Alcatraz and the Philippine-American war
The Spanish-American War ended fairly quickly, with a peace protocol in August and the Treaty of Paris signed on December 10th, but the fighting was just beginning. Spain and the United States excluded any Filipino representation from the treaty congress, and Spain ceded the Philippines to the United States. Many Filipinos, having already started a revolution for independence from Spanish imperial rule, objected to this switch-up of imperial powers. In early 1899, the Philippine-American War began.

This change from liberating a Spanish colony to fighting to rule it demoralized many U.S. soldiers. The U.S. entered the war with the idea that it was helping spread civilization and remove Spanish oppression from the Philippines. Now, fighting the very people the soldiers had been sent to help, things changed. Along with the shocking brutality of the war, desertion became a major problem. Suddenly, hundreds of soldiers were sent back to San Francisco to serve time for desertion and other crimes.
While not an official military prison yet, Alcatraz had been housing military prisoners since the 1860s and was designated during the war as the place to incarcerate all the prisoners returning from the Philippines. The prison population at the post on Alcatraz Island soared into the hundreds, and a new prison complex was built on the parade ground.

Frank Kinne arrived on the island in 1900 for a 15-year sentence of desertion and treason. He had left his regiment and began fighting for the Filipino nationalists. He was sent to Alcatraz after he was caught leading a group of fighters. A few months after Kinne started his sentence, he and two other men escaped from the hospital building by faking sick and then sneaking out and taking a boat.
While we don’t know exactly what motivated Frank Kinne to fight for the Filipino people, many soldiers felt conflicted in the midst of a changing war. One soldier from Kansas wrote of the Filipino people, “Their independence is dearer to them than life, as ours was in years gone by, and is today... there is not a man who enlisted to fight these people, and should the United States annex these islands, none but the most bloodthirsty will claim himself a hero. This is not a lack of patriotism, but my honest belief.”
The war sealed Alcatraz’s fate: in 1907 the island officially became a military prison, and they constructed the cellhouse soon after. The rest is, as they say, history. From far away disputes to moral dilemmas to local change, how have global events impacted your daily life?
