Events moved rapidly. The Emperor sent orders on 19 July 1807 to his Foreign Minister, Charles Maurice de Talleyrand-Périgord, to order Portugal to declare war on Britain, close its ports to British ships, detain British subjects on a provisional basis and sequester their goods. After a few days, a large force started concentrating at Bayonne. Meanwhile, the Portuguese government's resolve was stiffening, and shortly afterward Napoleon was once again told that Portugal would not go beyond its original agreements. Napoleon now had all the pretext that he needed, while his force, the First Corps of Observation of the Gironde with divisional general Jean-Andoche Junot in command, was prepared to march on Lisbon. After he received the Portuguese answer, he ordered Junot's corps to cross the frontier into the Spanish Empire.
