These successes in the palace were followed by equal successes in the city of Lisbon. The populace of all classes detested the Spanish domination; they rose in a body, armed themselves as best they could, and arrested every Spaniard they could find from the Marquis de la Puebla to the naval officers on shore from the Spanish vessels lying in the Tagus. Dom Antonio de Saldanha, as previously arranged, entered the _Relacão_, or High Court of Justice, and informed the judges of the revolution, and the president, Gonçalo de Sousa, immediately began to pronounce his decrees in the name of King John IV., instead of King Philip III. Dom Gaston de Coutinho set free all the political prisoners, and some young men rowed off to the three Spanish galleons in the port, and easily obtained possession of them, since most of their officers had already been arrested on shore. There remained only the citadel, or castle, of St. George, garrisoned by a strong Spanish force under Don Luiz de Campo. This important post was obtained by a stratagem of Dom Antonio de Almada, who forced the Duchess of Mantua to sign an order for its surrender by a threat to assassinate all the Spanish prisoners already taken, and the order was willingly obeyed by the timorous governor. The conspirators then assembled in the palace, and amidst the shouts of the populace, the Archbishop of Lisbon was proclaimed Lieutenant-General of the kingdom, with Dom Miguel de Almeida, Dom Pedro de Mendonça Furtado, and Dom Antonio de Almada as councillors of state. The new government sent off expresses in all directions to announce the news of the successful revolution, and obtained peaceable possession of all the chief fortresses and strong places round Lisbon, of Belem, Bugio, S. Antonio, Almada, and Cascaes, with the exception only of S. Julian, at the mouth of the Tagus.
