Bataan Death March begins

The day after the surrender of the main Philippine island of Luzon to the Japanese, the 75,000 Filipino and American troops captured on the Bataan Peninsula begin a forced march to a prison camp near Cabanatuan. During this infamous trek, known as the “Bataan Death March,” the prisoners were forced to march 85 miles in six days, with only one meal of rice during the entire journey. By the end of the march, which was punctuated with atrocities committed by the Japanese guards, hundreds of Americans and many more Filipinos had died.

Paul McCartney announces the breakup of the Beatles

The legendary rock band the Beatles spent the better part of three years breaking up in the late 1960s, and even longer than that hashing out who did what and why. And by the spring of 1970, there was little more than a tangled set of business relationships keeping the group together. Each of the Beatles was pursuing his musical interests outside of the band, and there were no plans in place to record together as a group. But as far as the public knew, this was just a temporary state of affairs. That all changed on April 10, 1970, when an ambiguous Paul McCartney “self-interview” was seized upon by the international media as an official announcement of a Beatles breakup.
