“Here we go, I said to myself as my system electrified with the familiar rush of adrenaline.”   On July 18, 1967, Staff Sergeant James Donahue and the men of Special Forces Detachment A-304 were on an operation; code-name Blackjack-34. Their mission: to find and engage an enemy battalion that was thought to be operating in an enemy-controlled area north of Quon Loi, Vietnam.   Now Donahue bears witness to the horrific events of that day and the exceptional grit and heroism of his teammates. Blackjack-34 is a magnificent tribute to the warriors of the Mobile Guerrilla Force―their courage and willingness to press on, no matter what the odds.
