Cause

During the Spanish–American War, the United States sought to seize Spanish colonial possessions in the Pacific. Guam, a Spanish-held island, was strategically targeted. The isolated garrison had received no news of the outbreak of war and possessed neither the knowledge nor the military strength to mount any meaningful defense.

Event

The U.S. Navy dispatched a single cruiser, USS Charleston, to Guam. Upon arrival, American forces encountered a Spanish garrison unaware that a state of war existed. The Spanish offered no resistance and surrendered without a single shot fired, making the capture entirely bloodless.

Consequence

Guam passed into American control following the surrender, and the United States retained the island as a territory. The capture represented the sole military action of the Spanish–American War on Guam and established American presence in the western Pacific that persists to the present day.
