Extract of a letter from Cadiz, dated June 27.

"We are in hourly expectation of hearing of the surrender of General DuPont and his army consisting of nearly 9000 men, within three leagues of Cordova, and 250 miles from Cadiz. This is a division of French troops that were on their march to Seville when the revolution commenced, detached by the duke of Berg from the Grand Army, consisting of about 70,000 men, in the vicinity of Madrid. There are now only 3000 men in the vicinity of the metropolis; the residue of this large army were detached to take possession of different parts of the country, and were marching with the utmost confidence when the revolution commenced. DuPont must inevitably surrender, as he is hemmed in on all sides by an army much superior to his own, and without hope of relief. The French army that originally arrived in this country consisted of about 90,000 men, and were in possession of many principal towns. From the immense territory over which they are scattered, without being able to form a junction in season and make good their retreat, and from the energy with which the Spaniards have acted, there is no doubt but the major part of this immense army will eventually fall into the hands of the Spaniards."
