By May 1898, the army had about 12,000 troops. The battle of Alapan was Gen. Emilio Aguinaldo's first victory after returning from overseas (Singapore) on May 19, 1898. The Alapan I Elementary School now stands on the site of the battle.


The Filipino national flag was hoisted for the first time after the victory in Alapan. The flag was unfurled by Aguinaldo at the Teatro Caviteno in Cavite Nuevo (now Cavite City) on May 28 before victorious Filipino revolutionists and more than 270 captured Spanish marines. A large group of officers and men of the U.S. Asiatic Squadron under Admiral George Dewey witnessed the unfurling ceremony. The flag was designed by General Emilio Aguinaldo and sewn at 535 Morrison Hill, Hong Kong by Mrs. Marcela Marino Agoncillo - wife of the first Filipino Diplomat, Felipe Agoncillo, with the help of her daughter Lorenza and Mrs. Delfina Herbosa Natividad, niece of Dr. Jose P. Rizal and wife of Gen. Salvador Natividad.



General Aguinaldo said of that encounter: "There it was that the first engagement of the Revolution of 1898 took place. The battle raged from ten in the morning to three in the afternoon, when the Spaniards ran out of ammunition and surrendered, with all their arms, to the Filipino revolutionists, who took their prisoners to Cavite. In commemoration of this glorious achievement, I hoisted our National Flag in the presence of a great crowd, who greeted it with tremendous applause and loud, spontaneous and prolonged cheers for independence."

General Leopoldo Garcia Pena, the Spanish military commander of Cavite with 2,800 Spanish troops scattered in various detachments in Cavite Province, was hardpressed by the combined forces of Generals Luciano San Miguel, Mariano Noriel, Artemio Ricarte and Juan Cailles who have between them about 6,000 - 8,000 troops.

A column of 500 infantrymen was rushed from Manila to reinforce Pena but was crushed by another combined force in Laguna under Generals Paciano Rizal and Pio del Pilar. By nightfall of May 31, the whole province of Cavite fell into the hands of the revolutionaries. General Pena himself and his surviving troops were made prisoners.
