The Battle of la Drang
In the first major engagement of the war between regular U.S. and North Vietnamese forces, Col. Tony Nadal and his fellow 3rd Brigade, 1st Calvary Division (Airmobile) launched the first heliborne assault of its kind against the North Vietnamese forces. This three day battle resulted in the loss of thousands of lives, and tested the limits of both armies capabilities. It was later depicted in the book and film We Were Solders Once.
