The Moniteur publishes two decrees of the President of the Republic. By the first, considering that the existing condition of Paris renders necessary the union in one hand of all the disposable forces of the national guard and of the army, it is decreed, that General Changarnier shall unite the superior command of the national guard of the Seine with the command of the troops of the first military division, until the public tranquillity shall be restored in the capital. By the second, the city of Lyons and all the circuit comprised in the sixth military division are placed in the state of siege. Arrests continue to-day. The whole number is three hundred.... Letters and papers seized will lead to other arrests. By a decree of the Executive the following newspapers are suppressed, (naming six.) ------------------------------------------------------------------------ THE BATTLE OF JUNE 30TH. GENERAL GARIBALDI'S LAST OFFICIAL REPORT IN ROME. _General Head-quarters, San Pietro in Montorio, July 1, 1849._—Yesterday was a day fruitful in deeds of arms: losses and advantages. Yesterday Italy counted new martyrs. Colonel Manara leaves a void in the Republican files, difficult to be supplied. Young, of surprising merit and valor, he was struck by an enemy's ball, while courageously defending the Villa Spada against an enemy very superior. America yesterday gave, with the blood of a valiant son, Andrea Aghiar, a pledge of the love of liberal men of all countries for our fair and unfortunate Italy. Lieutenant Colonel Medici distinguished himself by skill and courage, in the defence of the first bastion on the right of the gate of San Pancrazio, and of the position Savorelli. He was distinguished in the company of the brave Colonel Ghilardi, commandant of that line. The Medici Legion and the first of the line fought like lions. They several times repelled assaults in the breach, and paid with the precious life of many young men, the hope of the country, the sacred debt of all. Part of the Manara Legion fought at the point of the bayonet with their accustomed courage, in union with the companies of the regiment Massi. The Italian Legion, under the command of Colonel Manara, showed itself worthy of its fame in the defence of the Villa Spada. The Third of the Line, in defending the positions which were confided to it, covered itself with glory. GARIBALDI. ------- THE CITY TO CEASE HER RESISTANCE.
