If Portugal failed to accomplish the five conditions of this ultimatum, it would be invaded by Spain, supported by 15,000 French soldiers. The British could not promise any effective relief, even as Prince John appealed to Hookham Frere, who arrived in November 1800. In February, the terms were delivered to the Prince-Regent; although he sent a negotiator to Madrid, war was declared. At the time, Portugal had a poorly trained army, with less than 8,000 cavalry and 46,000 infantry troops. Its military commander, João Carlos de Bragança e Ligne (2nd Duke of Lafões), had barely raised 2,000 horse and 16,000 troops. and was compelled to contract the services of a Prussian colonel, Count Karl Alexander von der Goltz, to assume command as field marshal. The Spanish Prime Minister and Commander-in-Chief, Manuel de Godoy, had some 30,000 troops at his disposal, while the French troops under General Charles Leclerc (Napoleon's brother-in-law) arrived in Spain too late to assist Godoy, as it was a short military campaign.
