1960: The nuclear-powered radar picket submarine USS Triton (SSRN-586) returns to port after completing the first-ever completely submerged circumnavigation of the Earth. Skippered by Capt. Edward L. Beach Jr. – a Navy Cross recipient and best-selling author of “Run Silent, Run Deep” – Triton has followed a trek closely paralleling that of the first-ever global circumnavigation led by Portugese Capt. Ferdinand Magellan in the 16th century. The submarine covers the 26,723 nautical mile journey in just 60 days and 21 hours, averaging 19 knots.

1969: (Feature Image) Soldiers of the 101st Airborne Division move into the A Shau Valley for what would become an intense ten-day battle against North Vietnamese Army on Hill 937 – dubbed “Hamburger Hill.” The Americans charge up the steep slopes 11 times before dislodging the heavily fortified defenders. Although the U.S. forces inflict heavy casualties on the communists and survivors retreat into Laos, the U.S. military abandons the hill, which is retaken by the NVA four weeks later.
Following Hamburger Hill, the White House instructs its military commanders to avoid engagements that result in large American casualties as public support is dwindling for the war.
