MEDAL OF HONOR

VOSLER, FORREST L.

(Air Mission)

          The President of the United States takes pleasure in awarding the MEDAL of HONOR to

STAFF SERGEANT FORREST L. VOSLER,

AIR CORPS, UNITED STATES ARMY,

for service as set forth in the following

CITATION:

         “For conspicuous gallantry in action against the enemy above and beyond the call of duty while serving as a radio operator-air gunner on a heavy bombardment aircraft in a mission over Bremen, Germany, on 20 December 1943. After bombing the target, the aircraft in which T/Sgt. Vosler was serving was severely damaged by antiaircraft fire, forced out of formation, and immediately subjected to repeated vicious attacks by enemy fighters. Early in the engagement a 20-mm. cannon shell exploded in the radio compartment, painfully wounding T/Sgt. Vosler in the legs and thighs. At about the same time a direct hit on the tail of the ship seriously wounded the tail gunner and rendered the tail guns inoperative. Realizing the great need for firepower in protecting the vulnerable tail of the ship, T/Sgt. Vosler, with grim determination, kept up a steady stream of deadly fire. Shortly thereafter another 20-mm. enemy shell exploded, wounding T/Sgt. Vosler in the chest and about the face. Pieces of metal lodged in both eyes, impairing his vision to such an extent that he could only distinguish blurred shapes. Displaying remarkable tenacity and courage, he kept firing his guns and declined to take first-aid treatment. The radio equipment had been rendered inoperative during the battle, and when the pilot announced that he would have to ditch, although unable to see and working entirely by touch, T/Sgt. Vosler finally got the set operating and sent out distress signals despite several lapses into unconsciousness. When the ship ditched, T/Sgt. Vosler managed to get out on the wing by himself and hold the wounded tail gunner from slipping off until the other crewmembers could help them into the dinghy. T/Sgt. Vosler’s actions on this occasion were an inspiration to all serving with him. The extraordinary courage, coolness, and skill he displayed in the face of great odds, when handicapped by injuries that would have incapacitated the average crew member, were outstanding.”

Staff Sergeant Forrest Lee Vosler was the radio operator/top gunner aboard the Boeing B-17F-65-BO Flying Fortress 42-29664, Jersey Bounce, Jr.,¹ one of 21 B-17s of the 303rd Bombardment Group, Heavy, sent on Mission No. 90, an attack against Bremen, Germany. The bomber was under the command of 2nd Lieutenant John F. Henderson. Captain Merle R. Hungerford, an instructor pilot, acted as co-pilot. The bombers encountered heavy antiaircraft fire over the target, and were attacked by as many as 125 enemy fighters. Bombing from an altitude of  26,200 feet (7,986 meters), the B-17s dropped 24 tons of incendiary bombs.

Jersey Bounce, Jr. was hit by anti-aircraft artillery just after its bomb load was released. The number 1 engine, outboard, left wing, and the number 4 engine, outboard, right wing, were damaged. When the B-17 slowed and dropped out of its formation, it became a target of opportunity for the Luftwaffe fighters.

The crew reported that as many as ten fighters attacked, one after another. Flight engineer and top turret gunner Staff Sergeant William H. Simpkins, Jr., was credited with destroying a Focke-Wulf Fw 190 fighter, and right waist gunner Sergeant Ralph F. Burkart shot down a Messerschmitt Me 210 twin-engine heavy fighter. Sergeant Stanley E. Moody, the left waist gunner, destroyed a Messerschmitt Bf 109 and probably shot down a Messerschmitt Bf 110 twin-engine fighter.

The heavily-damaged bomber flew at low altitude as it headed for the North Sea, and then toward England. Vosler sent repeated distress signals which allowed search and rescue aircraft to locate the B-17. Lieutenant Henderson ditched 42-29644 within sight of land. The crew were quickly rescued by a small coastal freighter, MV Empire Sportsman.² The bomber crew was then transferred to a British air-sea rescue boat.

Forrest Lee Vosler was born at Lyndonville, New York, 29 July 1923. He was the son of William I. Vosler, a farmer, and Lottie I. Furness Volser. He attended Livonia Central High School, Livonia, New York, graduating in 1941. He was employed as a drill press operator by General Motors at Rochester, New York.

Forrest Lee Vosler enlisted in the Air Corps, United States Army, at Rochester, 8 October 1942. He was 6 feet, 1 inch (1.854 meters) tall and weighed 147 pounds (66.7 kilograms). After completing basic training at Atlantic City, New Jersey, Private Vosler trained as a radio operator at Scott Field, Illinois, and as an aerial gunner at Harlingen, Texas. After completing training Private Vosler was promoted to Sergeant, 25 May 1943. In August 1943, he was promoted to Staff Sergeant. Deployed to the United Kingdom, Staff Sergeant Vosler was assigned to the 358th Bombardment Squadron, Heavy, of the 303rd Bombardment Group, Heavy, at RAF Molesworth (AAF-107), Cambridgeshire, England.

Technical Sergeant Vosler was the third of only four enlisted airmen two be awarded the Medal of Honor during World War II. Vosler was hospitalized for the next 12 months. After recuperating from his wounds, Vosler was discharged from the Army Air Corps, 17 October 1944. In addition to the Medal of Honor, Forrest Vosler had been awarded the Silver Star, the Purple Heart, Air Medal, Army Good Conduct Medal, American Campaign Medal, European-African-Middle Eastern Campaign Medal with one bronze service star, World War II Victory Medal and the Presidential Unit Citation.

Following the War, Forrest Volser was employed as an engineer at radio station WSYR, the oldest continuously operating radio station in the Syracuse, New York, area. He attended the College of Business Administration, Syracuse University, at Syracuse, New York. He was a member of the Sigma Chi (ΣΧ) fraternity.

Forrest Vosler married Miss Virginia Frances Slack, 28 October 1945, at the Grace Episcopal Church, Syracuse, New York. The ceremony was presided over by Rev. James R. Rockwell. They would have a daughter, Sondra Lee Vosler, and a son, Marcellus Vosler.

Vosler had lost one eye and found that blurred vision in his remaining eye made it impossible to keep up with his studies. He dropped out of college at the end of the 1945 fall semester.

“Woody” Vosler worked for the Veterans Administration for thirty years.

Forrest Lee Vosler died at Titusville, Florida, 17 February 1992 at the age of 68 years. He was buried at Arlington National Cemetery.

The Forrest L. Vosler Noncommissioned Officer Academy and the Forrest L. Vosler Veterans Memorial Park at Peterson Air Force Base, Colorado, are named in his honor.

Boeing B-17F-65-BO Flying Fortress 42-29664, Jersey Bounce, Jr. The bomber was on its 32nd combat mission. It had been flown by at least nine different pilots and with different combat crews.

42-29664 was delivered from the Boeing plant in Seattle, Washington, to Denver, Colorado, 30 January 1943. It arrived at Salina, Kansas, 12 February 1943, and was sent on to Morrison, New Jersey, 28 February 1943. It was then flown across the north Atlantic Ocean to England. The new B-17F was assigned to the 358th Bombardment Squadron, 303rd Bombardment Group (Heavy), at RAF Molesworth, Cambridgeshire, England, 21 March 1943. It carried group identification markings VK C painted on its fuselage.

The Boeing B-17F Flying Fortress was a four-engine heavy bomber operated by a flight crew of ten. It was 74 feet, 9 inches (22.784 meters) long with a wingspan of 103 feet, 9.375 inches (31.633 meters) and an overall height of 19 feet, 1 inch (5.187 meters). Its empty weight was 34,000 pounds (15,422 kilograms), 40,437 pounds (18,342 kilograms) loaded, and the maximum takeoff weight was 56,500 pounds (25,628 kilograms).

The B-17F was powered by four air-cooled, supercharged, 1,823.129-cubic-inch-displacement (29.875 liters) Wright Cyclone C9GC (R-1820-97) nine-cylinder radial engines with turbochargers, producing 1,200 horsepower at 2,500 r.p.m. for takeoff and 1,000 horsepower at 2,300 r.p.m. at Sea Level. War Emergency Power was 1,380 horsepower. The Cyclones turned three-bladed constant-speed Hamilton-Standard Hydromatic propellers with a diameter of 11 feet, 7 inches (3.835 meters) though a 0.5625:1 gear reduction.  The R-1820-97 engine is 47.80 inches (1.214 meters) long and 55.10 inches (1.399 meters) in diameter. It weighs 1,315 pounds (596 kilograms).

These engines gave the B-17F a cruising speed of 200 miles per hour (322 kilometers per hour). The maximum speed was 299 miles per hour (481 kilometers per hour) at 25,000 feet, though with War Emergency Power, the bomber could reach 325 miles per hour (523 kilometers per hour) at 25,000 feet for short periods. The service ceiling was 37,500 feet (11,430 meters).

With a normal fuel load of 2,520 gallons (9,540 liters) the B-17F had a maximum range of 2,880 miles (4,635 kilometers). Carrying a 6,000 pound (2,722 kilogram) bomb load, the range was 1,300 miles (2,092 kilometers).

The B-17F Flying Fortress was armed with up to 13 air-cooled Browning AN-M2 .50-caliber machine guns. Power turrets mounting two guns each were located at the dorsal and ventral positions.

The maximum bomb load was 20,800 pounds over very short ranges. Normally, 4,000–6,000 pounds (1,815–2,722 kilograms) were carried. The internal bomb bay could be loaded with a maximum of eight 1,600 pound (725.75 kilogram) bombs. Two external bomb racks mounted under the wings between the fuselage and the inboard engines could carry one 4,000 pound (1,814.4 kilogram) bomb, each, though this option was rarely used.

The B-17 Flying Fortress first flew in 1935, and was was in production from 1937 to 1945. 12,731 B-17s were built by Boeing, Douglas Aircraft Company and Lockheed-Vega. (The manufacturer codes -BO, -DL and -VE follows the Block Number in each airplane’s type designation.) 3,405 of the total were B-17Fs, with 2,000 built by Boeing, 605 by Douglas and 500 by Lockheed-Vega.

Only three B-17F Flying Fortresses remain in existence.

20 December 1943: One of the most remarkable incidents in the history of warfare took place on this date.

U.S. Army Air Forces VIII Bomber Command staged Mission 159, sending 546 heavy bombers—B-17 Flying Fortresses and B-24 Liberators—from bases in Great Britain to attack the port at Bremen, Germany, 37 miles (60 kilometers) inland from the North Sea on the River Weser. This force was divided into three elements.

Ye Olde Pub was a Douglas-built B-17F-30-DL Flying Fortress, 42-3167, under the command of Second Lieutenant Charles Lester Brown, assigned to the 527th Bombardment Squadron (Heavy), 379th Bombardment Group (Heavy), of the 1st Bomb Division. It was one of 225 bombers in the first element, which targeted Bremen’s ship yards. Lieutenant Brown and his crew were flying their very first combat mission.

“Boeing B-17 Flying Fortresses of the 91st Bomb Group, 8th AF, enroute to Bremen, Germany, fly high above heavy cloud banks at 27,000 feet altitude. 20 Dec. 1943”. (NARA Ref 342-FH-3A19626-61044AC)

German defenses were very effective. In addition to massed anti-aircraft artillery (Flugabwehrkanone, or “Flak”), the Luftwaffe attacked the bomber formations with rocket-equipped, twin-engine Messerschmitt Bf 110 Zerstörer heavy fighters, as well as single-engine Messerschmitt Bf 109s and Focke-wulf Fw 190s. Only 197 bombers were effective on target, dropping 446.69 tons (405.23 metric tons) of bombs from an altitude of 27,000 feet (8,230 meters). 13 bombers did not return and 122 were damaged, 1 beyond repair. 68 American crewmen were killed, 19 wounded and 60 captured as prisoners of war. American gunners claimed 6 enemy fighters destroyed, 5 possibly destroyed, and another 6 damaged.

Ye Olde Pub was heavily damaged. Flak destroyed the plexiglas nose and damaged the number two engine (inboard, left wing) and the number four engine (outboard, right wing). The number two engine was inoperable, while the number four had to be throttled back. 42-3167 slowed and dropped out of the 527th Bomb Squadron formation.

The bomber was then attacked by many fighters and sustained further damage, which included the number three engine (inboard, right wing). Now, only the number one engine was able to maintain full power. Half of the rudder and the left horizontal stabilizer and elevator had been shot away. Internal systems were damaged. Lieutenant Brown was wounded in the left shoulder, radio operator Sergeant Richard Anthony Pechout, ball turret gunner Sergeant Samuel Wickham Blackford, and right waist gunner Sergeant Alex Yelesanko were wounded. Tail gunner Sergeant Hugh Sylvester Eckenrode was killed.

Left to right kneeling: 2nd Lieutenant Charles Lester Brown, aircraft commander; 2nd Lieutenant Spencer Gregg Luke, co-pilot; 2nd Lieutenant Albert Alexander Sadok, navigator; and 2nd Lieutenant Robert M. Andrews, bombardier. (U. S. Air Force)

With only one .50-caliber machine gun in the nose and the two in the top turret still in operation, Lieutenant Brown turned toward the attacking fighters, both to bring his three machine guns to bear, and to possibly disrupt the fighters’ aim.

With the bomber’s oxygen system damaged Brown began to lose consciousness. While reversing a steep turn, Ye Olde Pub, rolled upside down.

When Brown regained consciousness, his B-17 was in level flight at about 1,000 feet (305 meters) above the ground.

Oberleutnant Ludwig Franz Stigler, Jagdgeschwader 27 (JG 27) “Afrika,” was on the ground at Fliegerhorst Oldenburg, in Lower Saxony, having his Messerschmitt Bf 109G-6 refueled and rearmed, when he saw Ye Olde Pub flying over. Though he had already shot down two bombers that day, and his fighter had suffered a .50-caliber machine gun hit in its radiator, Oberleutnant Stigler quickly took off to intercept the B-17. He overtook and closed on the crippled bomber, which was flying south, deeper into Germany. When he saw the extensive damage, the wounded and incapacitated crewmen, he found himself unable to shoot down the enemy. He considered them no different than helpless men descending in parachutes.

Instead, he took up a position near the B-17 and signaled them to turn to the north. He then escorted the heavily damaged Flying Fortress as it continued toward the North Sea.

With hand signals, Stigler tried to get Lieutenant Brown to land the bomber so that its crew could receive medical attention. He also tried to head them toward neutral Sweden.

Once over the open sea, Stigler gave a salute, and turned back toward Germany. Ye Olde Pub headed back to England, about 250 miles (402 kilometers) away. It landed at RAF Seething (USAAF Station 146), 10 miles (16 kilometers) southeast of Norwich, Norfolk, England, and home of the 448th Bombardment Group (Heavy). After debriefing, Brown and his crew were ordered to not discuss the incident with anyone.

Likewise, Stigler, never said anything about the flight to his superiors.

In 2008, the United States Air Force completed an investigation of this incident. As a result, Second Lieutenant Brown was awarded the Air Force Cross, and the other nine members of the crew of Ye Olde Pub were each awarded the Silver Star.

B-17F-30-DL 42-3167 was built by the Douglas Aircraft Company at Long Beach, California. It was accepted by the U.S. Army Air Forces 5 March 1943, and delivered to the United Airlines Modification Center at Cheyenne Municipal Airport, Wyoming, the following day. After modifications to bring the new bomber up to current combat standards, it was flown across the United States to Dow Field at Bangor, Maine, arriving there on 15 April 1943, before being ferried across the North Atlantic Ocean to England.

On 19 April 1943, 42-3167 was assigned to the 423d Bombardment Squadron (Heavy), 306th Bombardment Group (Heavy) at RAF Thurleigh (USAAF Station 111), just north of Bedford, Bedfordshire, England, and given the unit markings of RD Z.

While attacking the submarine construction yards at Bremen, 13 June 1943, 42-3167 received extensive combat damage to the rear fuselage, vertical fin and rudder, horizontal stabilizers and rudders. It was repaired by the 306th Group Maintenance Unit.

Following repair of its combat damage, 42-3167 was transferred to the 527th Bombardment Squadron (Heavy) at RAF Kimbolton (USAAF Station 117), west of Huntington, Cambridgeshire, England. The group’s symbol, a solid white triangle with a black letter K, was painted on the vertical fin and the upper right wing, and the squadron markings, FO S, on its fuselage.

42-3167 was sent to Base Air Depot 2 at Warton Aerodrome, Lancashire, England (USAAF Station 582), for return to the United States, arriving at Homestead Field, Florida, 16 April 1944. 42-3167 was turned over to the Reconstruction Finance Corporation at Altus, Oklahoma, for storage and disposal, 11 August 1945.

Kawasaki Ki-48 Army Type 99 twin-engine light bomber. Allied reporting name, “Lily.”

20 December 1941: For the first time, the 1st American Volunteer Group (the “Flying Tigers”) engaged aircraft of the Empire of Japan in combat. 1st and 2nd Squadrons, based at Kunming, China, intercepted ten Kawasaki Ki-48-I Army Type 99 twin-engine light bombers of the 82nd Dokuritsu Hiko Chutai.

Japan and China had been at war since 1937. The Japanese aircraft were based at the Gia Lâm airport, near Hà Nội in occupied French Indochina. They had frequently attacked Kunming, a Chinese city at the northern end of the Burma Road, and had previously been unopposed. For this mission, the bomber squadron initially had a fighter escort, but the fighters turned back at the Indo-China/China border.

The AVG had established a network of observers which would report enemy aircraft in time for the fighters to take off to intercept them. Having received the warning of inbound aircraft, the 1st and 2nd AVG squadrons were ordered into battle.

Sources vary widely as to the number of AVG aircraft involved, but there may have been as many as 16 Curtiss-Wright Hawk 81-A3s from the 1st Squadron, and 8 more from the 2nd Squadron. There is a general consensus that the fighters shot down three of the Japanese bombers, and that a fourth went down while returning to base. Other sources say that only one of the ten Ki-48s made it back to its base. AVG pilots claimed five bombers shot down and two damaged. One Hawk 81 ran out fuel and was damaged beyond repair in a forced landing.

An RAF order for 100 Tomahawk IIb (Curtiss-Wright Hawk 81-A2 ) was released to be available for AVG. They were built as hybrids of the Tomahawk Mk.IIb and the P-40C Warhawk, though the airplanes intended for the AVG differed in details from either the standard Britsih or American fighters. The airplanes were painted in the standard RAF brown and green camouflage patterns. The completed airplanes were knocked down, crated, then shipped from New York. They were reassembled at a CAMCO facility near Rangoon, Burma.

The Curtiss-Wright Corporation Hawk 81 was a single-seat, single-engine pursuit (fighter). It was a low-wing monoplane of all-metal construction and used flush riveting to reduce aerodynamic drag. It had an enclosed cockpit and retractable landing gear. Extensive wind tunnel testing at the NACA Langley laboratories refined the airplane’s design, significantly increasing the top speed.

The Hawk 81 was 31 feet, 8¾ inches (9.671 meters) long, with a wingspan of 37 feet, 4 inches (11.379 meters) and overall height of 10 feet, 7 inches (3.226 meters).

The Tomahawk/Warhawk was powered by a liquid-cooled, supercharged, 1,710.597ubic-inch-displacement (28.032 liter) Allison Engineering Co. V-1710-C15 (V-1710-33), a single overhead cam (SOHC) 60° V-12 engine, which had a Continuous Power Rating of 930 horsepower at 2,600 r.p.m., from Sea Level to 12,800 feet (3,901 meters), and 1,150 horsepower at 3,000 r.p.m. to 14,300 feet (4,359 meters) for Take Off and Military Power. The engine drove a three-bladed Curtiss Electric constant-speed propeller through a 2:1 gear reduction. The V-1710-33 was 8 feet, 2.54 inches (2.503 meters) long, 3 feet, 5.88 inches (1.064 meters) high, and 2 feet, 5.29 inches (0.744 meters) wide. It weighed 1,340 pounds (607.8 kilograms).

Armament consisted of two air-cooled Browning AN-M2 .50-caliber machine guns mounted in the cowling and synchronized to fire forward through the propeller arc, with 380 rounds of ammunition per gun. In British service, the Tomahawk was armed with an additional four Browning .303 Mark II machine guns, with two in each wing. The American P-40, P-40B and P-40C Warhawks had two or four Browning AN-M2 .30-caliber aircraft machine guns as wing-mounted guns.

The “blood chit” was sometimes sewn on AVG pilots’ jackets.

The AVG pilots were employees of the Central Aircraft Manufacturing Company (CAMCO). Most were former United States military pilots who had been secretly recruited. They were required to resign their officers’ commissions. Importantly, they were all civilians—not members of the Chinese military–nor were they otherwise employed by the government of China. They each had a one year contract, 4 July 1941–4 July 1942. They were paid a monthly salary, more than three times their former military pay, and were also paid a bonus for each enemy airplane they shot down.

“This photograph of the Clipper, aloft at the mouth of the Middle River, was taken from another plane by Robert F. Kniesche, Sun staff photographer.” (The Sun (Baltimore), Vol. 196–D, Friday 21 December 1934, Page 30, Columns 3–5 )

20 December 1934: William K. (“Ken”) Ebel lifted off from Middle River, Maryland, taking the Martin M-130 “Clipper” for its first flight. The M-130 was airborne for approximately 1 hours. Flying at 1,200 feet (366 meters), it reached 160 miles per hour (257 kilometers per hour).

Three-view illustration of the Martin M-130. (Flight, The Aircraft Engineer & Airships, Vol. XXVII, No. 1361, 24 January 1935, Page 99)

NC14716, named China Clipper, was the first of three Martin M-130 four-engine flying boats built for Pan American Airways. It was used to inaugurate the first commercial transpacific air service from San Francisco to Manila in November, 1935. Built at a cost of $417,000 by the Glenn L. Martin Company in Baltimore, Maryland, it was delivered to Pan Am on October 9, 1935.

The airplane was operated by a flight crew of 6 to 9, depending on the length of the flight, plus cabin staff, and could carry 18 passengers on overnight flights or a maximum 36 passengers.
