Central Powers, thus gravely weakening the ability of the remaining belligerents to continue the war.

Thus the 'No Separate Peace' agreement came about, agreed by Britain, France and Russia in Paris on 4 September 1914, barely a month into the war.
