A Vanishing Breed centers on Doyle’s continuing struggle to find inner peace, and his on-again off-again relationships,
but also examines the question of what compels all volunteers to respond. Doyle’s inner demons provoke him to action, but the men with whom he serves make no less a sacrifice.
In 1983, in war-torn Lebanon, Robert J. Doyle ordered the complete destruction of an unsuspecting village. As he walked through the carnage later, he vowed one day he would somehow pay off the loss of innocent lives.
