GUAM, Aug. 10, 1945 (UP) - The city of Nagasaki, blasted yesterday in the war's second atomic bomb attack, was left covered with a 20,000-foot pall of smoke and dust, it was announced today, as the United States high command solemnly warned the enemy that it would continue to use the pulverizing bomb "again and again" unless the Japanese stop the war.
Photographs taken three and a half hours after the raid on Nagasaki, on the northwestern tip of Kyushu, showed scattered fires outside the smoke area, Gen. Carl Spaatz, chief of the U.S. Strategic Air Forces in the Pacific, announced.
Spaatz said no further results were available but it was almost certain that the most destructive weapon in history had scored again after Monday's initial attack which all but wiped the Honshu city of Hiroshima from the map.
As Japan reeled under its second attack by atomic bombs, each of which packs the explosive force of 20,000 tons of T.N.T., Allied planes scattered millions of leaflets over the enemy homeland warning the Jap people to "stop this useless" war and thus halt the disintegration attacks.
Some 3,000,000 leaflets were dropped by Guam-based planes, threatening to unleash the dreaded A-bomb in even greater numbers and urging Nipponese to petition Emperor Hirohito to surrender the nation.
Nagasaki, important shipping center with a population of 252,630 crammed into 12 square miles, was struck at noon yesterday. It is 200 miles southwest of Hiroshima.
Returning crewmen said that results were good and the preliminary reconnaissance pictures indicated that a good part of Nagasaki was destroyed.
Hiroshima, a city with almost 100,000 more residents than Nagasaki, was 60 per cent destroyed by the first atomic bomb.
U.S. Strategic Air Forces headquarters meanwhile announced that two fleets of Superforts continuing their relentless pounding of Japan, ripped up the Tokyo and Osaka areas in a twin-pronged assault.
Seventy B-29's dropped one-ton demolition bombs on the sprawling Tokyo arsenal area shortly before noon in the second assault on that area in 48 hours. The bombers were escorted by Iwo-based Mustang and Thunderbolt fighters.
Ninety Superforts earlier dropped demolition bombs on the Nippon oil refinery at Amagasaki in the Osaka area in a predawn attack.
All planes returned from today's twin Superfortress strike which made a total of 562 giant bombers over Japan in five missions in 48 hours, with a total of 3250 tons of bombs dropped. About 950 tons were dropped today.
Brig. Gen. Thomas F. Farrell, in charge of the atomic bomb project in the Marianas, directed the leaflet "raids." The leaflets read in part:
"To the Japanese people: America asks that you take immediate heed to what we say on this leaflet. We are in possession of the most destructive explosive ever devised by man. A single one of our newly developed atomic bombs actually is the equivalent to the explosive power of what 2,000 of our giant B-29's can carry on a single mission.
"This awful fact is one for you to ponder, and we solemnly assure you it is grimly accurate.
"We have just begun to use this weapon against your homeland. If you still have any doubt, make inquiry as to what happened at Hiroshima, when just one bomb fell on that city.
"Before using this bomb again and again to destroy every resource of the military whereby they are prolonging this useless war, we ask that you now petition the Emperor to end the war.
"Our President outlined for you 13 consequences of honorable surrender. We urge you to accept these consequences and begin work of building a new and better peace-loving Japan. You should take steps now to cease military resistance, otherwise we shall resolutely employ this bomb and all of our other superior weapons promptly and forcefully to end the war."
Throughout Thursday and early Friday, Japanese broadcasts failed to mention the Nagasaki raid. Indeed, the enemy suddenly stopped talking about the devastation at Hiroshima, where relief workers were reported attempting to identify the seared bodies of countless victims littered through the wreckage of crushed buildings.
Nagasaki lies on the southwestern coast of Kyushu, less than 200 miles from the southern tip of Korea. The 11th largest city of Japan, it has an important navy yard, shipyards, aircraft factories, steel works, aircraft plants and electric works of the Mitsubishi industries.
