# 51st Coast Artillery Regiment

The 51st Coast Artillery Regiment was a Coast Artillery regiment in the United States Army.

## History

The 51st Coast Artillery Regiment was a United States Army regiment that was activated in 1917 during World War I. The regiment was primarily responsible for defending the coast of the United States against enemy attacks, and it served in this role until the end of the war.
After the war, the 51st Coast Artillery Regiment was stationed at various locations in the United States, including Fort MacArthur in California and Fort Sheridan in Illinois. In 1941, the regiment was stationed at Fort Mills in the Philippines, where it played a critical role in the defense of the islands against the Japanese during World War II.
During the Japanese invasion of the Philippines in December 1941, the 51st Coast Artillery Regiment provided crucial support to the defenders of the islands. The regiment's soldiers manned coastal defense guns, anti-aircraft guns, and other weapons, and they played a key role in repelling the initial Japanese attacks. However, as the Japanese continued to advance, the regiment was forced to retreat to the Bataan Peninsula, where it continued to fight alongside other American and Filipino units.
In April 1942, after months of fierce fighting, the 51st Coast Artillery Regiment and the other defenders of Bataan were forced to surrender to the Japanese. The soldiers of the regiment were taken prisoner and sent to various prison camps throughout the Philippines and Japan. Many of these soldiers endured brutal treatment at the hands of their captors, including forced labor and starvation.
After the war, the surviving members of the 51st Coast Artillery Regiment returned home and were honored for their service. Today, the regiment is remembered as one of the units that fought bravely during the defense of the Philippines, and its legacy lives on in the soldiers who continue to serve in the United States Army today.
