At length we have really decisive news from Portugal. Don
MIGUEL, after the surrender of Santarem, attempted to retreat to Elvas, with a small army, weakened by disease, and constantly becoming thinner by desertion. He was pressed by SALDANHA on one side, and TERCEIRA on the other. In this extremity, he of- fered an armistice to SALDANH A, who suspended operations and sent to Lisbon for instructions. The Government reprimanded the General for allowing the Usurper an hour's delay, and refused the armistice. Don MIGUEL then made the best bargain in his power for himself; and was permitted to go on board a British man-of-war, which will probably soon convey him to our shores. He will doubtless be received with open arms by those congenial spirits Lords LONDONDERRY and ABERDEEN; unless, indeed, the recollection of the abusive terms which the latter once profusely showered upon his head should produce a temporary coolness be- tween them. It is said that Don MIGUEL has secured an allow- ance of about 12,000/. a year for his future support.
The Government of Donna MARIA has proclaimed an amnesty for all political offenders, provided they surrender themselves, and return to their allegiance within a certain time. Sir JOHN CAMPBELL has been permitted to leave his prison on parole. It is not known where Doti CARLOS has lied to; but there is a re- port that he has made an irruption into Spain at the head of some troops, in company with a son of BOURMONT.
