After halting a short time at Managua, Belloso continued to advance; and at Nindiri, a league from Masaya, he was joined by Martinez and his followers from Chontales and Matagalpa, thus swelling the allied force to twenty-two or twenty-three hundred men. The moral condition of the command at Masaya was such that McIntosh received orders to retire on Granada; and the state of his men may be judged from the manner in which they left Masaya. Such was the haste and confusion that Capt. Henry was left behind, and his safety was the result of accident, being due to the good-will of the women who attended him during his illness. A brass six-pounder was left on the road, about three miles out of Masaya, and the enemy afterward got possession of it. McIntosh might have been deliberate, even slow in his movement with entire safety; for Belloso did not enter Masaya for some hours after it was abandoned by the Americans. Walker, had he desired it, might probably have prevented for a time, or at least much embarrassed the junction of Martinez with Belloso. But a war against scattered guerillas was more exhausting to the Americans than a contest with the enemy gathered in masses. The Allies were less formidable when united than when acting in detached bodies at several distant points. Hence, no obstacle was put in the way of Martinez in his march toward Belloso. In fact, the best manner of treating a revolutionary movement in Central America, is to treat it as a boil, let it come to a head, and then lance it, letting all the bad matter out at once. It was an object for the Americans to let all the dissatisfied elements in Nicaragua gather about the Allied force, so that the question at issue might be decisively determined. The accession of Martinez really added little, if any, to Belloso’s military strength. Meanwhile the force in Granada was increased by the arrival, on the 4th of October, of Col. Sanders, with Capt. Ewbanks, and about seventy recruits from California. Three days after, Col. John Allan landed with nearly one hundred fresh men; and at the same time two twelve-pound mountain howitzers, with a small supply of shells, and four hundred Minié rifles were received from New-York. By some blunder, however, the carriages of the howitzers did not accompany them; and several days elapsed before Capt. Schwartz was able to have temporary carriages prepared. The arrival of the howitzers and shells had been anxiously expected, since it was hoped with their aid to drive the enemy more readily from the towns they were in the habit of barricading with adobes, thus making it difficult to carry them by assault, unless with the loss of large numbers of men.
