I fear that for many young Americans the word "Guadalcanal" means nothing.
Guadalcanal is an island in the Solomons named after a village in the province of Seville, Spain. The island was named by the Spanish explorer Álvaro de Mendaña in 1568, for the village which was the birthplace for a member of Mendaña's expedition.
In 1942 this island was the scene for the beginning of the end of the Japanese Empire.
At Guadalcanal, the Empire of Japan lost two-thirds of their 31,000-plus army troops committed to the fight. Approximately 1,600 Americans were killed. Warship losses were roughly equal, but the Japanese would never equal American industrial ability to replace them and so felt the loses more significantly. Most devastating to the Japanese was the decimation of their elite naval aviators. From this, they would never recover. The most shocking of American losses was the over 5,000 U.S. sailors and Naval officers killed, a figure that easily surpassed the Navy’s accumulated losses in all her history.More here.
