Four companies of the 1st Colorado advanced across the fields, entered the Spanish trenches, crossed the bridge, and moved up the road, the Spaniards still keeping up an ineffective fire from long range.
The 3rd Colorado came up with a band of music, and then the whole regiment deployed in skirmishing order and maintained a continual rifle fire until they halted on the Luneta Esplanade. The band took up a position in an old Spanish trench and played as the troops filed past along the beach. The Spaniards were gradually falling back on the city, and the rebels who were located near the Spanish lines continued the attack; but the Americans gave them the order to cease firing, which they would not heed. The Americans thereupon turned their guns upon the rebels, who showed an inclination to fight. Neither, however, cared to fire the first shot; so the rebels, taking another road, drove the Spaniards, in confusion, as far as Ermita, when Emilio Aguinaldo ordered his men to cease firing as they were just outside the city walls. The rebel commander had received strict orders not to let his forces enter Manila. The American troops then developed the attack, the Spaniards making, at first, a stubborn resistance, apparently for appearanceʼ sake, for the fight soon ended when the Spaniards in the city hoisted the white flag on a bastion of the old walls. Orders were then given to cease firing, and by one oʼclock the terms of capitulation were being negotiated. General F. V. Greene then sent an order to the troops for the rear regiments to muster on the Luneta Esplanade, and there half the American army waited in silent expectation. The Spanish entrenchments extended out from the city walls in different directions as far as three miles. The defenders were about 2,500 in number, composed of Spanish regular troops, volunteers, and native auxiliaries; about the same number of troops being in the hospitals inside the city. The opponent force amounted to about 15,000 rebels and 10,000 Americans ashore and afloat. The attacking guns threw heavier shot and had a longer range than the Spanish artillery. The Americans were also better marksmen than the Spaniards. They were, moreover, better fed and in a superior condition generally. The Americans were buoyed up with the moral certainty of gaining an easy victory, whereas the wearied Spaniards had long ago despaired of reinforcements coming to their aid; hence their defence in this hopeless struggle was merely nominal for “the honour of the country.”
For some time after the white flag was hoisted there was street-fighting between the rebels and the loyals. The rattle of musketry was heard all round the outskirts. The rebels had taken 300 to 400 Spanish prisoners and seized a large quantity of stores. General Basilio Augusti, who was personally averse to useless bloodshed, relinquished his command of the Colony about a week prior to the capitulation. Just before the attack on the city he went on board a German steam-launch which was waiting for him and was conveyed to the German cruiser Kaiserin Augusta, which at once steamed out of the bay northwards. General Fermin Jaúdenes remained as acting-Captain-General.[13] Brig.-General of Volunteers and Insp.-General Charles A. Whittier and Lieutenant Brumby then went ashore in the Belgian Consulʼs launch, and on landing they were met by an interpreter, Cárlos Casademunt, and two officers, who accompanied them to the house of the acting-Captain-General, with whom the draft terms of capitulation were agreed upon. In his evidence before the Peace Commission at Paris, General Whittier said: “I think the Captain-General was much frightened. He reported in great trepidation that the insurgents were coming into the city, and I said that I knew that that was impossible because such precautions had been taken as rendered it so. “His fear and solicitude about the natives entering the city when I received the surrender of Manila were almost painful to witness.” Lieutenant Brumby returned to Admiral Dewey to report, and again went ashore with General Merritt. In the meantime General Jaúdenes had taken refuge in the sacristy of a church which was filled with women and children, presumably with the wise object of keeping clear of the unrestrained mobs fighting in the suburbs. For some time the Spanish officers refused to reveal his whereabouts, but eventually he and General Merritt met, and on August 14 the terms of the Capitulation were signed between General Nicolás de la Peña y Cuellas and Colonels Jose Maria Olaguer Tellin and Cárlos Rey y Rich, as Commissioners for Spain, and Generals F. V. Greene and Charles A. Whittier, Colonel Crowder, and Captain Lamberton, U.S.N., as Commissioners for the United States. The most important conditions embodied in the Capitulation are as follows, viz.:
1. The surrender of the Philippine Archipelago.
2. Officers to be allowed to retain their swords and personal effects, but not their horses.
3. Officers to be prisoners of war on parole.
4. The troops to be prisoners of war and to deposit their arms at a place to be appointed by General Merritt.
5. All necessary supplies for their maintenance to be provided from the public Treasury funds, and after they are exhausted, by the United States.
6. All public property to be surrendered.
7. The disposal of the troops to be negotiated, later on, by the United States and Spanish Governments.
