Then we will look at some documents from july to see my timeline here. Then we will have another five to finish off. Even some from later into the 60s that connect to this topic. The first information that truman has about the Manhattan Project comes in april just 12 days after he becomes president on april 12. This very famous letter that some of you are very familiar with is when Henry Stimson writes to truman to tell him highly secret matter as it is mentioned in that first paragraph. He mentioned this to truman after his inauguration on april 12 after fdrs death. Just in passing, something they need to talk about in the future. Stinson sentater, this letter to truman, telling him that they need to get together quickly. You can see some interesting. Andwritten notes writes matt, tomorrow. He is telling mr. Connelly to get Henry Stenson on his cabinet for the next day. Across. Id come he did not get into much detail as he started to see the budget numbers about the project but stinson said you cant investigate that anymore. And stimsonesident tells her more about it. Truman did not know about the Manhattan Project. It takes him becoming president before he is told about the project. There had not been a successful test but the work has been going on in two or three different locations. Y started to adele developed the atomic bomb. This is the first document i wanted to share with you out of the 10 artifacts that i will share tonight. It really provides the context of when truman first finds out about the Manhattan Project and those interesting anecdotes. He did not know why he was vice president. He had come closer to it as a senator. It is about two weeks after he on sitsident where stims down and give him all of the detail. He worked in the fdr administration and is the person that is in charge of the whole operation. Here is the one he is the one that is supervising the development of drones. Stimson has come between the white house and what is going on in new mexico. He is an important, key figure in all of this. The second document we will look you can see the date at the top of the page. This is july 16, 1945. This is after the first test in new mexico of the atomic bomb. This is a sketch that was included in a 14 page report that was sent to stimson. That was related to truman. We will learn more about this in a second. Issident truman at this time at the pot stem conference in germany, meeting with stalin and initially, Winston Churchill before churchill is replaced after the british election. This 14 page report is very detailed. It is not an official report. It is actually quite casual in his writing. That is the excitement and the wonderment of the scientists and the military people involved in this First Successful test, it really comes through in the report. Last page, is on the the 14 page report. On the second page, lieutenant rose refers to the mushrooming cloud. That is the first time the Mushroom Cloud is used in that concept. They describe the explosion as being beautiful, all the different colors in the sky they say. Looking at this particular document, some of the handwritten cursive might be tricky for some of us to read but if you go closer, underneath where it says cloud drawings, it is a little faint. It does say first atomic bomb b29sion, sketches from a flying at 30,000 feet about 15 miles away. The b29s that were sent up there for observation could not get as close as they would have liked because of the weather. Dated, see the time 5 30, 5 30 eight, 5 42. 5 38, 5 42. The report goes into more detail about the level of destruction and the impact it had. Truman uses those exact words from those reports and some other documents that we will see a little bit later on. Namely, his diary entries. Colors, darkt the brown, light gray. Later on, we are able to see photographs and other footage of this atomic cloud. This is what truman receives in germany. Stis related to him by mpson. Truman is excited about the successful test. They will talk about if and when to use this against the japanese. This is the end of july. It is a fascinating document. I would encourage you to read all 14 pages. Read tight, it is easy to and it is available on the Truman Library website. It is a fascinating read. The payoff is you get this sketch on the last page. The next document is one i mentioned previously. Couple truman has a of different diary entries. I could have chosen one of three that he writes in this time. This is july 17, 1945. The day after he gets back to port. It is handwritten. It can be hard to read. Those who have done the work at the Truman Library have become familiar with trumans handwriting. This is when he is first meeting Joseph Stalin in this particular diary entry. We have other diary entries from july the 18th where he meets churchill. From july 25, he goes to a lot more detail about the atomic bomb testing. In this oneion it page of his diary. Stalin about to the different negotiations. This is very much at the beginning of the pop stem conference. M conference. Da ofs is one of trumans goals the soviets to join. He has a cryptic phrase in here. He asked them about the agenda. He told him to fire away and it is dynamite but truman says i have some dynamite too that i am not exploding now. He has this cryptic reference to dynamite. It is not too surprising that he mentions this the day after finding out about the successful test. I am just using one of the diary entries today. Thehe following day, on 18th, he says that he believes the japanese will surrender when the russians come in. Phrase on theis 18th of july entry where he says i am sure they will win manhattan appears over their homeland. Truman does not write to manhattan often in his writings. But on this door diary entry of july 18, he talks about manhattan appearing over the japanese homeland. He also goes on to say that i will inform stalin about it at an opportune time. During the pop stem conference, he tells stalin briefly but not in detail potsdam conference, he tells stalin briefly but not in detail that they have a weapon they can use against the japanese. That stalinis true did have spies in new mexico that were passing the information about the Manhattan Project back to him. Onweek later on july 25, this diary entry there, he goes into a lot more detail and talks about how the weapon is to be used against the japanese between now and august 10. Those diary entries were very expands ons truman the information he has been given by lieutenant groves. We have two contrasting documents here. One is a little misleading. We will do that one second. I am trying to keep them in chronological order. Closest you would get to the ordering of the use of the atomic bomb. This is a memo from thomas handy who is the acting chief of staff while marshall is at pop stem postsdam with truman. You can see the date on this one. It is the 25th of july. Teens are moving quickly as you can see. This, it is not super sharp but basically it has four points on the single page memo. The 509 composite group. The 20th air force will deliver its First Special bomb as soon as weather will permit. They refer to it as the special bomb without using the word atomic. It talks about the various targets and the first one there is hiroshima. The fourth one is nagasaki. The second point says that the additional bombs would be delivered on the above targets as soon they are made ready by project staff. We found out later that in the early part of august, only two bombs were ready. They used both of them. The third bomb was not probably going to be ready until around the 16th or 17th of august. Point is that the dissemination of any information about this is reserved for the secretary of war and the president. The military will not make any comments about this, in any new stories, any people asking for information, you to refer back that were for them to respond to. Point this is done with the approval of the secretary of war. It also mentions that a copy has been sent to general macarthur. This is the closest you will get to the actual orders for the dropping of the bomb on hiroshima. That is dated the 25th of july. It says after august 3 on there, it does give a date for that. At that point, theyre waiting for a response from the pop stem potsdam declaration to the japanese. This memo is from the secretary of war to truman. It is a few days later. It is the 30th of july. This one is harder to read. Some of these historic documents can be difficult to read. If you close in on this one, this is from stimson to the president. He is talking about the recent ultimatum that was made on potsdam. Also, the dramatic results of the test that we have heard already. Also, the suggestion made by the of which secretary of state burns is well aware. Is giving this is a two pager. Truman writes on the back of this memo, he says secretary of war, reply, this is the number of the memo. Suggestions are released when ready. He is talking about the atomic bomb. This is about the statement that ratherg to be released than the releasing of a bomb. Thats why the confusion. I meant to do this before. This is an interesting document. We better get the statement approved because once a bomb is dropped, we will need a statement immediately. That is why there is a little bit of a rush here. It is going backandforth in terms of what to say to the world wants this bomb is dropped. They are trying to get the suggestions approved by both the british suggestions and the suggestions from stimson himself and from truman and burns and all in the close circle of president truman at that time. That is fascinating but it should not be used here, it is more about statements rather than the bomb itself. The last one we will look at to tibet. Is a letter he takes about two weeks to get and he goes across the atlantic rather than flying. Many people argue that he did that to get ready to prepare to read the materials. He writes from the uss augusta. When he gets to germany, to potsdam, he continues to write to her. During that time, he says very little in his letters about the atomic bomb. Obviously, there is some concern are beingecy, things excepted, things of that nature. But on july 31, he makes a rather cryptic message. Then we will look at some video footage of the newsreel. Then we will look at the artifact that is the safety plug. We will finish with the video on the screen. This is the letter to bess. It was mentioned it was written july 31. Writing is not the easiest to read. It is all digitized on our website. It goes up every time i say these numbers. We have more than 1300 letters to bess. Y harry truman they are all available on our website. This is the only one that really references the atomic bomb. It is rather cryptic when he does so. If you look at the bottom of the first page on the left and the beginning of the second page on theright, he finishes bottom of this first page where he says i think mr. Stalin was stalling because he is not so happy about the english elections. He is replaced by the new climate administer. Truman says he does not know it the holee an ace in and another one is showing. Is cryptic the hole but we believe he is talking about the atomic bomb. Transcript is a little easier to read. He talks about secretary of tn byrneds. They think that stellan is stalling. Have annot know if i ace in the hole. Another one is showing. You know that truman loves his card games. That is the one time that he refers rather cryptically to the atomic bomb in his letters to his wife, bess wallace truman. Historic documents, you learn about things that are not written. The other seven or eight letters that he writes, he makes no reference to the atomic bomb. Nor in his letters to his mothers and sisters at the time. The letters at the time are rather cryptic. Moving on. We have a video clip for you. This is truman announcing the announcing the the dropping of the atomic bomb uss the uss aggressors augustus. Clip] a short time ago, an american airplane dropped one bomb on showed thend usefulness to the enemy. That bomb has more than 20,000 more power than 20,000 tons of tnt. End is not yet. With this bomb, we have added a new and revolutionary increase in destruction to supplement the growing power of our armed forces. In the present form, these bombs are now in production and even more powerful bombs are in development. T is an atomic bomb the harnessing of the basic power of the universe. It has been used against those that brought wards to the far east. We are now prepared to destroy more rapidly and completely every productive enterprise the japanese have in every city any city. We will destroy their factories and their communications. , we will be no mistake completely destroy japans power to make war. It is to spare the japanese people from utter destruction that the ultimatum will be issued at potsdam. Thatpromptly rejected ultimatum. If they do not now accept our rain fromy may expect the air that has not been seen in this earth. This will follow sea and land forces in such numbers and power as they have not yet seen. And with the fighting skills of which they are already well aware. I will talk about this one but i want to make a couple of comments about that newsreel. I think the quality is remarkable. The definition of the video is very spectacular. We are very fortunate that it is of that quality 75 years later. The second part is very compelling. You have the close of video. Truman looks at you with those eyes and you know he means business. I wonder about that when he is at the negotiating table with stalin and churchill. When he looks across the table, it looks like you have that same serious stare when he makes those tough decisions as president. It is a fascinating video. Thefact that you can see window behind him, giving you the sense of time and place as he gets ready to come home. The one thing that really comes up comes across to me is that he really means business. This next piece has been a threedimensional artifact from our museum. Tagll do a closeup of the attached. Let me talk about the object first and then the tag off to the side. All, this green, black and silver plug is the safety plug taken out of the bomb fuse from the plutonium bomb dropped on nagasaki. The green plug was removed and replaced with a red activating plug on the boxcar. Thatame of the b29 carried the ball. This is the safety plug. It was removed. If you look on the next page, you can see this more upright and other them were easy to read, the 10th of august, 1945. And a little more easy to read, the 10th of august 1945. The second one is probably a little easier to read. Name comeser whose first is here. Then he has the assistant. Those other two people that sign off on that provide to provide authenticity. I should say that this artifact and the tag will be on display in the renovated museum when we reopen the Truman Museum later this year after our renovation. This will be in a special gallery dealing with the atomic bomb. Another artifact we will show you a little later on will be in the same gallery. Artifact, we are very fortunate to have it. That is really special. The fact that Frederick Ashworth and philip bonds signed that, authenticity is really a great object. Next is its counterpart. This is from other later. We have had this on display before at the Truman Library. It will be displayed in the same gallery space as the safety plug they used to juxtapose one another. This is the paper crane made by the doctor. Waswas a japanese girl who a victim of the atomic bombs in hiroshima when she was two years old. Survive. The story is that during the , she part of her life decided to start making these paper cranes as a sign of peace. Anderent stories go back forth on whether she accomplished that. Showsre recent research that she made more than 1000 cranes before her death. This crane is rather small. It is very small. This is going to be displayed in a museum when we reopen, along with approximately five or 600 paper cranes made by students in the kansas city area. They made paper cranes to go in the exhibit alongside this original paper crane so we can help tell that story. The reason that it is also really appropriate is this is part of the peace and reconciliation efforts made by trumans grandson in the last decade or more where he is has been to japan and reached out. It was largely through his efforts that we were able to get one of the last surviving cranes donated to the librarys museum collection. All of those things have come full circle with the connection truman, clifton, daniel and the peace after 1945 and the fact that the family would allow that to be donated to the library is very special. I think when you see the renovated museum with both the safety plug and the sudoku crane sharing the same space, it will addition toaningful that episode in history. Moving on, we have one more video to show you. It might goss play, itself. Im trying to not let her do that. This is truman back in the 60s when he is asked about the atomic bomb. He never wavered much from his belief that it was the right thing to do. 1965, it was a Television Series looking at trumans decisions and the Truman Library is very fortunate that many of these outtakes this is one of those. It is quite short. He talks about the decision to drop the atomic bomb. When we issued the ultimatum to japan to surrender, the only answer we got was to go to the devil. , their peopletime seemed to be acting behind their backs, trying to salute for peace in one underhanded way or another. We knew that there was one of only two things to do. This is losing a million of our own men. There was no reaction, we the other is in terms to fight on. In this. , the effort was finally called on. An unprecedented move. He did not want his people to die more than he wanted to surrender. Still woulditary not notify us of their capitulation. We had to drop the second bomb on nagasaki. That did it, the cabinet met again and really decided that wasnt the end. They woulded us that accept an unconditional. Urrender dont you think that one military group did not speak break into the offices and try head off that record so it cannot be broadcast. They did broadcasted and they surrendered. And theyast it surrendered. If we did not drop those bombs on them to show them that we business, theyt may have never surrendered. It would have killed 3 million more people on both sides. That is why there is no question that the dropping of the atom bomb was the only sensible thing to do. It was the only thing to do. Those are my 10 artifacts. Methane we are ready for questions. I think we are ready for questions. If you have a question and you have not edited, please go ahead and do so now. Also, a questi
