The position of the government was growing increasingly desperate. Rumors of a liberal coup to oust Maria Cristina abounded in Madrid, compounding the danger of the Carlist army which was now within striking distance of the capital. Appeals for aid did not fall on deaf ears; France, which had replaced the reactionary monarchy of Charles X with the liberal monarchy of Louis-Philippe in 1830, was sympathetic to the Cristino cause. The Whig governments of Viscount Melbourne were similarly friendly, and organized volunteers and material aid for Spain. Still confident of his successes, however, Don Carlos joined his troops on the battlefield. While Zumalacárregui agitated for a campaign to take Madrid, Carlos ordered his commander to take a port on the coast. In the subsequent campaign, Zumalacárregui died after being shot in the calf. There was suspicion that Carlos, jealous of his general's successes and politics, conspired to have him killed.
