Under the leadership of Lieutenant Colonel Reinhard Gehlen, Foreign Armies East directed military espionage against the Soviet Union. It became infamous for blunders and contributed to the ultimate defeat of German invasion and occupation forces in the Soviet Union.
Where the Russians really fooled the Germans was in the lead up to Operation Bagration, which destroyed Army Group Center in June-August 1944. The Germans expected the attack against Army Group South, and had strengthened it at the expense of AG Center. The week before the Russian assault, Col. Gehlen predicted a quiet summer in AG Center’s sector. Somehow, he overlooked the incident in his memoirs.
Beyond doubt the greatest achievement of “Maskirovka” on a larger scale was to leave the German intelligence under Gehlen in ignorance that Stalin had moved 9 armies and 1 tank-corps from STAVKA-reserve to strengthen the central push in Poland. This resulted a superiority of 5-7: 1 (Glantz, 1989, 498).
In January 1945 German Intelligence represented Army Group-A in Poland as facing odds of 1:3, whereas the true proportion by January was an altogether overwhelming 1:5 (Gehlen missed the movement of armies from STAVKA reserve, underestimating the number of Russian formations concentrated in and immediately behind the 3 Vistula bridgeheads by wide margin).
Not that Soviet sources were any more accurate. OKH (Army High Command) strength reports show roughly 2.1 million German soldiers on the Eastern Front on 1 November 1944 plus about 200,000 men in Allied forces. The Soviets claim they were opposed by 3.1 million -men. On January 1945 Soviet sources cite German armor strength at 4,000 tanks and self-propelled guns. German records show about 3,500 tanks and self-propelled guns. The Soviets credit the Germans with 28,500 guns and mortars while German records show a figure of 5,700. Similar discrepancies between Soviet and German data exist throughout the war. But this another motive altogether…

German U-boat offensive conducted off the U.S. East Coast, in the Caribbean, in the Gulf of Mexico, and off Brazil.
Commander of German U-boats Vizeadmiral (vice admiral) Karl Dönitz welcomed the entry of the United States into the war in December 1941 as an opportunity to widen the U-boat offensive in the Atlantic. In planning Operation PAUKENSCHLAG (DRUMBEAT), Dönitz intended to operate against the United States and into the Caribbean larger Type IX U-boats with greater operational range. He would employ shorter-range Type VII U-boats off Newfoundland and Nova Scotia, which were much closer to his U-boat bases. Dönitz requested 12 Type IX boats from the Naval War Command for the operation but was informed on 10 December that he would have only 6. Although submarine construction had accelerated, there were still too few U-boats available. Bad weather in the Baltic had also disrupted U-boat training, and the Naval War Command insisted on maintaining a large number of U-boats in the Mediterranean to assist Axis operations in North Africa. In the end, Type IX vessel U-128 was not ready at the start of the operation, so Dönitz had less than half the force he had requested.
Operation DRUMBEAT began with only five Type IX U-boats from the Gulf of Saint Lawrence to Cape Hatteras, North Carolina. Seven Type VII U-boats went to Newfoundland and Nova Scotia. All were in place by mid-January 1942, and DRUMBEAT never involved more than a dozen German submarines at any one time. To keep the Americans off balance, a month after DRUMBEAT was launched Dönitz switched its focus to the Caribbean, where several Italian submarines joined operations.
The first victim of DRUMBEAT, the British freighter Cyclops, fell victim to U-123, a Type IX boat, on 12 January 1942. Other sinkings quickly followed. The United States was totally unprepared for the U-boat attacks. Coastal cities were ablaze with lights at night, silhouetting the merchant ships plying the coast and making them easy targets. There were also few escort vessels available, and merchant ships sailed independently in the hundreds because Chief of Naval Operations Ernest King refused to institute a convoy system, believing that an inadequately protected convoy system was worse than none. All this meant that through April 1942, German submarines sank 216 vessels aggregating 1.2 million tons in the North Atlantic, the vast majority of these in waters for which the U.S. Navy was responsible.
This so-called “second happy time” or “the American turkey shoot” for German submarines finally came to an end through a mandatory blackout of coastal U.S. cities, the instigation of convoys and antisubmarine training schools, the relocation of air assets to antisubmarine duties, and the addition of antisubmarine warships. Not only did merchant shipping losses drop off, but increasing numbers of U-boats were sunk.
On 19 July 1942, Dönitz withdrew his last two U-boats from the East Coast of the United States, relocating his submarine assets back to the mid-Atlantic and signaling an end to the campaign. American unpreparedness had come at a high price. Operation DRUMBEAT was arguably Germany’s most successful submarine operation of the entire war, resulting in the sinking of some 3 million tons of shipping. Undoubtedly, Dönitz would have enjoyed even greater success had he been able to employ more U-boats at the offset of the campaign.

British air chief marshal. Born on 23 December 1893 at Headington, Oxfordshire, William Douglas was raised in London. He attended Oxford University but left to join the Royal Field Artillery at the start of World War I. Douglas soon transferred to the Royal Flying Corps, where he qualified as a fighter pilot. By the end of the war he rose to squadron commander.
In 1919, Douglas left the military to become a test pilot with the Handley Page Aircraft Company. He was dissatisfied with civilian life and returned to the Royal Air Force (RAF) in 1920 as a squadron commander. He attended the Imperial Defense College. In 1936, Douglas was named director of staff studies at the Air Ministry; he was the only fighter pilot on the senior staff. Advanced to air vice marshal, in 1938 he became assistant chief of the air staff with responsibility for training.
Douglas was a leading critic of the tactics employed by head of Fighter Command Air Chief Marshal Hugh Dowding. On 25 November 1940, Douglas succeeded Dowding as head of Fighter Command as air marshal. Among his innovations was the Big Wing concept of large formations of fighters employed in massive sweeps. He also encouraged development of night-fighting equipment and techniques. Although his new tactics enjoyed some success, critics complained that they left much of the British homeland unprotected.
In December 1942, Douglas was promoted to air chief marshal and assigned to the Middle East Air Force (MEAF) as deputy to Air Marshal Arthur Tedder. With the reorganization of Allied air forces in April 1943, Douglas assumed command of the MEAF. During the June 1944 Allied landings in Normandy, Douglas was chief of Coastal Command and commander of British Expeditionary Air Force with the mission of securing control of the English Channel.
With the return of peace, Douglas commanded the British Air Forces of Occupation and was knighted. Promoted to marshal of the RAF, in June 1946 he followed Field Marshal Bernard Montgomery as commander of British forces in Europe and military governor of the British occupation zone in Germany.
Douglas retired from active duty in 1948 and was awarded a peerage as First Baron Douglas of Kirtleside. He assumed a seat in the House of Lords and served on the boards of the two British state airlines. After completing two autobiographies, William Sholto Douglas died in Northampton on 29 October 1969.

General Douglas MacArthur, supreme Allied commander in the Pacific, was eager to begin the campaign to retake the Philippines, which he had been forced to abandon at the beginning of the war. His forces had captured Morotai, between New Guinea and Mindanao, even as the III Marine Corps had conquered Peleliu and Angaur in the central Pacific. This put U.S. land forces in a position to begin the reconquest of the Philippines. However, after Admiral William “Bull” Halsey, in command of the Third U.S. Fleet, encountered little Japanese opposition at the Battle of Mindanao during September 9–10, 1944, MacArthur resolved to bypass the southern Philippines and make a direct assault on Leyte, in the center of the Philippine island group. Supporting the invasion was the spectacular naval Battle of Leyte Gulf.
The invasion was to be carried out by the Sixth U.S. Army under Walter Krueger with XXIV Corps (John Hodge) and X Corps (Franklin Sibert). Opposing Krueger was the Thirty-fifth Japanese Army (Suzuki Sosaku). The U.S. landings were carried out by the U.S. Seventh Fleet (Thomas Kinkaid) with air defense supplied by naval aviators as well as the Southwest Pacific Air Forces (George Kenney).
On October 17–18, army Rangers took the small islands guarding the eastern entrance to Leyte Gulf. The navy launched a two-hour bombardment on October 20, after which four infantry divisions landed on the east coast of Leyte between Tacloban and Dulag, 17 miles to the south. Two divisions of X Corps on the right and two divisions of XXIV Corps on the left fought inland from the beachheads in a four-day battle that secured operational airfields. It was November 2 before Sixth Army gained control of the Leyte Valley, from Carigara on the north coast to Abuyog in the southeast. After this, on the left, the 7th Infantry crossed the island to Baybay on the west coast.
Progress had been slow but substantial. However, torrential rains and increased resistance from consolidated Japanese forces in the mountainous interior brought the American advance to a crawl. Determined to prevent the Americans from taking the Philippines, Yamashita Tomoyuki, the Japanese commander in charge of the islands, funneled reinforcements to Leyte from surrounding islands. Between October 23 and December 11, about 45,000 Japanese troops landed at Ormoc on the island’s west coast—even though the U.S. Navy had decimated Japanese sea forces.
Recognizing the urgent necessity of stopping the Japanese buildup, General Krueger launched a two-pronged offensive into the Ormoc Valley beginning in November. On the right, X Corps, reinforced by the 32nd Infantry Division, attacked the village of Limon, which was the northern entryway into the valley. Limon did not fall until December 10. On the left, the 11th Airborne Division joined XXIV Corps, as the 7th Infantry made a thrust across the island, at Balogo, on November 22. Two weeks after this, the main assault on Ormoc got under way when the 77th Infantry landed at Ipil. Ormoc was secured by December 10, and the 77th made contact with the 7th Division. The two units now advanced up both ends of the Ormoc Valley and converged at Libungao on December 20. Six days later, on Christmas Day, Palompon, the last Japanese-held port on Leyte, fell. On December 26, the Eighth U.S. Army (Robert Eichelberger) assumed command on the island (as XXIV Corps left for the Okinawa Campaign) and spent the next four months in difficult mop-up operations.
Victory on Leyte cost the Americans 15,584 casualties, including 3,584 killed; Japanese losses totaled more than 70,000 men.

The Battle of Leyte Gulf was fought during October 23–26, 1944, in response to the attempt of Japanese naval forces to disrupt and destroy U.S. landings on the Philippine island of Leyte. The Battle of Leyte Gulf developed into the largest naval battle of any war and was also distinguished by the first kamikaze attacks.
Learning where the American landings on Leyte were to take place, Admiral Toyoda Soemu, commander in charge of the Japanese Combined Fleet, launched Operation Sho-Go (Victory), by which he intended to draw the Third U.S. Fleet (under Admiral William “Bull” Halsey) into battle north of Leyte Gulf so that the Japanese naval forces could catch the landing forces as well as the smaller Seventh U.S. Fleet (under Vice Admiral Thomas Kinkaid), which was covering the landing, in a massive double envelopment, or pincers. Whereas in previous battles, U.S. Navy commanders had enjoyed the advantage of Ultra decrypts, which gave them extensive knowledge of Japanese radio communications, the Japanese changed codes before Leyte Gulf and maintained a high degree of radio silence. Toyoda’s trap very nearly succeeded.
Toyoda assigned Vice Admiral Ozawa Jisaburo, commander in charge of the Mobile Force, tactical command of Operation Sho-Go. Ozawa divided his ships, including the two largest battleships ever built, Yamato and Masashi, five conventional battleships, and 16 cruisers, into two striking forces, under Vice Admirals Kurita Takeo and Kiyohicle Shima. Ozawa himself led a decoy fleet, including four aircraft carriers, to lure Halsey to the north while Kurita and Shima closed the pincers. A portion of Shima’s force, in company with a number of Kurita’s ships (under Vice Admiral Shejo Nishimura), were detailed to sail into the Leyte Gulf via Surigao Strait, while Kurita approached the gulf by way of the San Bernardino Strait. The rest of Shima’s force escorted Japanese troop reinforcements to Leyte Island.
On October 24, Task Force 38, under Vice Admiral Marc Mitscher, launched air strikes against Kurita as his ships crossed the Sibuyan Sea, sinking one battleship, damaging others, and prompting Kurita to reverse course for a time. Kurita’s excess of caution put him behind schedule, but Halsey overestimated the damage that had been done to him and discounted Kurita as a threat. This played into the Sho-Go plan. With Kurita apparently out of the way, Halsey pursued Ozawa’s decoy fleet.
The trap was set, but U.S. PT boats (followed by destroyers, then battleships and cruisers) attacked Nishimura as he entered Surigao Strait on the night of October 24. Nishimura was killed and all ships but a single destroyer of his force were sunk. Shima, who had been following Nishimura, withdrew without joining the fight. Thus one arm of the Japanese pincer was destroyed. Nevertheless, the other arm, Kurita’s force, was still intact; Kurita sailed into the gulf via the San Bernardino Strait on the morning of October 25. A U.S. escort carrier group under Rear Admiral Clifton Sprague sighted the force off Samar Island. Both the American and the Japanese commanders were taken by surprise, but Kurita assumed that Sprague’s ships were part of a much larger force and therefore ordered his ships to attack independently rather than risk committing his entire force. Had he used all that was available to him, he could easily have destroyed Sprague’s outnumbered, outgunned escort carriers. As it turned out, however, in independent action Sprague’s aircraft sunk two Japanese cruisers, and torpedo fire from a U.S. destroyer damaged a third cruiser. Sprague lost two of his escort carriers, one of them to a kamikaze attack. Two of his destroyers and a destroyer escort were also sunk, while a number of other ships sustained serious damage. It was perhaps the most desperate naval engagement of the Pacific war, but Kurita, presumably short on fuel—and doubtless still fearing the presence of a larger force—suddenly broke off the engagement and withdrew.
In the meantime, Admiral Kinkaid had radioed Halsey, who was in fighting pursuit of Ozawa, for aid. Halsey responded by sending one of Mitscher’s task groups south to engage Kurita. Yet he apparently did not fully realize the desperate nature of the situation in Leyte Gulf and therefore retained some ships under Rear Admiral Willis A. Lee to continue the fight against Ozawa (who had already lost four carriers to Mitscher), rather than send them south to cut off Kurita’s escape. Only after Lee was within range of what remained of Ozawa did Halsey, at last waking to the full danger to the Leyte landings and the U.S. Seventh Fleet, order Lee to break off and steam south as well. A smaller force continued to pursue Ozawa, and two more ships were sunk, but Ozawa nevertheless managed to escape complete annihilation. As for Lee, the delay imposed by Halsey meant that he arrived in the gulf too late to intercept Kurita.
The Battle of Leyte Gulf was a great American victory, albeit flawed by Halsey’s misjudgment. The Japanese lost three battleships, four aircraft carriers, 10 cruisers, and nine destroyers as well as many aircraft. Most important, the Japanese failed to disrupt the Leyte landings, thereby virtually ensuring that the Americans would retake the Philippines.

Victory on land at the Battle of Leyte, in concert with the naval victory in the Battle of Leyte Gulf, was the opening act in Douglas MacArthur’s promised return to the Philippines. These two battles allowed MacArthur to launch an amphibious invasion of Luzon, the principal island of the vast Philippine archipelago.
Preliminary to the invasion of Luzon was the landing by U.S. Eighth Army units under Robert Eichelberger on Mindoro, south of Luzon, on December 15, 1945. At San José, the infantry secured a large beachhead and immediately scratched out two airfields to accommodate air support for the Luzon operation.
On Luzon, Japanese general Yamashita Tomoyuki prepared his defenses by dividing the Fourteenth Japanese Army into three defensive groups: Shobu (140,000 men) in the north, Kembu (30,000) in the center, and Shimbu (80,000) in the south. The Japanese also unleashed a massive kamikaze campaign against the ships of the Third Fleet (under William Halsey), which furnished carrier-launched air support, and the Seventh Fleet (Thomas Kinkaid), which provided principal transport for the U.S. Sixth Army invaders under Walter Krueger. Kamikaze attacks sank 20 U.S. ships and severely damaged another 24.
Krueger landed at Lingayen Gulf on January 9, 1945—68,000 men in that first day—and immediately began a drive inland, penetrating 40 miles by January 20. I Corps, which pushed eastward, encountered the heaviest initial opposition from Yamashita’s Shobu Group. Eichelberger kept pouring in reinforcements, including the 158th Regiment, the 25th Infantry Division, and the 32nd Infantry Division. (Notably, during this titanic battle, a detachment of army Rangers staged a raid behind Japanese lines to liberate several hundred Allied prisoners at Cabanatuan.)
While I Corps and its reinforcements slugged it out with Shobu group, XIV Corps, to the right of I Corps, advanced rapidly southward across the Central Plain of Luzon. It reached Clark Field—held by the Japanese since the beginning of the war—on January 23 and, within a week, secured this major base installation while also penetrating 25 miles farther south to Calumpit.
To the right of XIV Corps, XI Corps landed at San Antonio on January 29 and squared off against Kembu group. Fighting in concert with Filipino guerrillas, the 38th and 24th Infantry divisions of XI Corps sealed off the Bataan Peninsula after Bataan and Corregidor had been liberated. On February 2, Krueger sent XIV Corps on a rapid advance to Manila, the 1st Cavalry Division reaching the outskirts of the Filipino capital on the night of February 3–4, liberating 3,500 Allied prisoners held at Santo Tomas University. On the following night, the 37th Infantry advanced into northwestern Manila and liberated another 1,300 prisoners from Bilibid Prison.
The Japanese withdrew behind the Pasig River, where they mounted a desperate resistance, holding off the U.S. advance for a month and, in the process, razing most of Manila. In this combat of attrition, 16,000 Japanese defenders died before Manila fell to U.S. forces on March 4.
During the fight for Manila, I Corps, to the north, struggled against the Shobu group defenses in rugged mountainous terrain. The 6th Infantry broke through Bongabon to the east coast on February 14, 1945, then moved to the Manila front. Baguio, the Philippine summer capital, fell on April 27, followed by Santa Fe, a major Japanese communications center, on May 27. These two cities taken, the 37th Division advanced down Cagayan Valley, by June 26 splitting the Shobu group in two, rendering both fragments incapable of mounting any significant counterattack.
In the meantime, to the south—east of Manila—XI Corps confronted the Shimbu group’s defensive line. The 6th and 43rd Infantry and the 1st Cavalry became all but stalled in the Sierra Madre, pushing back Japanese defenders by inches. Elements of XIV Corps also drove southeast toward and down the Bicol Peninsula, where resistance was not ended until June 1.
On July 1 the Eighth Army took over the campaign on Luzon, freeing up the Sixth Army for the planned invasion of Japan scheduled to begin in the fall. On July 4, General MacArthur declared Luzon secure.
