On this day in 1969 the battle for Ap Bia Mountain occurred during the Vietnam "incident". (It was never a declared war kiddies, haven't had one of those since WWII). Also known as "hamburger hill" because of the high casualty rate. The US and South Vietnamese troops were trying to stop troop movements along the Ho Chi Mihn trail into Laos. Although a victory for the US, it gave the North Vietnamese Army (NVA) more resolve to resist.
Finally on this day in 1963 the Beatles started a phenomenal 30 week run at the top of the charts with their album "Please Please Me". This just so happens to be the longest run at #1 by an album ever.
