By Telegraph. The Situation at Men and Paris. Paris, Aug. t-. The Journal Official Offi-cial contains .he fol. owing dispatch : Metz, August 7th, 9:U0 a.m. In the battle of Saturday, near Keichoffen, McMahon's chief of staff, General Col-son, Col-son, was shot by the Marshal's side. General Koult is among the missing. Our artillery suffered heavily. Mc-Mahon Mc-Mahon is in communication with Gen. Failly. Metz is preparing for a vigorous vigor-ous defense. The genera commanding the fortress has ordered the Germans and strangers to provide themselves with permissions of residence. An imperial decree has appeared convoking the Senate and Corps Leg-islatif Leg-islatif to-morrow. The report of the minister of war, approved by the Empress, Em-press, is published in the Journal. The minister says : Existing circumstances circum-stances oblige us to provide for the defense de-fense of the capital and to garrison it with French troops, allowing all those which the Emperor keeps under his orders to contend in the open country against an euemy emboldened by his first success to the point of marching on Paris. But Paris will not be taken unawares. The exterior forts have received re-ceived their arms some time ago, and we have commenced to arm around the city. A state cf siege has been declared de-clared and the execufion of the works will be commenced to-morrow. Thus I the exterior forts are in a condition to sustain a siege, and in a few days the entire circuit of the walls will be found in a similar condition. Neither the strong arms nor the devotion of the inhabitants will be wanting for this task. The national guard is to defend the ramparts, which it will have helped to render unassailable. Forty thousand thou-sand men, taken from its ranks and added to the present garrison, will be more than enough to- make an active defense against an enemy occupying an extended front, lhe defense of Paris, therefore, will be assured ; but there is a point not less essential. It is the necessity of tilling up the void in our army. With the regiments still at our disposal in France and Algeria, and with the fourth battalion of each of our hundred regiments, including those members who belong to the garde mobile, and with a portion of our gens d'armes.we may easily put into in-to the field 150 000. Besides this, the class of 1 S09 will give us 00,000 men, who in a month will become real sol diers. , We can also employ the entire national na-tional and mobile gardes, and the companies com-panies of France, who are everywhere asking to be organized. Here we have 400,001' men; and finally, counting on the garde nationale snli ntaire, France can arm two millions of defenders. Their arms are ready and a million are still in reserve. A decree is issued ordering the narde nationale of Paris to be detailed fur the uj'.I :ice of the capital, and that the forts be placed in a condition to resist attack. A project of law will be presented to tho chambers for the incorporation in the national and mob le gardes citizens under thirty years of age who are not actually members.
