In three days after his departure, king Philip abandoned the siege and retired in great disorder, leaving behind his tents, with the sick and wounded.
On the side of Portugal, the duke of Berwick was left with such an inconsiderable force as proved insufficient to defend the frontiers.

The earl of Galway, with an army of twenty thousand men, undertook the siege of Alcantra; and in three days the garrison, consisting of four thousand men, were made prisoners of war.

Then he marched to Placentia, and advanced as far as the bridge of Almaris; but the Portuguese would penetrate no farther until they should know the fate of Barcelona.
When they understood the siege was raised, they consented to proceed to Madrid.

Philip guessed their intention, posted to that capital, and sent his queen with all his valuable effects to Burgos, whither he followed her in person, after having destroyed everything that he could not carry away.

About the latter end of June, the earl of Galway entered the city without resistance; but the Spaniards were extremely mortified to see an army of Portuguese, headed by an heretic, in possession of their capital.
