The first investigators determined the uss maine sank because of a)a bomb onboard the ship. b)spies on the ship. c)a mechanical error. d)an outside mine.

The correct answer is:

D. an outside mine.

Explanation:

The U.S.S. Maine was a battleship that had been sent to protect American lives and properties in Cuba during the revolt against the Spaniards. It exploded and sank in Havana harbor in January 1898, and was the determinant factor for the United States to intervene against the Spaniards after investigations concluded that the explosion was caused by an external cause (a mine), and that Spanish people plotted against the Americans.

disease was the number one killer of native peoples. they had had little exposure to the diseases of europe. this led to some villages being almost completely wiped out and some tribes destroyed.

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.
