From: The Coldest Winter: America and the Korean War, by David Halberstam (Hyperion, 2007), pp. 499-501:
More than most senior American commanders of his era, Matt Ridgway had a passion for intelligence. The American Army had always taken its intelligence functions somewhat casually; the men assigned to intelligence duty tended to have been passed over in their careers, not quite good enough for the prized command positions. Often the lower ranks in the Army’s intelligence shop were very good, but their superiors were not respected by their peers. Perhaps it was the nature of the modern American Army—it had so much force and materiel that when it finally joined battle, intelligence tended to be treated as a secondary matter, on the assumption that any enemy could simply be outmuscled and ground down.
There were a number of reasons for Ridgway’s obsession with intelligence. Some of it was his own superior intellectual abilities; he was simply smarter than most great commanders. Some of it was his innate conservatism, his belief that the better your intelligence, the fewer of your own men’s lives you were likely to sacrifice. A great deal of it was his training in the airborne, where you made dangerous drops behind enemy lines with limited firepower and were almost always outnumbered and vulnerable to larger enemy forces…. George Allen—who as a young CIA field officer in Vietnam briefed Ridgway daily for several weeks as the French war in Indochina was coming to its climax in 1954, later said he had never dealt with a man so acute and demanding, not even Walter Bedell Smith, who had been Dwight Eisenhower’s tough guy in Europe and later took over the CIA. Ridgway’s sense of the larger picture was so accurate, Allen believed, because of his determination to get the smallest details right. It was Ridgway’s subsequent report on what entering the war in Indochina would mean—five hundred thousand to one million men, forty engineering battalions, and significant increases in the draft—that helped keep America out of the war for a time….
The CIA, blocked from the Korean theater by MacArthur and Willoughby, was soon welcomed back. Starting at Eighth Army headquarters and running through the command, there was going to be a healthy new respect for the enemy. The Chinese had identifiable characteristics on the battlefield. They also had good, tough soldiers. Some units were clearly better than others, some division commanders better than others, and it was vital to know which these were and where they were. Now Ridgway intended to study them. There would be no more windy talk about the mind of the Oriental. The questions would be: How many miles can they move on a given night? How fixed are their orders once a battle begins? How much ammo and food do they carry into each battle—that is, how long can they sustain a given battle? Ridgway was going to separate battlefield realities from theoretical discussions about the nature of Communism. The essential question was: How exactly can we tilt the battlefield to our advantage?
Ridgway now intended to play at least as big a role in the selection of the battlefield as his Chinese opposites. For a time, he started his day by getting in a small plane and, with Lynch at the controls, flying as low as they could, looking for the enemy. With that many Chinese coming at his army, there had to be signs of them, evidence that they existed, but he saw almost nothing. That he found nothing did not, as had happened in November after Unsan, create a lack of respect for them—rather it brought greater respect for the way they could move around seemingly invisible. Gradually Ridgway began to put together a portrait of who the Chinese were and how they fought—and so, how he intended to fight them. The Chinese were good, no doubt about that. But they were not supermen, just ordinary human beings from a very poor country with limited resources. Not only did the Chinese operate from a large technological disadvantage, they had significant logistical and communications weaknesses. The bugles and flutes announcing their attacks could be terrifying in the middle of the night, but the truth was that, with only musical instruments, they could not react quickly to sudden changes on the battlefield. If they had a breakthrough, they often lacked the capacity to exploit it immediately. That was a severe limitation; it meant that a great deal of blood might be shed without their getting adequate benefits. In addition, certain logistical limitations were built into any attack they made—the ammunition and food they could carry was finite indeed. The American Army could resupply in a way inconceivable to the Chinese and so could sustain a given battle far longer.
Ridgway spent his first few weeks in country pressing everyone for information about the Chinese fighting machine. By the middle of January, he felt he knew much of what he needed to know. This war, he decided, was no longer going to be primarily about gaining terrain as an end in itself, but about selecting the most advantageous positions available, making a stand, and bleeding enemy forces, inflicting maximum casualties on them. The key operative word would be “pyrrhic.” What he now sought was an ongoing confrontation in which every battle resulted in staggering losses for the Chinese. At a certain point, even a country with a demographic pool like China’s had to feel the pain from the loss of good troops. He wanted to speed up that moment, to let his adversaries know that there were no more easy victories out there for the picking, no second shot at a big surprise attack. If the war was to be a grinder then the great question was: which side would do the more effective job of grinding up the other?
The first thing Ridgway realized was that it was a disaster to retreat once the Chinese hit. The key to their offensive philosophy was to stab at a unit, create panic, and then, from advantageous positions already set up in its rear, maul it when it retreated. All armies are vulnerable in retreat, but an American unit, because of all its hardware, condemned to the narrow, bending Korean roads, was exceptionally so. What the Chinese had done at Kunuri, Ridgway learned, matched their MO when they fought the Nationalists in their civil war. But no one, it appeared, had been paying much attention. The disaster at Kunuri, he believed, had not been writ so large because the Chinese were such magnificent soldiers or even had such an overwhelming advantage in manpower. Even as far north and as vulnerable as they were, if the American units had been well buttoned down at night, if each unit had had interlocking fields of firepower with reliable flanking units (and had not counted on the ROKs to protect them), the outcome of the battle might have been different. Even at Kunuri, the military had had the capacity to resupply the troops by air until the Chinese were exhausted. Ridgway’s long training as an airborne man was critical to the strategy he sought now. He meant to create strong islands of his own, sustain unit integrity with great fields of fire, and then let the enemy attack. It was, he believed, why Colonel John Michaelis, with his Twenty-seventh Regiment Wolfhounds, had been so much more successful than other regimental commanders in the early part of the war. Michaelis was an airborne guy, and he did not mind if his men were cut off as long as unit integrity was preserved. He knew he could always be resupplied by air.
What Ridgway wanted to do was start the Eighth Army moving north again—for reasons of morale as much as anything.
