“must see some steps taken to re-establish a government in France which should afford the Allies some chance of peace” before he could sanction a suspension of hostilities; that he personally “conceived the best security for Europe was the restoration of the King, and that the establishment of any other government than the King’s in France must inevitably lead to new and endless wars;” and he concluded by these words: “That, in my opinion, Europe had no hope of peace if any person excepting the King were called to the throne of France; that any person so called must be considered an usurper, whatever his rank and quality; that he must act as an usurper, and must endeavour to turn the attention of the country from the defects of his title towards war and foreign conquests; that the Powers of Europe must, in such a case, guard themselves against this evil; and that I could only assure them” (the Commissioners) “that, unless otherwise ordered by my Government, I would exert any influence I might possess over the Allied Sovereigns to induce them to insist upon securities for the preservation of peace, besides the treaty itself, if such an arrangement as they had stated were adopted”—viz., any arrangement whereby a prince, other than the King, were called to the throne of France.[18] ----- Footnote 18: Siborne, ii. 427, etc. ----- On the 29th, Blücher pressed on towards Paris, and reconnoitred the defences thrown round the northern side of the city. The remnants of the great army which had been shattered at Waterloo also entered the capital on that day, and the French mustered some 80,000 to 90,000 men there—troops from the provincial depôts and from the country having been called for the defence of the seat of government, and as many discharged veterans as could be collected having been assembled in a special corps some 17,000 strong. Besides this, there was plenty of artillery available, and about 30,000 of the Garde Nationale; but on the latter no great reliance could be placed. Marshal Davoût, Prince d'Eckmühl, was appointed Commander-in-chief. The British forces were still in rear, and occupied positions between Gournay and St. Maxence, the Guards Division being near St. Martin Longeau. At dawn, on the 30th of June, the advanced French post at Aubervilliers was attacked by the 4th Prussian Corps under Bülow, and the enemy was driven back, and pursued as far as the canal in rear of that village; but it became evident that to dislodge him from that line, a more serious effort would be necessary.
