Explanation:

After the victory of the attack on Fort Sumter, the General Winfield Scott wanted to wait a while before the next battle, but his own troops were anxious to attack immediately due to the rebel attacks in South Carolina.

They forced the general to think that they were ready to attack. Remarkably, they actually defeated the rebels. Winfield Scott wrote earnestly how his troops annihilated the rebels that attacked Fort Sumter.

the most famous of all the units fighting in cuba, the "rough riders" was the name given to the first u.s. volunteer cavalry under the leadership of theodore roosevelt. roosevelt resigned his position as assistant secretary of the navy in may 1898 to join the volunteer cavalry. the original plan for this unit called for filling it with men from the indian territory, new mexico, arizona, and oklahoma. however, once roosevelt joined the group, it quickly became the place for a mix of troops ranging from ivy league athletes to glee-club singers to texas rangers and indians.
