O'BRIEN, WILLIAM J.
Rank and organization: Lieutenant Colonel, U.S. Army, 1st Battalion, 105th Infantry, 27th Infantry Division. Place and date: At Saipan, Marianas Islands, 20 June through 7 July 1944. Entered service at: Troy, N.Y. Birth: Troy, N.Y. G.O. No.: 35, 9 May 1945.
Citation: For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty at Saipan, Marianas Islands, from 20 June through 7 July 1944. When assault elements of his platoon were held up by intense enemy fire, Lt. Col. O'Brien ordered 3 tanks to precede the assault companies in an attempt to knock out the strongpoint. Due to direct enemy fire the tanks' turrets were closed, causing the tanks to lose direction and to fire into our own troops. Lt. Col. O'Brien, with complete disregard for his own safety, dashed into full view of the enemy and ran to the leader's tank, and pounded on the tank with his pistol butt to attract 2 of the tank's crew and, mounting the tank fully exposed to enemy fire, Lt. Col. O'Brien personally directed the assault until the enemy strongpoint had been liquidated. On 28 June 1944, while his platoon was attempting to take a bitterly defended high ridge in the vicinity of Donnay, Lt. Col. O'Brien arranged to capture the ridge by a double envelopment movement of 2 large combat battalions. He personally took control of the maneuver. Lt. Col. O'Brien crossed 1,200 yards of sniper-infested underbrush alone to arrive at a point where 1 of his platoons was being held up by the enemy. Leaving some men to contain the enemy he personally led 4 men into a narrow ravine behind, and killed or drove off all the Japanese manning that strongpoint. In this action he captured S machineguns and one 77-mm. fieldpiece. Lt. Col. O'Brien then organized the 2 platoons for night defense and against repeated counterattacks directed them. Meanwhile he managed to hold ground. On 7 July 1944 his battalion and another battalion were attacked by an overwhelming enemy force estimated at between 3,000 and 5,000 Japanese. With bloody hand-to-hand fighting in progress everywhere, their forward positions were finally overrun by the sheer weight of the enemy numbers. With many casualties and ammunition running low, Lt. Col. O'Brien refused to leave the front lines. Striding up and down the lines, he fired at the enemy with a pistol in each hand and his presence there bolstered the spirits of the men, encouraged them in their fight and sustained them in their heroic stand. Even after he was seriously wounded, Lt. Col. O'Brien refused to be evacuated and after his pistol ammunition was exhausted, he manned a .50 caliber machinegun, mounted on a jeep, and continued firing. When last seen alive he was standing upright firing into the Jap hordes that were then enveloping him. Some time later his body was found surrounded by enemy he had killed His valor was consistent with the highest traditions of the service.

O'CALLAHAN, JOSEPH TIMOTHY
Rank and organization: Commander (Chaplain Corps), U.S. Naval Reserve, U.S.S. Franklin. Place and date: Near Kobe, Japan, 19 March 1945. Entered service at: Massachusetts. Born: 14 May 1904, Boston, Mass.
Citation: For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving as chaplain on board the U.S.S. Franklin when that vessel was fiercely attacked by enemy Japanese aircraft during offensive operations near Kobe, Japan, on 19 March 1945. A valiant and forceful leader, calmly braving the perilous barriers of flame and twisted metal to aid his men and his ship, Lt. Comdr. O'Callahan groped his way through smoke-filled corridors to the open flight deck and into the midst of violently exploding bombs, shells, rockets, and other armament. With the ship rocked by incessant explosions, with debris and fragments raining down and fires raging in ever-increasing fury, he ministered to the wounded and dying, comforting and encouraging men of all faiths; he organized and led firefighting crews into the blazing inferno on the flight deck; he directed the jettisoning of live ammunition and the flooding of the magazine; he manned a hose to cool hot, armed bombs rolling dangerously on the listing deck, continuing his efforts, despite searing, suffocating smoke which forced men to fall back gasping and imperiled others who replaced them. Serving with courage, fortitude, and deep spiritual strength, Lt. Comdr. O'Callahan inspired the gallant officers and men of the Franklin to fight heroically and with profound faith in the face of almost certain death and to return their stricken ship to port.

OGDEN, CARLOS C.
Rank and organization: First Lieutenant, U.S. Army, Company K, 314th Infantry, 79th Infantry Division. Place and date: Near Fort du Roule, France, 25 June 1944. Entered service at: Fairmont, Ill. Born: 19 May 1917, Borton, Ill. G.O. No.: 49, 28 June 1945.
Citation: On the morning of 25 June 1944, near Fort du Roule, guarding the approaches to Cherbourg, France, 1st Lt. Ogden's company was pinned down by fire from a German 88-mm. gun and 2 machineguns. Arming himself with an M-1 rifle, a grenade launcher, and a number of rifle and handgrenades, he left his company in position and advanced alone, under fire, up the slope toward the enemy emplacements. Struck on the head and knocked down by a glancing machinegun bullet, 1st Lt. Ogden, in spite of his painful wound and enemy fire from close range, continued up the hill. Reaching a vantage point, he silenced the 88mm. gun with a well-placed rifle grenade and then, with handgrenades, knocked out the 2 machineguns, again being painfully wounded. 1st Lt. Ogden's heroic leadership and indomitable courage in alone silencing these enemy weapons inspired his men to greater effort and cleared the way for the company to continue the advance and reach its objectives.

O'HARE, EDWARD HENRY
Rank and organization: Lieutenant, U.S. Navy. Born: 13 March 1914, St. Louis, Mo. Entered service at: St. Louis, Mo. Other Navy awards: Navy Cross, Distinguished Flying Cross with 1 gold star.
Citation: For conspicuous gallantry and intrepidity in aerial combat, at grave risk of his life above and beyond the call of duty, as section leader and pilot of Fighting Squadron 3 on 20 February 1942. Having lost the assistance of his teammates, Lt. O'Hare interposed his plane between his ship and an advancing enemy formation of 9 attacking twin-engine heavy bombers. Without hesitation, alone and unaided, he repeatedly attacked this enemy formation, at close range in the face of intense combined machinegun and cannon fire. Despite this concentrated opposition, Lt. O'Hare, by his gallant and courageous action, his extremely skillful marksmanship in making the most of every shot of his limited amount of ammunition, shot down 5 enemy bombers and severely damaged a sixth before they reached the bomb release point. As a result of his gallant action--one of the most daring, if not the most daring, single action in the history of combat aviation--he undoubtedly saved his carrier from serious damage.

OHATA, ALLAN M.
Citation: Sergeant Allan M. Ohata distinguished himself by extraordinary heroism in action on 29 and 30 November 1943, near Cerasuolo, Italy. Sergeant Ohata, his squad leader, and three men were ordered to protect his platoon’s left flank against an attacking enemy force of 40 men, armed with machine guns, machine pistols, and rifles. He posted one of his men, an automatic rifleman, on the extreme left, 15 yards from his own position. Taking his position, Sergeant Ohata delivered effective fire against the advancing enemy. The man to his left called for assistance when his automatic rifle was shot and damaged. With utter disregard for his personal safety, Sergeant Ohata left his position and advanced 15 yards through heavy machine gun fire. Reaching his comrade’s position, he immediately fired upon the enemy, killing 10 enemy soldiers and successfully covering his comrade’s withdrawal to replace his damaged weapon. Sergeant Ohata and the automatic rifleman held their position and killed 37 enemy soldiers. Both men then charged the three remaining soldiers and captured them. Later, Sergeant Ohata and the automatic rifleman stopped another attacking force of 14, killing four and wounding three while the others fled. The following day he and the automatic rifleman held their flank with grim determination and staved off all attacks. Staff Sergeant Ohata’s extraordinary heroism and devotion to duty are in keeping with the highest traditions of military service and reflect great credit on him, his unit, and the United States Army.

O'KANE, RICHARD HETHERINGTON
Rank and organization: Commander, U.S. Navy, commanding U.S.S. Tang. Place and date: Vicinity Philippine Islands, 23 and 24 October 1944. Entered service at: New Hampshire. Born: 2 February 1911, Dover, N.H.
Citation: For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty as commanding officer of the U.S.S. Tang operating against 2 enemy Japanese convoys on 23 and 24 October 1944, during her fifth and last war patrol. Boldly maneuvering on the surface into the midst of a heavily escorted convoy, Comdr. O'Kane stood in the fusillade of bullets and shells from all directions to launch smashing hits on 3 tankers, coolly swung his ship to fire at a freighter and, in a split-second decision, shot out of the path of an onrushing transport, missing it by inches. Boxed in by blazing tankers, a freighter, transport, and several destroyers, he blasted 2 of the targets with his remaining torpedoes and, with pyrotechnics bursting on all sides, cleared the area. Twenty-four hours later, he again made contact with a heavily escorted convoy steaming to support the Leyte campaign with reinforcements and supplies and with crated planes piled high on each unit. In defiance of the enemy's relentless fire, he closed the concentration of ship and in quick succession sent 2 torpedoes each into the first and second transports and an adjacent tanker, finding his mark with each torpedo in a series of violent explosions at less than l,000-yard range. With ships bearing down from all sides, he charged the enemy at high speed, exploding the tanker in a burst of flame, smashing the transport dead in the water, and blasting the destroyer with a mighty roar which rocked the Tang from stem to stern. Expending his last 2 torpedoes into the remnants of a once powerful convoy before his own ship went down, Comdr. O'Kane, aided by his gallant command, achieved an illustrious record of heroism in combat, enhancing the finest traditions of the U.S. Naval Service.

OKUBO, JAMES K.
Citation: Technician Fifth Grade James K. Okubo distinguished himself by extraordinary heroism in action on 28 and 29 October and 4 November 1944, in the Foret Domaniale de Champ, near Biffontaine, eastern France. On 28 October, under strong enemy fire coming from behind mine fields and roadblocks, Technician Fifth Grade Okubo, a medic, crawled 150 yards to within 40 yards of the enemy lines. Two grenades were thrown at him while he left his last covered position to carry back wounded comrades. Under constant barrages of enemy small arms and machine gun fire, he treated 17 men on 28 October and 8 more men on 29 October. On 4 November, Technician Fifth Grade Okubo ran 75 yards under grazing machine gun fire and, while exposed to hostile fire directed at him, evacuated and treated a seriously wounded crewman from a burning tank, who otherwise would have died. Technician Fifth Grade James K. Okubo’s extraordinary heroism and devotion to duty are in keeping with the highest traditions of military service and reflect great credit on him, his unit, and the United States Army.

OKUTSU, YUKIO
Citation: Technical Sergeant Yukio Okutsu distinguished himself by extraordinary heroism in action on 7 April 1945, on Mount Belvedere, Italy. While his platoon was halted by the crossfire of three machine guns, Technical Sergeant Okutsu boldly crawled to within 30 yards of the nearest enemy emplacement through heavy fire. He destroyed the position with two accurately placed hand grenades, killing three machine gunners. Crawling and dashing from cover to cover, he threw another grenade, silencing a second machine gun, wounding two enemy soldiers, and forcing two others to surrender. Seeing a third machine gun, which obstructed his platoon’s advance, he moved forward through heavy small arms fire and was stunned momentarily by rifle fire, which glanced off his helmet. Recovering, he bravely charged several enemy riflemen with his submachine gun, forcing them to withdraw from their positions. Then, rushing the machine gun nest, he captured the weapon and its entire crew of four. By these single-handed actions he enabled his platoon to resume its assault on a vital objective. The courageous performance of Technical Sergeant Okutsu against formidable odds was an inspiration to all. Technical Sergeant Okutsu’s extraordinary heroism and devotion to duty are in keeping with the highest traditions of military service and reflect great credit on him, his unit, and the United States Army.

OLSON, ARLO L.
Rank and organization: Captain, U.S. Army, 1 5th Infantry, 3d Infantry Division. Place and date: Crossing of the Volturno River, Italy, 13 October 1943. Entered service at: Toronto, S. Dak. Birth: Greenville, Iowa. G.O. No.: 71, 31 August 1944.
Citation: For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty. On 13 October 1943, when the drive across the Volturno River began, Capt. Olson and his company spearheaded the advance of the regiment through 30 miles of mountainous enemy territory in 13 days. Placing himself at the head of his men, Capt. Olson waded into the chest-deep water of the raging Volturno River and despite pointblank machine-gun fire aimed directly at him made his way to the opposite bank and threw 2 handgrenades into the gun position, killing the crew. When an enemy machinegun 150 yards distant opened fire on his company, Capt. Olson advanced upon the position in a slow, deliberate walk. Although 5 German soldiers threw handgrenades at him from a range of 5 yards, Capt. Olson dispatched them all, picked up a machine pistol and continued toward the enemy. Advancing to within 15 yards of the position he shot it out with the foe, killing 9 and seizing the post. Throughout the next 13 days Capt. Olson led combat patrols, acted as company No. 1 scout and maintained unbroken contact with the enemy. On 27 October 1943, Capt. Olson conducted a platoon in attack on a strongpoint, crawling to within 25 yards of the enemy and then charging the position. Despite continuous machinegun fire which barely missed him, Capt. Olson made his way to the gun and killed the crew with his pistol. When the men saw their leader make this desperate attack they followed him and overran the position. Continuing the advance, Capt. Olson led his company to the next objective at the summit of Monte San Nicola. Although the company to his right was forced to take cover from the furious automatic and small arms fire, which was directed upon him and his men with equal intensity, Capt. Olson waved his company into a skirmish line and despite the fire of a machinegun which singled him out as its sole target led the assault which drove the enemy away. While making a reconnaissance for defensive positions, Capt. Olson was fatally wounded. Ignoring his severe pain, this intrepid officer completed his reconnaissance, Supervised the location of his men in the best defense positions, refused medical aid until all of his men had been cared for, and died as he was being carried down the mountain.

OLSON, TRUMAN O.
Rank and organization: Sergeant, U.S. Army, Company B, 7th Infantry, 3d Infantry Division. Place and date: Near Cisterna di Littoria, Italy, 30-31 January 1944. Entered service at: Cambridge, Wis. Birth: Christiana, Wis. G.O. No.: 6, 24 January 1945.
Citation: For conspicuous gallantry and intrepidity above and beyond the call of duty. Sgt. Olson, a light machine gunner, elected to sacrifice his life to save his company from annihilation. On the night of 30 January 1944, after a 16-hour assault on entrenched enemy positions in the course of which over one-third of Company B became casualties, the survivors dug in behind a horseshoe elevation, placing Sgt. Olson and his crew, with the 1 available machinegun, forward of their lines and in an exposed position to bear the brunt of the expected German counterattack. Although he had been fighting without respite, Sgt. Olson stuck grimly to his post all night while his guncrew was cut down, 1 by 1, by accurate and overwhelming enemy fire. Weary from over 24 hours of continuous battle and suffering from an arm wound, received during the night engagement, Sgt. Olson manned his gun alone, meeting the full force of an all-out enemy assault by approximately 200 men supported by mortar and machinegun fire which the Germans launched at daybreak on the morning of 31 January. After 30 minutes of fighting, Sgt. Olson was mortally wounded, yet, knowing that only his weapons stood between his company and complete destruction, he refused evacuation. For an hour and a half after receiving his second and fatal wound he continued to fire his machinegun, killing at least 20 of the enemy, wounding many more, and forcing the assaulting German elements to withdraw.

ONO, FRANK H.
Citation: Private First Class Frank H. Ono distinguished himself by extraordinary heroism in action on 4 July 1944, near Castellina, Italy. In attacking a heavily defended hill, Private First Class Ono’s squad was caught in a hail of formidable fire from the well-entrenched enemy. Private First Class Ono opened fire with his automatic rifle and silenced one machine gun 300 hundred yards to the right front. Advancing through incessant fire, he killed a sniper with another burst of fire, and while his squad leader reorganized the rest of the platoon in the rear, he alone defended the critical position. His weapon was then wrenched from his grasp by a burst of enemy machine pistol fire as enemy troops attempted to close in on him. Hurling hand grenades, Private First Class Ono forced the enemy to abandon the attempt, resolutely defending the newly won ground until the rest of the platoon moved forward. Taking a wounded comrade's rifle, Private First Class Ono again joined in the assault. After killing two more enemy soldiers, he boldly ran through withering automatic, small arms, and mortar fire to render first aid to his platoon leader and a seriously wounded rifleman. In danger of being encircled, the platoon was ordered to withdraw. Volunteering to cover the platoon, Private First Class Ono occupied virtually unprotected positions near the crest of the hill, engaging an enemy machine gun emplaced on an adjoining ridge and exchanging fire with snipers armed with machine pistols. Completely disregarding his own safety, he made himself the constant target of concentrated enemy fire until the platoon reached the comparative safety of a draw. He then descended the hill in stages, firing his rifle, until he rejoined the platoon. Private First Class Ono’s extraordinary heroism and devotion to duty are in keeping with the highest traditions of military service and reflect great credit on him, his unit, and the United States Army.

ORESKO, NICHOLAS
Rank and organization: Master Sergeant, U.S. Army, Company C, 302d Infantry, 94th Infantry Division. Place and date: Near Tettington, Germany, 23 January 1945. Entered service at: Bayonne, N.J. Birth: Bayonne, N.J. G.O. No.: 95, 30 October 1945.
Citation: M/Sgt. Oresko was a platoon leader with Company C, in an attack against strong enemy positions. Deadly automatic fire from the flanks pinned down his unit. Realizing that a machinegun in a nearby bunker must be eliminated, he swiftly worked ahead alone, braving bullets which struck about him, until close enough to throw a grenade into the German position. He rushed the bunker and, with pointblank rifle fire, killed all the hostile occupants who survived the grenade blast. Another machinegun opened up on him, knocking him down and seriously wounding him in the hip. Refusing to withdraw from the battle, he placed himself at the head of his platoon to continue the assault. As withering machinegun and rifle fire swept the area, he struck out alone in advance of his men to a second bunker. With a grenade, he crippled the dug-in machinegun defending this position and then wiped out the troops manning it with his rifle, completing his second self-imposed, 1-man attack. Although weak from loss of blood, he refused to be evacuated until assured the mission was successfully accomplished. Through quick thinking, indomitable courage, and unswerving devotion to the attack in the face of bitter resistance and while wounded, M /Sgt. Oresko killed 12 Germans, prevented a delay in the assault, and made it possible for Company C to obtain its objective with minimum casualties.

OTANI, KAZUO
Citation: Staff Sergeant Kazuo Otani distinguished himself by extraordinary heroism in action on 15 July 1944, near Pieve Di S. Luce, Italy. Advancing to attack a hill objective, Staff Sergeant Otani’s platoon became pinned down in a wheat field by concentrated fire from enemy machine gun and sniper positions. Realizing the danger confronting his platoon, Staff Sergeant Otani left his cover and shot and killed a sniper who was firing with deadly effect upon the platoon. Followed by a steady stream of machine gun bullets, Staff Sergeant Otani then dashed across the open wheat field toward the foot of a cliff, and directed his men to crawl to the cover of the cliff. When the movement of the platoon drew heavy enemy fire, he dashed along the cliff toward the left flank, exposing himself to enemy fire. By attracting the attention of the enemy, he enabled the men closest to the cliff to reach cover. Organizing these men to guard against possible enemy counterattack, Staff Sergeant Otani again made his way across the open field, shouting instructions to the stranded men while continuing to draw enemy fire. Reaching the rear of the platoon position, he took partial cover in a shallow ditch and directed covering fire for the men who had begun to move forward. At this point, one of his men became seriously wounded. Ordering his men to remain under cover, Staff Sergeant Otani crawled to the wounded soldier who was lying on open ground in full view of the enemy. Dragging the wounded soldier to a shallow ditch, Staff Sergeant Otani proceeded to render first aid treatment, but was mortally wounded by machine gun fire. Staff Sergeant Otani’s extraordinary heroism and devotion to duty are in keeping with the highest traditions of military service and reflect great credit on him, his unit, and the United States Army.

OWENS, ROBERT ALLEN
Rank and organization: Sergeant, U.S. Marine Corps. Born: 13 September 1920, Greenville, S.C. Accredited to: South Carolina.
Citation: For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving with a marine division, in action against enemy Japanese forces during extremely hazardous landing operations at Cape Torokina, Bougainville, Solomon Islands, on 1 November 1943. Forced to pass within disastrous range of a strongly protected, well-camouflaged Japanese 75-mm. regimental gun strategically located on the beach, our landing units were suffering heavy losses in casualties and boats while attempting to approach the beach, and the success of the operations was seriously threatened. Observing the ineffectiveness of marine rifle and grenade attacks against the incessant, devastating fire of the enemy weapon and aware of the urgent need for prompt action, Sgt. Owens unhesitatingly determined to charge the gun bunker from the front and, calling on 4 of his comrades to assist him, carefully placed them to cover the fire of the 2 adjacent hostile bunkers. Choosing a moment that provided a fair opportunity for passing these bunkers, he immediately charged into the mouth of the steadily firing cannon and entered the emplacement through the fire port, driving the guncrew out of the rear door and insuring their destruction before he himself was wounded. Indomitable and aggressive in the face of almost certain death, Sgt. Owens silenced a powerful gun which was of inestimable value to the Japanese defense and, by his brilliant initiative and heroic spirit of self-sacrifice, contributed immeasurably to the success of the vital landing operations. His valiant conduct throughout reflects the highest credit upon himself and the U.S. Naval Service.

OZBOURN, JOSEPH WILLIAM
Rank and organization: Private, U.S. Marine Corps. Born: 24 October 1919, Herrin, Ill. Accredited to: Illinois.
Citation: For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty as a Browning Automatic Rifleman serving with the 1st Battalion, 23d Marines, 4th Marine Division, during the battle for enemy Japanese-held Tinian Island, Marianas Islands, 30 July 1944. As a member of a platoon assigned the mission of clearing the remaining Japanese troops from dugouts and pillboxes along a tree line, Pvt. Ozbourn, flanked by 2 men on either side, was moving forward to throw an armed handgrenade into a dugout when a terrific blast from the entrance severely wounded the 4 men and himself. Unable to throw the grenade into the dugout and with no place to hurl it without endangering the other men, Pvt. Ozbourn unhesitatingly grasped it close to his body and fell upon it, sacrificing his own life to absorb the full impact of the explosion, but saving his comrades. His great personal valor and unwavering loyalty reflect the highest credit upon Pvt. Ozbourn and the U.S. Naval Service. He gallantly gave his life for his country.
