While the republican government was amenable to war reparations or ceding colonial territories in Africa or in South East Asia to Prussia, Favre on behalf of the Government of National Defense, declared on 6 September that France would not "yield an inch of its territory nor a stone of its fortresses." The republic then renewed the declaration of war, called for recruits in all parts of the country and pledged to drive the German troops out of France by a guerre à outrance. Under these circumstances, the Germans had to continue the war, yet could not pin down any proper military opposition in their vicinity. As the bulk of the remaining French armies were digging-in near Paris, the German leaders decided to put pressure upon the enemy by attacking Paris. By September 15, German troops reached the outskirts of the fortified city. On September 19, the Germans surrounded it and erected a blockade, as already established at Metz.
