The troops hadn't been trained - as the army commander knew.
The Union had not yet built-up an effective cavalry.
Some of the enemy were wearing blue uniforms, which confused them.

Poor communication, green, untrained troops.
They didn't know the terrain as well.
There were a number of problems facing Union General John Pope as the Second Battle of Bull Run was soon to begin. One problem was the fact that the Confederate forces were far more mobile. For example, Stonewall Jackson's infantry was able to march 120 miles in two days. Also, Pope could not match the quality of the Southern cavalry. The knowledge of the terrain was also against Pope. The Rebels knew more about the landscape then did Pope.

Whatever problems arise in our life, we sould be ready to face the bull by horns
Union forces were defeated at the First Battle of Bull Run, also known as the First Manassas, on July 21, 1861, primarily due to underestimating the Confederate army and overconfidence in their own capabilities. The battle revealed significant shortcomings in Union leadership and coordination, as well as the effective tactics employed by Confederate generals like Thomas "Stonewall" Jackson. The Union's retreat highlighted the challenges they would face in the prolonged conflict ahead and dispelled any illusions of a quick victory in the Civil War.

To be quite frankly, they didn't have any problems. The Soviets were trained to deal with the harsh weater conditions they experianced and had a good logistical support sstem of food, ammo and tanks.
They ran out if ammo
White Bull of the Miniconjous, Rain-in-the-Face, Flat Lip and Brave Bear killed General Custer and his men. So I would say the Indians won or the Union Army was defeated that day.
A large Union force in a superior defensive position…
