There were several Native American chiefs in the Great Sioux War of 1876. Sitting Bull and Crazy horse were the two most famous of them. Crazy Horse was a Lakota Chief of the Oglala Tribe who fought several battles against the US army. His most famous war feat was serving as a decoy that lured General Custer into an ambush that ended with a victory for Native Americans. He was killed by a military guard while imprisoned in Nebraska for allegedly resisting incarceration in 1877.
Sitting Bull was a Lakota Chief of the Hunkpapa tribe who fought against the federal army for years before joining other chiefs, including Crazy Horse and inflicting a sever victory over American army men under the command of General Custer in Little Big horn. He was on the run until 1881 when he surrendered to US forces. After a period of incarceration he met Annie Oakley and joined Buffalo Bill Cody’s Wild West Show. At the time of this death he intended to join the Ghost Dance movement and was the subject of an arrest attempt that went wrong and ended up in his death by the gun of a US Indian agent in his reservation in North Dakota on December of 1890.
Well first off, both the USA and Russia were in a “race to the moon” and required a lot of infrastructure revitalization as well as a technological revolution. Both militaries used missiles and rockets as a result of this. A very important event that contributed to the US‘’s military buildup was the Cuban Missile Crisis, which forced Americans to essentially “upgrade” all artillery and intelligence programs in order to stay one step ahead of the USSR. This also contributed to technology as the world would know it for decades to come.
