Dong Re Lao Mountain

Dong Re Lao Mountain is located at 16°18′14″N 107°14′52″E / 16.3038°N 107.2479°E / 16.3038; 107.2479 in the A Shau Valley, Vietnam, near the Laotian border.

It is densely forested and rises to 4,879 feet (1,487 m), just north of A Luoi, a former French airfield.

In April 1968, during the Vietnam War, the mountain was the site of an intense battle between members of the American 1st Cavalry Division, long-range reconnaissance patrol troops, and the North Vietnamese Army.

[1] The mountain was dubbed "Signal Hill" by headquarters as it served as the lone radio relay site for American forces fighting in the valley during Operation Delaware.
