A look back at the Greatest Generation, presented by Getty Images.

On Oct. 20, 1944, Gen. Douglas MacArthur waded ashore to the Philippines island of Leyte with the declaration, “People of the Philippines, I have returned!”

Nearly two years earlier, MacArthur and his family had been forced to flee the Philippines as an invading Japanese army took hold of the region. To the thousands of Filipino and American personnel left behind, Gen. MacArthur vowed, “I shall return.”

This march was named the Bataan Death March because of the high number of brutal and gruesome deaths along the road at the hands of the Japanese.

The following months proved to be among the most bloody confrontations of World War II.
