Walker now returned to San Juan, where he picked up a few recruits from among the ranks of homeward-bound Americans on the steamer from California. Here also he learned of the death of Castellon, who had fallen a victim to the cholera. His successor, Don Nasario Escoto, warmly congratulated Walker on his success at Virgin Bay, and promised further aid. Learning from intercepted letters of the authorities at Granada that the city was in an almost defenceless condition, he determined to attack the Legitimist stronghold without awaiting the advance of Corral, who had replaced Guardiola in the command of the enemy. To show his contempt of the latter, he sent the intercepted correspondence to the Legitimist headquarters, and was not a little surprised at receiving a polite acknowledgement of the courtesy, and a hieroglyphic document from Corral, which proved to consist of Masonic signs. A freemason in the Falange, De Brissot, interpreted them to mean an overture for confidential negotiations. No reply was made to the proposition. Recruits continued to flock to the Democratic standard. Colonel Charles Gilman, a one-legged veteran of Sonora, came down with thirty-five men from California. The native allies now numbered about two hundred and fifty. Two small cannon were procured and mounted. By the 11th of October Walker had everything in readiness for his most audacious stroke, the capture of Granada, a city as dear to the Legitimist cause, and especially to its proud inhabitants, as was its namesake to the Moors of old Spain. Corral was massing his forces at Rivas, hoping, yet fearing, to meet his enemy on the Transit road. No suspicion of an attack on the capital seems to have entered his mind. Dissension was rife in the Legitimist camp, Guardiola and Corral quarrelling for the supreme command. The native Democrats on the other side, whatever of jealousy they may have felt towards their foreign allies, carefully veiled their feelings and made a show of the utmost cordiality. Walker enforced absolute discipline without distinction of nationality, a spice of grim humour sometimes seasoning his decisions. Two native officers, having quarrelled all night over some old or new feud, were ordered to settle the affair by going out and fighting a duel next morning, but their courage had oozed away by daybreak, and the trouble was heard of no more.
