Lessons from Operation Cobra

The first phase of Operation Cobra ended with the complete destruction of the left flank of the German army. This enabled the First Army to move south to widen the gap and outflank the Germans south of Saint-Lô.

The comparison between this operation and the operations in the
bocage
country, south of Airel, was astonishing. Previously, it had taken twelve days to penetrate eight miles. Including the operation around Villiers-Fossard, our total tank losses had been eighty-seven. In the first phase of Operation Cobra, from the morning of July 26 through July 28, the division moved forward seventeen miles to Coutances with a loss of only two tanks.

The lessons were straightforward. The hedge choppers, although we had fewer than half of those ordered, allowed the tanks to break through the hedgerows at a number of points simultaneously without forewarning the Germans. Next, we had the almost perfect classroom solution of air, armor, infantry, and artillery working in support of one another. The crushing firepower completely destroyed enemy troops in the area and neutralized their reserves. This kept the flanks open long enough for the armor to secure a complete breakthrough.

The armored division is in its ideal element once it is through the main line of resistance and has a more or less open field. Here it can move rapidly, bypass pockets of enemy resistance, and keep casualties at a minimum. Conversely, when it gets bogged down and moves slowly, casualties reach a maximum. Operation Cobra will be remembered as one of the best-planned and best-executed examples of combined-arms warfare in military history.

The Falaise Pocket

Breakthrough Becomes Breakout

Operation Cobra now entered its second phase. On August 1, the 12th Army Group, with Gen. Omar Bradley in command, became operational. The army group consisted of the newly activated Third Army under Gen. George Patton and the First Army under Gen. Courtney Hodges. General Montgomery retained command of the 21st Army Group, which consisted of the British Second Army and the Canadian First Army. With the British 21st Army Group maintaining terrific pressure on the Germans in the Bayeux-Caen area facing southward, the American 12th Army Group made the deep penetration through the Saint-Lô breakthrough and now began to swing around to envelop the entire left flank of the German 7th Army.

As the infantry moved into Coutances, CCB was ordered to leave the high ground and to double-back to Camprond. There they helped the 1st Infantry Division reduce a German strongpoint. They then headed south toward Cerisy la Salle. In the meantime, CCA came down on the left flank of CCB and bypassed the town of Montpinchon, a German strongpoint. They put a roadblock north of Montpinchon, and elements of the 2d Armored Division swung to the left and south of CCA and blocked the road south of Roncey. This cut off the retreat of a large German column consisting of fifty tanks and self-propelled guns plus infantry, artillery, and a number of horse-drawn vehicles.

The American armored commanders called for an air strike. A drove of P47s came in, bombing and strafing the entire length of the column. When the Germans tried to abandon their vehicles and run into the fields, they came under the roaring fire of the strafing planes. This, plus the tank, artillery, and automatic weapons fire from both the armored divisions, produced a horrendous debacle for this German column.

Tanks, half-tracks, and self-propelled guns littered the highway. Many were burning; others had been abandoned by the troops in a mad dash to avoid the screaming P47s. The burned bodies of German tankers climbing out of their tanks looked like charcoal mannequins. Dead German soldiers were strewn along the highway and the fields on both sides. Many horses were killed because they could not escape the traces holding them to the burning caissons. Tank dozers had to clear the road in many areas to allow our columns through.

After the air strike, CCB headed south toward its next objective, the high ground just west of Villedieu-les-Poêles. The retreating German army was at a great disadvantage. The units that had survived outside of the initial bombardment area and then were overrun during the first phase of the breakthrough broke up into smaller columns and headed south and east as rapidly as possible to escape the oncoming Allied juggernaut. With complete air superiority in daylight, the P47s ranged ahead of the columns and notified the ground troops of the Germans’ positions and movement. This enabled the armored columns, with infantry riding on the backs of the tanks, to intercept the retreating enemy columns. Nothing is more devastating to an infantry column than to be caught in the open by tanks. The tanks would fire rounds of high explosive (HE) aimed to hit the road in the middle of the column, then glance up about three feet before exploding. Where the two columns ran into each other, the armored column’s overwhelming firepower was immediately apparent. In many cases our armored columns would race ahead of the Germans, block the road in front of them, then call for an air strike. This ideal situation for an armored division demonstrated time and again the catastrophic results on the enemy of mobility, firepower, and shock action.

In addition to the 75mm and 76mm guns on the tanks, we had the awesome firepower of massed automatic weapons. Our .30-caliber machine guns, both air and water cooled, were of World War I vintage. The cyclic rate of fire, some six hundred rounds per minute, was much slower than that of the German counterpart, but they were reliable weapons and easy to maintain. Both the barrel and the bolt mechanism could be interchanged in a few minutes. The German standard .30 caliber was an MG42 of much more recent design and with a higher cyclic rate—twelve hundred rounds per minute. This was an excellent design, but the tolerances were so close that the barrel and the bolt were not interchangeable. For that reason, the German spare parts situation was much more critical than ours; in many cases it was easier for them to replace the entire gun if the barrel went bad. The Germans had no weapon comparable to our .50-caliber M1 machine gun. If this massive slug penetrated the torso, the hydraulic shock would generate a virtual explosion inside the body. If an arm or a leg was struck, the entire limb might be severed. The Germans were terrified of it.

Lightning Joe Collins, our corps commander, utilized his divisions with maximum efficiency. It was as if a chess master was maneuvering his key men in various combinations to trap the enemy pawns.

Combat Command B with elements of the 4th Infantry Division secured the high ground west of Villedieu-les-Poêles, bypassed the main city across the Sienne River, and headed south toward Saint Croix. Combat Command A with elements of the 1st Infantry Division secured Mortain, turned it over to the 1st Division, and headed southward in a wide end swing. After securing Saint Croix, CCB went to Reffuveille for a twenty-four-hour rest and maintenance period.

This was the first time that the entire combat command had been out of the line since July 8. From a maintenance point of view, the M4 Sherman’s engine was supposed to be pulled after a hundred hours of operation. Many tanks were due this hundred-hour check; the number would have been higher had medium tank losses not been so great that many tanks were brand new. In spite of easier going during the offensive, tank losses had been high whenever we encountered German tanks. The hundred-hour check is normally time-consuming, requiring six to eight hours under the best conditions in garrison. In the field with rough ground and limited wrecker facilities, it required more time.

On the afternoon of August 5, C Company of the maintenance battalion bivouacked about half a mile east of Reffuveille. Juvigny and Reffuveille, two small villages about three miles apart, had been the site of a heavy firefight two days before. Because we expected a twenty-four-hour or longer maintenance period, my driver, Vernon, bivouacked our Jeep next to a hedgerow, then chose a site for a two-man foxhole.

Even in the soft ground, the foxhole, roughly seven feet long by five feet wide by two feet deep, took us more than an hour to complete. Vernon went over to the kitchen truck and drew us a box of 10-N-1 rations, which would feed two men for five days. In addition, we had a whole box of K rations, which would last us for some time. Vernon always kept us well supplied with food.

The 10-N-1 contained two types of canned meat—Spam and corned beef. Most GIs ate more Spam than they care to remember. I suppose that’s why most GIs hated it when the war was over. The rations also contained canned green vegetables, canned fruit, crackers, coffee, toilet paper, and cigarettes. This was supplemented occasionally by a stray French chicken or some eggs, which was the next best thing to actually getting back to the headquarters company main chow line.

The next morning, just as we were packing the Jeep to move out, an MP Jeep arrived in the bivouac area with an MP officer, a driver, and a French farmer and his young daughter. The officer told Sergeant Fox that he would like to see the company commander. When Captain Oliver appeared, the MP officer told him that the French farmer’s daughter had been raped the night before by soldiers, perhaps from this company. The Frenchman’s farm was in the next field, just over the hedgerow. The mademoiselle claimed that when she had gone out to the barn to check her livestock, she’d been accosted by several American GIs. She claimed they held her down in the hay and gang-raped her.

Captain Oliver told Sergeant Fox to line up the company in formation. Seated in the Jeep, the MP captain, the driver, the farmer, and the young lady passed slowly in review in front of the men, stopping from time to time to look at individuals. She was trying to identify the men who had raped her. Everyone was extremely nervous, because rape was a serious offense in the U.S. Army and was punishable by death.

At the end of the inspection, the Jeep went back to the head of the column and the farmer and daughter had a powwow with Captain Oliver. Apparently, the mademoiselle was unable to identify her attackers, which relieved everyone. Some of the men later said that the French girl had voluntarily taken on several GIs in exchange for cigarettes and chocolate candy and had yelled rape when her father caught them.

The Battle of Mortain

The 33d Armored Regiment and its maintenance company were bivouacked nearby in Reffuveille. They had been working on the tanks; by daybreak they had removed the armor plate from the back of many tanks and placed the engines on the ground. The tank crews helped with the heavy work, then enjoyed a short but well-deserved rest while the maintenance crews took over.

I was with Maj. Dick Johnson at about 1000 when word came to cut short the maintenance effort and get the tanks back together as quickly as possible. It seemed that no sooner had the 1st Division turned over Mortain to the 30th Division than the Germans launched a massive counterattack. A 30th Division regimental combat team had been completely cut off, and CCB was to attack immediately and relieve them.

Everyone scrambled to get everything back together. Tank engines that had their maintenance check only partially completed were hurriedly reassembled and put back into the engine compartments. The armored decks were put back and bolted down. The battle-weary tank crews got back into their tanks. Although grumpy and teed off, they realized they had to rescue their fellow GIs. By noon the tanks were buttoned up and ready to go. This was an all-time record for getting an engine back in a tank and doing whatever was necessary to prepare it for battle.

A breakthrough as massive as that at Saint-Lô required a certain amount of calculated risk. Sooner or later the enemy would make a stand and counterattack. Just exactly when and where the counterattack would come, no one knew.

On August 6, the die was cast. The Germans massed their armor and motorized infantry at Mortain and attacked due west, driving toward Juvigny and Reffuveille to Avranches. The objective was to separate the First and Third Armies and cut the Third Army’s supply routes. General Bradley ordered an all-out effort to recapture and hold Mortain.

Combat Command B’s immediate objective was to relieve the isolated elements of the 30th Division. To do so required crossing an open valley between two hills and seizing the German-occupied high ground on the other side. Together with elements of the 2d Armored Division and the infantry divisions, CCB began the assault. The units were met by murderous artillery and direct tank fire from two German panzer divisions and supporting infantry. One M4 tank received a direct hit from a 155mm HE shell on the glacis plate about five inches above the bolted seam where the final drive casting (a heavy, contoured casting containing the control differential, drive axles, sprockets, and transmission) was bolted to the glacis plate. The armor was about four inches thick at the point of the radius and tapered to about two and a half inches where it bolted to the glacis plate. The bolts in this armored seam were ripped out for a span of twelve to fourteen inches, and the glacis plate was dented inward about one and a half inches. This allowed the blast to come directly into the body compartment of the tank and neutralize the crew.

Our tanks on open ground such as this were no match for the superior firepower and heavy armor protection of the German tanks. As our tank casualties began to mount, our troops called for an air strike. The Ninth Air Force was already overextended, so the Royal Air Force (RAF) was called to help.

A group of low-flying Hawker Typhoons came screaming in at low altitude, firing rockets at the German armor and infantry on top of the hill. This, combined with our heavy artillery, infantry, and tank fire, eventually brought the German counterattack to a slow, grinding halt. Combat Command B with supporting infantry finally broke through to the isolated 30th Division regiment.

The entire valley was littered with burned-out tanks and half-tracks. When we finally got our recovery vehicles into the area, the maintenance crews worked around the clock.

During this operation, the crew came upon the crashed wreck of one of the British fighters lying next to one of our tanks. It apparently had been shot down by German ground fire. The pilot had been able to crash-land the plane, but it was upside down with the tail section dug into the ground. One of the maintenance mechanics notified the sergeant that a body was hanging upside down inside, still secured by his seat belt.

There was a strong odor from the gasoline leaking from the plane’s tanks as the graves registration people removed the young British flight lieutenant’s body and put it on a stretcher. But suddenly they realized that the lieutenant was still alive. He had been hanging upside down for a number of hours; it was a miracle that he survived. A fuel line in the engine compartment had broken and fuel was leaking inside the cockpit and running down his seat, down his back, into his hair, and onto the ground. He was soaked with gasoline from head to foot and was beginning to develop red burns on his neck and hands from the high-octane fuel.

The medics brought some blankets, rolled him on his stomach, and stripped off his gasoline-soaked clothing. His entire back, buttocks, and the back of his legs were burned raw from the gasoline. As he slowly regained consciousness, he was obviously in severe pain. As soon as the medics had moved him a safe distance from the plane, he asked for a cigarette. One of the men remarked, “Damn, I knew those Limeys had guts, but this beats the hell out of anything I’ve ever seen!”

This young pilot had risked his life to help save our tankers, and our men felt deeply indebted to him, particularly because he was not an American. This type of bonding was common among Allied soldiers.

A frail, gaunt-looking member of the press corps had come over with the medics when they removed the pilot. I don’t think anyone recognized him at the time; years later when I read his book
Brave Men
, I realized that this was Ernie Pyle. He described this incident in such detail that he must have gotten his information firsthand.

While the work was going full blast on recovered tanks, we secured a list of the “W” numbers as well as the extent of damage and map coordinates on all the tanks and other vehicles that had been damaged beyond repair and left on the battlefield. We turned this list over to Division Ordnance in order to secure replacements as quickly as possible. In the meantime, the mad rush was on to repair those vehicles we had in the best and most expeditious manner. If the tank had not been set on fire completely, we could usually repair it.

When a projectile penetrated a tank, a series of incandescent particles usually showered the inside of the fighting compartment. Any crew member in the way would be killed instantly; if not, the ricochet effect inside the tank would utterly destroy him. In some cases, at close range, a projectile would strike the side of the tank and go all the way through, exiting on the other side. In this case the crew would be lucky because they would avoid the terrible ricocheting effect.

The incandescent particles would also generate many small slivers, which embed themselves in the electrical cables, causing them to short out. Often the sparks from this would set the tank on fire. There were manual fire extinguishers inside the tank and also a master lever, which the crew could pull to engulf the fighting compartment with CO

. A penetration in this compartment would often kill or severely wound several crew members, and those abandoning the tank would not have time to set off the fire extinguishers. The oil and gasoline vapors inside the tank plus the paint, seats, insulation, and other flammable materials made any fire difficult to put out once it started.

Penetration of the gas tanks or the engine would also cause fires. Once the gasoline and the ammunition went up, the tank would explode. The open cupola acted like a smoke stack, and the fire would generate such great heat it would anneal the hardness of the armor plate leaving the tank beyond repair.

If the tank struck a mine, the bottom plate would sometimes be warped to the extent that the hull could not be repaired. In this case, if the turret was not severely damaged, it could be removed and replaced on a good hull. If the turret was struck in the trunnion mount, jamming the gun elevating mechanism, it could not be repaired but could be removed and replaced with a good turret. If the tank was penetrated in the ring mount (the junction between the turret and hull), it would warp and damage the ball bearing races on the bottom of the turret and the entire tank would have to be replaced.

One of our maintenance welders found a spent projectile inside a hull. He took a carbon arc and cut the tip off, using this cone to make a plug to weld up the hole the projectile had made. After he ground the surfaces smooth on both sides and we painted the tank inside and outside, it was difficult to find the patch. I always thought this technique was one of the true ironies of warfare, that the projectile also served as the patch. It took considerable skill on the part of the welder to grind and thus camouflage these patches, because a tank crew did not like to get a replacement tank that had been penetrated, particularly if they felt there had been casualties in the tank. In spite of this, tank crews liked to get their old tank back because of sentimental attachments. After a reasonably short time, all the damaged vehicles had either been repaired or replaced, and C Company of the Maintenance Battalion headed south to join CCB near Gorron and Mayenne.
