LONDON, Aug. 15.

The arrivals from the Russian army are frequent, and happily enable us to detect the falsehoods of the French Bulletins almost as soon as we receive them. We are now in possession of Russian accounts to the date of the last French Bulletin. They confirm one piece of intelligence which we shall mention before we proceed to the operations that preceded it. Prince Bagration has effected his junction with the main army. His whole march from the frontiers of the Palatinate of Trecki to the Dwina was a series of actions and successes. Romanow and Mohilow will long be remembered by the enemy. At the first place, on the 10th of July, gen. Platow, who covered the march of Bagration with his Cossacks, was attacked by seven regiments of French cavalry, which he defeated and pursued to a great distance. Two of the regiments were totally destroyed. At Mohilow, Bagration was attacked by the whole of Davoust's cavalry and a large body of infantry. An obstinate battle ensued, which terminated in the complete defeat of the enemy, who left between 5 and 6000 on the field and took prisoners, including between 50 and 60 staff officers. The French artillery was also taken. The enemy seem to have been heartily tired of making any further attempts to impede Bagration's march, which from Mohilow to the Dwina, appears to have been executed without difficulty. This success of Bagration, who it must be confessed seemed to be in the greatest danger from his long distance from the main army, and from the manner in which Bonaparte spread himself from the Wilta to the Berezvna, has caused universal exultation. At Riga and other places Te Deum was sung, and there were rejoicings and illuminations.

The Russian bulletins confirm also the repulse of the enemy in their attack upon the tete-de-pont of Dunaburg on the 13th and 15th ult. It will be recollected that the 8th French bulletin, speaking of this first attack, said that, "on the 8th Oudinot advanced upon Dunaburg, burnt the fine barracks, took a plan of the works, burnt some magazines, took 150 prisoners, and after this diversion marched on Druia" (which is on the left of the Dwina.) We inferred, from these expressions, that Oudinot had really been driven back by the Russians, and forced to fly to Druia to strengthen himself by Sebastiani's corps—and the Russian bulletin proves that our inference was correct. Of the attack on the 15th the French bulletin said nothing, but passed on rapidly to the attack on Sebastiani on the 15th. This attack was said to have been made with 10,000 men. The Russian bulletin states that it was made by a regiment of hussars and a few squadrons of Cossacks—and that two regiments of French cavalry were completely cut up.

The emperor Alexander in a manly proclamation, calls upon his subjects to defend the country with all their vigour and all their resources, and the country appears to answer the call with the greatest alacrity. The nobility of Smolensko have offered to raise 20,000 men at their own expense. Moscow and other places are following this patriotic example, and a fresh levy of one man in every hundred has been ordered to be raised within a month. Half a million of men will be added to the Russian armies.

Bonaparte is said to have issued a proclamation announcing his intention of marching direct to Moscow. To this proclamation the Russians have replied by saying, that he will have to cut his way thro' a brave and determined Russian army, zealous in the cause of their country, and determined to defend it to the last extremity. At Vitepsk they were concentrated, and there a battle has probably been fought.

The two last French bulletins left us in the dark with respect to the movements of Macdonald, who appeared to be marching in the direction of Mitau and Riga. If we may give credit to some private letters, he has been defeated at the head of 15000 Prussians in the vicinity of Mitau.

The ratification of the treaty of peace with the Porte releases the whole of the Russian army that was in Turkey and it will also be recollected, that in pursuance of that treaty, the Porte engages to furnish 50,000 men against Austria, if she should attack Russia.

Russian Head Quarters. July 22.
Bonaparte has issued a proclamation announcing his intention of marching direct to Moscow, but the Russian army is fully prepared to stop his progress whenever they think proper.

Smolensko. July 21.
His Majesty arrived here yesterday, and intends to proceed to Moscow.
Te Deum has been sung at Moscow in consequence of the ratification by the Grand Signior of the peace concluded between the Porte and Russia.

"A FAIR" OF ROMANOW.
St. Petersburgh. July 26.
Gen. Platow, whose corps forms the rear guard of Prince Bagration's army has attacked near Romanow by seven French regiments of cavalry, which he broke entirely, and pursued them 15 wersts. The first regiment of those Yagers, one of the best in the whole French army, and also regiment of horse grenadiers, were totally destroyed in this "affair. Two colonels, 15 officers, and 300 men were made prisoners.

EUROPEAN AFFAIRS.
We continue to receive very important and official advices from Europe. The war in Russia was advancing rapidly to a crisis, and there had been some sharp fighting between the Russians and French, in which both sides claim the advantage. We insert the 7th, 8th and 9th French bulletins and some Russian official statements this day: which will give the reader a view of the posture of affairs at the late dates. Bonaparte was bending on Moscow, the ancient capital of Russia; and the Russians were concentrating an army to give him battle on the way. Some comments on the progress of war will be found under the foreign head. The reported "stray" Seventh bulletin has been found, as Paddy would say, before it was lost; and the careful reader will see by its contents
