On This Date In History

On October 11, 1939, a crucial letter was delivered to President Franklin D. Roosevelt that led to the beginnings of the Manhattan Project, which would eventually produce the first atomic bombs during World War II.
In August 1939, Albert Einstein signed the letter, authored by physicist Leo Szilard, that urged Roosevelt to fund research into the possibility of using nuclear fission as a weapon.
Einstein and Szilard believed Nazi Germany was conducting similar research.
In order to alert Roosevelt to the possibility of an atomic bomb, economist Alexander Sachs met with Roosevelt to hand-deliver the letter to him on Oct. 11.
This meeting led to Roosevelt forming a committee that consisted of civilian and military representatives to study uranium. Based on the committee’s findings, the U.S. government started funding research that focused on radioactive isotope separation and nuclear chain reactions.

On October 11, 1968, Apollo 7, the first manned Apollo mission, is launched with astronauts Walter M. Schirra, Jr.; Donn F. Eisele; and Walter Cunningham aboard. Under the command of Schirra, the crew of Apollo 7 conducted an 11-day orbit of Earth, during which the crew transmitted the first live television broadcasts from orbit.

 

 

 

 

On October 11, 1954, the Viet Minh formally take over Hanoi and control of North Vietnam.
The Vietnam Doc Lap Dong Minh (Vietnam Independence League), or Viet Minh as it would become known to the world, was a Communist front organization founded by Ho Chi Minh in 1941 to organize resistance against French colonial rule and occupying Japanese forces.
With the end of the Japanese occupation in 1945, the French attempted to reimpose colonial rule. The Viet Minh launched a long and bloody guerrilla war against French colonial forces in what came to be known as the First Indochina War. Ultimately, the Viet Minh, under the leadership of General Vo Nguyen Giap, decisively defeated the French at the Battle of Dien Bien Phu in May 1954. On August 1, the armistice ending the war went into effect. The triumphant Viet Minh marched into Hanoi as the French prepared to withdraw their forces.
Under the provisions of the agreement signed at the Geneva Conference in July, Vietnam was to be temporarily split into approximately equal halves. The two halves were to be separated by a Demilitarized Zone (DMZ) running along the 17th parallel. The northern half was to be governed by the Democratic Republic of Vietnam, which had been proclaimed by Ho Chi Minh, and the southern half would be governed by the noncommunist State of Vietnam until 1956, at which time the two zones were to be reunified following internationally supervised elections. Ngo Dinh Diem, who had become premier of the State of Vietnam in June, was a Catholic and staunchly anticommunist. Diem disliked the Geneva Accords and set about to consolidate his power in the south. By the middle of 1955, Diem had effectively gained control of most of South Vietnam, and in July of that year, he declared his refusal to permit the elections called for at Geneva. This announcement led to a stepped-up insurgency in the south and ultimately to the Second Indochina War, when North Vietnamese regular units were committed in the south and U.S. forces arrived. Vietnam was not reunited until April 1975, when North Vietnamese troops captured Saigon.

On October 11, 1915, Prime Minister Vasil Radoslavov of Bulgaria issues a statement announcing his country’s entrance into the First World War on the side of the Central Powers.
Secretly courted by both sides in World War I as a potential ally in the tumultuous Balkan region, Bulgaria eventually decided in favor of the Central Powers. In his statement of October 11, 1916, Radoslavov argued that confronting the Allied powers, Britain, France and Russia, alongside Germany, Austria-Hungary and the Ottoman Empire was desirable not only for economic reasons, as the latter two countries were Bulgaria’s chief partners in trade, but also as a way for the country to defend itself against the aggression of Serbia, the Russian ally and major power in the Balkans that Radoslavov considered to be his country’s “greatest foe.”
“Today we see races that are fighting, not indeed for ideals, but solely for their material interests,” Radoslavov maintained. “The more, therefore, we are bound to a country in a material way, the greater is that country’s interest in our maintenance and increase, since thereby that one will profit who helps us and is tied to us by economic bonds… The figures show that our trade, our interests, and our economic life are inseparably linked with Turkey, Germany, and Austria-Hungary…”
Bulgaria acted quickly after its declaration of war, invading the Serbian province of Macedonia and in the process driving a wedge in front of Allied forces in Greece in their attempts to aid the Serbian army. In the summer of 1916, Bulgaria invaded and occupied a section of then-neutral Greece, mounting a major offensive in August that was only halted by British aerial and naval attacks. A stalemate ensued until 1918, when the Allies began to put more pressure on the Germans on the Western Front, forcing them to transfer a number of troops from the Salonika front, as the battlegrounds of northern Greece and Macedonia were known, where they had been aiding their Bulgarian allies. Disintegrating morale and growing discontent among the Bulgarian troops and on the home front were compounded by a new Allied offensive, launched in mid-September. On September 24, the Bulgarian government authorized its army’s commander to seek an armistice. Bulgaria formally exited World War I on September 29, 1918, having lost some 90,000 soldiers over the course of the conflict.
