By a veteran of Lt. Col. Merritt A. Edsons battalion, and author of the Dick Winters biography Biggest Brother and coauthor of A Higher CallOn the killing ground that was the island of Guadalcanal, a 2,000-yard-long ridge rose from the jungle canopy. Behind it lay the all-important air base of Henderson Field. And if Henderson Field fell, it would mean the almost certain death or capture of all 12,500 marines on the island . . .But the marines positioned on the ridge were no normal fighters. They were tough, hard-fighting men of the Edsons Raiders an elite fighting unit within an already elite U.S. Marine Corps. Handpicked for their toughness, and submitted to a rigorous training program to weed out those less fit, they were the Marine Corpss best of the best.
