    The American legation was divided into two parties. The first party, including Losey and Harriman, reached Sweden safely, but had lost contact with the second party. Losey volunteered to return to Norway in search of the remainder of the American legation.

    When the bombing began, he and his chauffer sought refuge in a railway tunnel with others, but once in the tunnel as he stood where he could observe the bombing, a bomb fell near the entrance to the tunnel. A fragment of it pierced Losey's heart, killing him.

    After the United States entered the war, Hollywood filmmaker Frank Capra included a brief account of Losey's death in "Divide and Conquer," the third episode of his propaganda film series, "Why We Fight," which he produced on behalf of the US Army Signal Corps.

    The 18 Apr 42 Doolittle Raid caused negligible material damage to Japan, only hitting non-military targets or missing completely but it succeeded in its goal of raising American morale and casting doubt in Japan on the ability of its military leaders to defend their home islands.

    It also caused Japan to withdraw its powerful aircraft carrier force from the Indian Ocean to defend their Home Islands, and the raid contributed to Admiral Isoroku Yamamoto's decision to attack Midway Island in the Central Pacific - an attack that turned into a decisive strategic defeat of the Imperial Japanese Navy by the US Navy in the Battle of Midway.

    After the raid, the Japanese Imperial Army conducted a massive sweep through the eastern coastal provinces of China, in an operation now known as the Zhejiang-Jiangxi Campaign, searching for the surviving American airmen and applying retribution on the Chinese who aided them, in an effort to prevent this part of China from being used again for an attack on Japan. An estimated 250,000 Chinese civilians were killed by the Japanese during this operation.

    Total raid casualties
        3 KIA: 2 off the coast of China, 1 in China;
        8 POW: 3 executed, 1 died in captivity, 4 repatriated.

    Doolittle, who initially believed that loss of all his aircraft would lead to his being court-martialled, received the Medal of Honor and was promoted two steps to Brigadier general.

    Daniel Ken "Dan" Inouye

    During the Japanese attack on Pearl Harbor in 1941, Inouye served as a medical volunteer. In 1943, when the US Army dropped its enlistment ban on Japanese Americans, he curtailed his premedical studies at the University of Hawaii and enlisted in the Army.

    Inouye volunteered to be part of the segregated all-Nisei 442nd Regimental Combat Team, an army unit made up mostly of second-generation Japanese Americans from Hawaii and the mainland. He was promoted to sergeant within his first year, and he was assigned as a platoon sergeant. He served in Italy and later in France, where he was promoted to 2nd Lieutenant for his actions.

    At one point while he was leading an attack, a shot struck him in the chest directly above his heart, but the bullet was stopped by the two silver dollars he happened to have stacked in his shirt pocket. He continued to carry the coins throughout the war in his shirt pocket as good luck charms, until he lost them shortly before the battle in which he lost his arm.

    Back in Italy, on 21 Apr 45, as Inouye led his platoon in a flanking maneuver, three German machine guns opened fire from covered positions 40 yards away, pinning his men to the ground. Inouye stood up to attack and was shot in the stomach. Ignoring his wound, he proceeded to attack and destroy the first machine gun nest with hand grenades and his Thompson submachine gun. When informed of the severity of his wound, he refused treatment and rallied his men for an attack on the second machine gun position, which he successfully destroyed before collapsing from blood loss.

    As his squad distracted the third machine gunner, Inouye crawled toward the final bunker, coming within 10 yards. As he raised himself up and cocked his arm to throw his last grenade, a German soldier inside the bunker fired a rifle grenade, which struck his right elbow, nearly severing most of his arm and leaving his primed grenade clenched in a fist that suddenly didn't belong to him anymore.

    Inouye pried the live grenade from his useless right hand and transferred it to his left and tossed the grenade into the bunker and destroyed it. He stumbled to his feet and continued forward, silencing the last German resistance with a one-handed burst from his Thompson before being wounded in the leg and tumbling unconscious to the bottom of the ridge.

    Dan Inouye recovering from his wounds

    The remainder of Inouye's mutilated right arm was later amputated at a field hospital. Although he had lost his right arm, he remained in the military until 1947 and was honorably discharged with the rank of captain.

    At the time Inouye left the Army, he was a recipient of the Bronze Star Medal and the Purple Heart. Inouye was initially awarded the Distinguished Service Cross for his bravery in this action, with the award later being upgraded to the Medal of Honor by President Bill Clinton (alongside 19 other Nisei servicemen who served in the 442nd Regimental Combat Team and were believed to have been denied proper recognition of their bravery due to their race).

    Returning to Hawaii after the war, Inouye earned a law degree and was elected to Hawaii's territorial House of Representatives in 1953, and to the territorial Senate in 1957. When Hawaii achieved statehood in 1959, he was elected as its first member of the US House of Representatives, and in 1962 he was first elected to the US Senate, going on to become one of the longest-serving US Senators in history.

    He never lost an election in 58 years as an elected official. He died at 88 on Dec 17, 2012, while still in office.
