LATEST FROM PORTUGAL.

By the brig Wanderer, Captain Sutton, arrived at this port yesterday in 34 days from Lisbon, from whence she sailed on the 15th, of Aug. we have received the following verbal intelligence.

Accounts were received from Lord Wellington as late as the 12th August, three days before the Wanderer sailed—his headquarters were at Celerico, but the advanced guard of the army was at Guarda; he was momentarily expecting an attack from the French, who had advanced as far as Penhel, in Portugal several skirmishes had taken place between the advanced parties of both armies—one on the 24th July was very severe, the British having lost 16 officers—The troops that were in Alentejo, under General Slade, have crossed the Tagus and joined Lord Wellington, It is supposed his Lordship has 35,000 effective men, besides about 17,000 Portuguese, exclusive of the Portuguese army under Marshal Beresford. The 7th regiment had arrived in fine order, from Halifax, and the 23d (fusiliers) were daily expected, from the same place: the former, after remaining 3 or 4 days at Lisbon, were marched off to the army.

They are very active in Lisbon procuring recruits, and numbers are sent off daily to head quarters.—Every horse that was able to stand was immediately impressed for the cavalry.

There were 8 or 10 line of battle ships, besides frigates and small vessels of war lying in the Tagus, and nearly 700 transports waiting to carry off the British troops, in case they were obliged to leave Portugal. —Strong fortifications have been erected on the heights about Lisbon to cover their retreat in case of need.—Upwards of 15,000 barrels of flour was expected at Lisbon from Liverpool for the use of the army, it is principally American flour, purchased at Liverpool by government: the bills of lading for the same had arrived before the Wanderer sailed.

By arrivals at Boston, and at Newburyport, Lisbon papers to the 6th August have been received. The latest accounts from the Anglo Lusitanian Army are to the 2d August, when its head-quarters were at Celerico, but it was contemplated to advance them to Alverca. The Portuguese troops, under Marshal Beresford, had joined those of Lord Wellington at Celerico.

The French had been before Pinnel, (6 or 8 miles N. W. of Almeida) but had recrossed the Coa. There appears to have been no fighting from the 24th of July to the 2d of August.

On the 23d of July, 8 or 9000 French troops, with 8 pieces of artillery passed the Douro, not far from Zamora, and threaten the northern province of Portugal. We perceive no farther mention of Regnier's Division, which passed the Tagus at Almarez, apparently with a view of joining Massena. He was closely pressed by a corps of Patriot troops, & it is said had 400 of his rearguard cut off. The British division under General Hill, watched that of Regnier. As soon as the latter began to withdraw from Estremadura, the Spaniards recovered fresh spirits, and many military movements are mentioned. Patriot detachments are noted as having marched from Albuquerque to Caceres, Truxillo, and Almarez. Foreseeing this effect, it is said, the French division of 8000 men, under Mortier, which has been for some time at Seville, had began its march for Estremadura. The papers, as usual, contain many accounts of small rencounters in Spain, in which the French were defeated; and they relate many instances of desertion—among others, that of an entire regiment of Polish Cavalry. Portugal has made peace with Algiers, through the mediation of England. A new contribution, for the support of the nation against the French, is making throughout Portugal. Fifteen-thousand troops, from Cadiz, had been landed at Ayamonte.
