FROM THE BOSTON CENTINEL.

The following particulars of War Preparations in Austria, Russia, France, &c. are collected with same care from various sources; and may be considered as correct as round numbers generally are.

Austrian War Preparations.

The line of troops which Austria is said to have assembled, reaches from the borders of Hungary on the S E. to Switzerland on the W. with a front towards Italy extending nearly to the A-dige; and towards the N. to the circle of Bavaria: with a covering army in Bohemia. This position covers Vienna and the centre of the Empire.

The troops composing this line are said to exceed 200,000 men. (Of which those in Styria, Carinthia, Italy, Venice, Tyrol, near Wels, and Mindendorff, consisting of 271 battalions of infantry and 51 regiments and squadrons of cavalry, besides artillery, sharp-shooters, &c. The French official account declares the Austrian force in Italy alone (including Tyrol) to be 72,000.

These forces will be divided into two grand armies, one to act on the Rhine and Danube, the other in the Italian States.

The army of the Rhine, &c. will be commanded by the emperor Francis II. in person: with the veteran Gen. Mack, for his second in command; and the duke Ferdinand and prince Charles of Schwarzenberg, commanding wings. The emperor left Vienna the 10th Sept. to take the command of his army, which will consist of 130,000 men. The van of this army had advanced into Bavaria.

The army in Italy will be commanded by the celebrated arch-duke Charles: having his brother the arch-duke John, for his second, and prince John of Lichtenstein for his third in command. The veteran gen. Bellegarde is with this army.

One of the armies of Reserve is in Bohemia, and consists of 80,000 men. Hungary was to furnish 50,000 men; and Hesse-Cassel had 36,000 on foot. Two columns of the Austrian army, one commanded by the arch-duke Ferdinand, the other by gen. Klenau, passed the river Inn the 7th and 8th of September; marched towards Danuberg and Munich, to take post on the Lech. These are about 45,000 strong.

The Bavarian forces retreated before these columns towards Wurzburg in Franconia. When collected it is said they will exceed 40,000 men.

Russian War Preparations.

The Russian emperor, in his declaration to the court of Vienna, (published Nov. 22.) has avowed that he had sent two armies into Galicia, of 50,000 men each. These armies, at the last dates, were making forced marches; and it was expected, by the middle of October, would form a junction with the Austrians.

A third army was said to have assembled near Wilna, (formerly Poland) and was to be commanded by Alexander I. in person. The Russian Imperial guards under the Grand duke Constantine (brother of the emperor) were marching through Lithuania for the Austrian states.

The veteran, Gen. Kutusoff, was at the head of one of the armies; prince Peter Bagration, and baron Winzengerode, names of celebrity, accompany these troops. Gen. Michelsen commanded another army.

Troops from the Kuban, Siberia and Kioff will form bodies of reserve. The regular troops of Russia exceed 500,000 men.

One of the Russian armies was at Brod in Gallicia (about 300 miles from Vienna) the 28th August. The other was not far behind.

Thirty thousand Russians embarked at St. Petersburg the 28th Aug. bound to Swedish Pomerania.

The Russian troops in the Ionian islands exceed 80,000, and were daily augmenting by recruits from the Black Sea, which pass the channel of Constantinople without any hindrance. One division lately arrived, was commanded by gen. Gerdene, a Frenchman: and a division of 12,000 was ready for embargation at Odessa and Sebastopol.

It is a fact that no less than 12,000 tons of transport shipping had been provided by Great Britain: and were at the disposal of the Russian commander at Corfu. We have no doubt the next news from that quarter will be the transportation of these troops from the Seven Islands to Ancona, perhaps Venice or Trieste.

French War Preparations.

These preparations are on a large scale and extend from Otranto, at the extremity of Italy to Hanover, on the N. of Germany.

The Grand Army, about the middle of September, was assembled on the banks of the Rhine; composed of 140,000 men commanded by the emperor Napoleon I. in person; assisted by his brother in law, Marshal prince Murat; marshal Berthier, (minister of war) Louis Bonaparte; Generals Oudinot and Marmont. The emperor was at Strasburg the 16th September.

The army in Italy is commanded by marshal Massena, who arrived at Milan, his head quarters, the 7th Aug.--He has with him, of name, marshal Jourdan and gen St. Cyr. This army, though stated at only 50,000 men in Talleyrand's note (already published) was to be augmented to 120,000.

A southern army of observation was to assemble near the Pyrenees, under marshal Augereau.

The grand French army of reserve has 3 head quarters, Boulogne, Mayence and Strasburg: Marshal Brune commands at the first, senator marshal Lefebvre at the second, and senator marshal Kellerman at the third.

Three flying camps of grenadiers will rendezvous at Rennes, Napoleon and Alexandria, under three brigadier generals.

We have collected with care a compendium of the war preparations made and making at our last dates, in Austria, Russia and France. Under the head of each the reader will find the situation, forces, &c. of the armies—We have only to add, that the Austrian advanced troops near the Rhine were at Stochach: That the first division of the French army crossed the Rhine on the 24th Sept. at Mentz, marched towards Weilbach and Stockingen, and were to be at Ossenbach on the 25th of that month. Eighty thousand conscripts were ordered to be raised in France.—Sixty thousand of the Russians were expected to arrive on the Inn the 4th of October.

The files of this new war will be decorated with the following titled warriors—France has sent to the field the emperor Napoleon I. the favorite of victory, attended by prince Louis, his brother, and prince Murat, his brother in law.—Austria sends her twice emperor Francis II. accompanied by his gallant brothers, the arch-dukes Charles and John, and by other branches of the imperial family.—Russia also sends the emperor Alexander I. attended by his brother Constantine. They are all young men; and several of them have been tried in action.

Prussia was in motion—she had a large force ready for the fray:—But was apparently
"Waiting till conquest should decide.
Which was the strongest, safest side."

Sweden had ordered fresh troops into Pomerania, and her monarch had fixed her residence at Christianstadt, to be near the scene of operation.

No blood had been shed at the date of our accounts; but the next late arrivals will bring details of battles lost and won.
