A U.S. Army Air Force B-25B Mitchell medium bomber, one of sixteen involved in the mission, takes off from the flight deck of the USS Hornet for an air raid on the Japanese Home Islands, on April 18, 1942. The attack, later known as the Doolittle Raid, inflicted limited damage, but gave a huge boost to American morale after the attacks on Pearl Harbor months earlier. #

A U.S. Army Air Force B-25B bomber leaves the deck of the USS Hornet, for the historic raid on Tokyo under Maj. Gen. James Doolittle, on April 18, 1942. Each aircraft carried three 500-pound high-explosive bombs and one incendiary bomb. #

Above Tokyo, smoke rises from strikes on the Japanese mainland as the bombs dropped by Doolittle's raiders hit their targets on April 18, 1942. Unable to land the huge aircraft back on the USS Hornet, and running low on fuel, the bombers continued westward attempting to land in a friendly area in China. #

He is accompanied by an unidentified aide. Thirteen targets were struck, including an oil tank farm, a steel mill, and an aircraft carrier under construction. Some 50 Japanese lost their lives. #

Four unidentified Doolittle Raid crewmen, who bailed out over China from Aircraft #14, are escorted in a Chinese village before being reunited with other airmen in April of 1942. Most of the crew members made it to China, either crash landing, or bailing out over land. The assistance given by the Chinese to the airmen spurred the Japanese Imperial Army to carry out a retaliatory action called the Zhejiang-Jiangxi Campaign -- over the course of four months, entire villages were destroyed, and an estimated 250,000 Chinese civilians were killed. #

He said that "Shangri La," the mythical land identified by President Roosevelt as the place where the bombers came from, "is right here in this North American plant." #

The village of Lidice, Czechoslovakia, before it was burned the ground by the Germans in 1942. On May 27, 1942, a high-ranking Nazi official named Reinhard Heydrich was assassinated, and soon after, Adolf Hitler himself reportedly ordered that any village found harboring the assassins should be leveled, all male residents executed, females shipped off to concentration camps, and acceptable children given to German families. The village of Lidice, reportedly home to Czech resistance fighters, was chosen, and Hitler's orders were carried out starting on June 10, 1942, when all 192 men over 16 years of age were executed. #

Between 1941 and 1942, an estimated 100,000 to 150,000 Jews, Soviet prisoners, communists, gypsies, Ukrainian nationalists and civilians were executed by the Germans in Babi Yar. #

The British destroyer HMS Campbeltown sits destroyed, wedged into the dock gates of Normandie dry dock at St. Nazaire in German-occupied France, on March 28, 1942. Members of the Royal Navy and British Commandos carried out an amphibious raid on the docks earlier that day, attempting to prevent the Germans from possessing such a valuable asset. The Campbeltown was packed with with delayed-action explosives, which later detonated, killing more than 300 Germans and knocking the dock out of commission. #

Japanese soldiers stand guard over American war prisoners just before the start of the "Bataan Death March" in 1942. This photograph was stolen from the Japanese during Japan's three-year occupation. #

American and Filipino prisoners of war captured by the Japanese are shown at the start of the Death March after the surrender of Bataan on April 9, 1942, near Mariveles in the Philippines. Starting from Mariveles on April 10, some 75,000 American and Filipino prisoners of war were force-marched to Camp O'Donnell, a new prison camp 65 miles away. The prisoners, weakened after a three-month siege, were harassed by Japanese troops for days as they marched, the slow or sick killed with bayonets or swords. #

These prisoners were photographed along the Bataan Death March in April of 1942. They have their hands tied behind their backs. The estimates of the number of deaths that occurred along the march vary quite a bit, but some 5,000 to 10,000 Filipino and 600 to 650 American prisoners of war died before they could reach Camp O'Donnell. Thousands more would die in poor conditions at the camp in the following weeks. #

A Japanese aircraft carrier is bombed by a U.S. Navy plane in the Battle of the Coral Sea, in May of 1942. This was the first naval battle in history in which neither side's ships ever sighted or fired directly upon the other. #

Crewmen abandon ship on board the aircraft carrier USS Lexington, after the carrier was hit by Japanese torpedoes and bombs during the Battle of the Coral Sea. Note the destroyer alongside taking on survivors. The USS Phelps eventually torpedoed the stricken carrier, scuttling it and sending it to the bottom of the sea. #

The USS Lexington explodes after being bombed by Japanese planes in the Battle of the Coral Sea in May of 1942. More than 200 of the carrier's 2,951-man crew went down with the ship. While Japanese forces won a tactical battle, a number of their damaged ships were unable to participate in the upcoming pivotal Battle of Midway, which took place one month later. #
