The "Battle of Aliaga" was fought on September 5–6, 1897, between the Philippine revolutionaries of Nueva Ecija and the Spanish forces of Governor General Primo de Rivera. It is often described as one of the "most glorious battles" of the Philippine Revolutionary War.

With Aguinaldo's forces pushed out of Cavite, Aguinaldo and his forces retreated to Puray, Montalban and eventually found his way to central Luzon. Retreating to the caves of Biak-na-bato, he began to negotiate the peace pact known as the Pact of Biak-na-Bato. However, after the Spaniard's pursuit on the central Luzon many of the rebels died down, generals like Manuel Tinio and Mariano Llanera opted to continue fighting. On August 27, 1897, Gen. Mamerto Natividad and Col. Manuel Tinio conducted raids in Carmen, Zaragoza and Peñaranda, Nueva Ecija. Three days later, on the 30th, they stormed and captured Santor (now Bongabon) with the help of the townspeople. They stayed in that town till September 3.

On September 4, with the principal objective of acquiring provisions lacking in Biac-na-Bato, Gen. Natividad and Col. Manuel Tinio united their forces with those of Col. Casimiro Tinio, Gen. Pio del Pilar, Col. Jose Paua and Eduardo Llanera for a dawn attack on Aliaga. (Casimiro Tinio, popularly known as ‘Capitan Berong', was an elder brother of Manuel through his father's first marriage.) The following morning was described as "The most glorious battle of the rebellion". The rebel forces, numbering about between 20,000-30,000 men, took the church and convent, the Casa Tribunal and other government buildings. The commander of the Spanish detachment died in the first moments of fighting, while those who survived were locked up in the thick-walled jail. The rebels then proceeded to entrench themselves and fortify several houses. The following day, Sunday the 5th, the church and convent as well as a group of houses were put to the torch due to exigencies of defense.
