The Philippine-American War, which broke out in 1899, was a conflict that fundamentally changed the future of the Philippines. At its core, the war was a struggle between a burgeoning Filipino independence movement and a United States government eager to expand its influence.
One of the most significant phases of this war was fought in the suburbs of Manila, particularly between the capital and Lake Laguna de Bay. Here, U.S. forces, bolstered by reinforcements from the mainland, launched an aggressive campaign to cut off Filipino communication lines and seize strategic locations.
This article delves into key battles in this critical phase of the war and examines the strategies, challenges, and personalities on both sides.
U.S. Strategy: Cutting Off Aguinaldo’s Army
By early 1899, Maj. Gen. Elwell S. Otis, the commanding officer of U.S. forces in the Philippines, was determined to break the back of the Filipino resistance. His strategy was to clear the territory between Manila and Lake Laguna de Bay, aiming to isolate Emilio Aguinaldo’s forces in the north from those in the south. Otis believed that a successful campaign would effectively divide Luzon and bring the conflict to a swift conclusion.
- U.S. troop strength: At the start of the campaign in February 1899, U.S. forces in the Philippines numbered 20,851 soldiers. However, by the time hostilities had reached their peak in 1900, this number had swelled to 71,727 enlisted men and 2,367 officers. By the end of the war, a total of 126,468 American soldiers had served in the Philippines.
- The role of Filipino scouts: From September 1899, the U.S. Army began recruiting Filipinos from various ethnic groups to serve as scouts. These regional units, composed of Ilocanos, Cebuanos, and other ethnicities, were later integrated into the Philippine Scouts in 1901, playing a key role in the U.S. military’s operations.
The Challenges Facing Filipino Forces
While Filipino forces were initially formidable, their resources quickly became stretched thin as the war continued. Aguinaldo’s army, numbering around 20,000 men at the start of the war, possessed about 15,000 rifles. However, many of these rifles malfunctioned or were captured by U.S. forces, leaving the Filipinos with an ever-dwindling supply of firearms. Ammunition was another significant challenge, and Filipino soldiers were often forced to manufacture their own gunpowder. Unfortunately, the homemade powder was far less effective than standard ammunition and produced thick black smoke, making it easier for U.S. troops to locate Filipino positions.
Despite these setbacks, the Filipino infantry was known for its toughness. They required minimal supplies and were well-adapted to the difficult terrain of the Philippine countryside. However, the army’s poor training and weak officer corps presented serious challenges. In addition, internal divisions among political and military leaders, often along regional lines, hampered the unity of the Filipino resistance. While facing a well-equipped and better-trained enemy, Filipino leaders also found time to engage in personal disputes, which further weakened their efforts.
The American Forces: Veterans of the Indian Wars
A significant portion of the U.S. military leadership in the Philippines had previously served in the Indian Wars in the American West. Of the 30 American generals who served in the Philippines between 1898 and 1902, 26 had fought in the Indian Wars. These veterans brought with them experience in unconventional warfare, which proved valuable in the conflict with Filipino guerrilla fighters. However, this experience also contributed to the often brutal methods employed by U.S. forces during the war.
The U.S. forces were not without their own challenges. The tropical environment of the Philippines was unfamiliar to most American soldiers, many of whom came from colder climates. Diseases such as malaria and dysentery took a significant toll on U.S. forces, killing far more men than combat did.
Key Battles in the Suburbs of Manila
The Battle of Guadalupe Church (March 13, 1899)
The Battle of Guadalupe Church marked one of the early engagements in the U.S. campaign to clear the Manila suburbs. The official U.S. report listed three Americans killed and 25 wounded, while Filipino casualties were estimated at around 200. The battle demonstrated the increasing intensity of the conflict, as both sides sought to control strategic locations around Manila.
The Battle of Pateros (March 14, 1899)
On March 14, 1899, a battalion from the 1st Washington Volunteer Infantry attacked the town of Pateros under the command of Maj. John J. Weisenburger. The Americans crossed a river and stormed Filipino entrenchments, setting the town ablaze during the attack. Despite suffering one killed and five wounded, the Americans successfully forced the Filipino forces to retreat. Filipino casualties were not recorded but were likely significant given the intensity of the battle.
The Battle of Pasig (March 15, 1899)
Brig. Gen. Loyd Wheaton led a Provisional Brigade consisting of infantry, artillery, and cavalry units in an assault on Pasig. This marked the first organized U.S. campaign against the Filipinos in the suburbs of Manila.
- American forces involved: The brigade included the 20th Infantry, 22nd Infantry, two battalions from the 1st Washington Volunteer Infantry, seven companies from the 2nd Oregon Volunteer Infantry, one platoon from the 6th Artillery, and three troops from the 4th Cavalry.
- Casualties: U.S. losses were light, with one soldier killed and three wounded. The New York Times reported that American forces discovered 106 dead Filipinos and 100 fresh graves near Pasig. They also captured 175 Filipino prisoners. A separate American report estimated Filipino casualties at 400.
Despite the defeat, Filipino forces continued to harass the American garrison in Pasig, utilizing guerrilla tactics to frustrate their occupiers.
The Battle of Cainta (March 16, 1899)
In Cainta, Maj. William P. Rogers and the 3rd Battalion of the 20th U.S. Infantry Regiment faced a Filipino force numbering around 1,000. After a fierce battle, the Filipinos retreated, and Rogers ordered the town to be burned. American casualties included two killed and 14 wounded, while Filipino casualties were estimated at around 100.
A notable event in Cainta was the attempted assassination of Exequiel Ampil, the town’s Presidente Municipal and a former member of the Katipunan who had become a supporter of the Americans. After advising Filipino forces to surrender, Ampil was shot by his own countrymen but managed to escape and survive the war.
The Battle of Taguig (March 18-19, 1899)
The Battle of Taguig saw U.S. forces, including the 22nd U.S. Regular Infantry, 1st Washington Volunteers, and 2nd Oregon Volunteers, engage Filipino troops under the command of Gen. Pio del Pilar. The battle resulted in three American deaths and 17 wounded, while Filipino losses were estimated at 75 killed. Del Pilar, who had distinguished himself in the earlier revolution against Spain, struggled against the better-equipped and more experienced American forces.
Del Pilar, like many Filipino generals, found it difficult to match the Americans’ superior firepower and training. His troops were often outgunned and outmaneuvered, leading to heavy losses. Despite his setbacks, Del Pilar remained a significant figure in the Filipino resistance until his capture in 1900.
The Massacre at Taytay (March 19, 1899)
One of the most horrific events of the Philippine-American War occurred in the town of Taytay. After an American soldier was found murdered, Brig. Gen. Loyd Wheaton ordered a brutal retaliation. U.S. troops burned the town and were instructed to kill any Filipinos they encountered. An estimated 1,000 men, women, and children were slaughtered in the massacre, reflecting the often brutal nature of the conflict.
In a letter to his brother, A.A. Barnes of Battery G, 3rd Artillery, described the events: “Last night one of our boys was found shot and his stomach cut open. Immediately orders were received from General Wheaton to burn the town and kill every native in sight, which was done…About one thousand men, women and children were reported killed. I am probably growing hard-hearted for I am in my glory when I can sight my gun on some dark skin and pull the trigger.”
The massacre at Taytay was just one example of the many atrocities committed during the war. Such incidents contributed to the long-lasting resentment between the Filipino people and the United States, even after the war’s official end in 1902.
The Legacy of Pio del Pilar
General Pio del Pilar, born Pio Castañeda on July 11, 1865, in what is now Makati City, played a prominent role in both the revolution against Spain and the subsequent war against the United States. A member of the Katipunan, he adopted the name “Del Pilar” to protect his family from Spanish authorities. During the revolution, Del Pilar formed a chapter of the Katipunan called Matagumpay (Triumphant) and took on the symbolic name Pang-una (Leader).
Del Pilar was instrumental in convincing Emilio Aguinaldo to order the execution of Andres Bonifacio, a decision that remains controversial in Filipino history. Despite his role in Bonifacio’s death, Del Pilar continued to serve the revolutionary cause and was appointed chief of the “Second Zone of Manila” by Gen. Antonio Luna in 1899.
After his capture in 1900, Del Pilar briefly swore allegiance to the United States but continued to work for the Filipino guerrilla resistance. He was rearrested and deported to Guam in 1901, alongside prominent figures such as Apolinario Mabini. Del Pilar returned to the Philippines in 1903 and lived until 1931, when he died at the age of 65. Today, he is commemorated as a hero in Makati City, with a monument in his honor standing at the intersection of Paseo de Roxas and Makati Avenue.
The Impact of the Battles in Manila’s Suburbs
The battles fought in the suburbs of Manila were crucial in shaping the course of the Philippine-American War. While the U.S. military achieved significant victories, Filipino forces demonstrated remarkable resilience, despite being outgunned and outnumbered. The conflict was marked by brutality on both sides, including massacres such as the one at Taytay, which left a lasting scar on the Filipino psyche.
The campaign in Manila’s suburbs showcased the complexities of the Philippine-American War, with both sides enduring significant challenges. For the Filipinos, it was a fight for independence and survival. For the Americans, it was a campaign to expand their influence and control in the Pacific. The legacy of these battles continues to influence Philippine-American relations to this day.
