You nailed it. Custer SAID it. More nonsense. Stop trying to defend this poor, arrogant excuse for an officer.
There is an element of truth in what you all say however... numbers stated really do not matter. Us Injuns were armed with repeaters, you white eyes were armed with single shot Springfield's. And anyone who seriously knows tactical ops will tell you that is the name of the game.
Further the Sioux/Cheyenne warriors uncharacteristically used a volley fire for the first couple of minutes. That is the only time in all the history of the Indian Wars that they showed that much discipline.
Nothing could have saved Custer that day except a massive infusion of troops, repeating rifles, or possibly having the Gatling guns offered to him that he supposedly refused. Even then he would have had to found some way to induce the Sioux/Cheyenne to attack him.
