They participated in war against Spain, and contributed to United States winning the war.
Explanation:
When the war with Spain really began in 1898, Roosevelt, true to his adventurous spirit, resigned to organize a volunteer regiment, later called the Rough Riders, and personally participated in the fighting in Cuba.
At the Battle of San Juan Hill, Roosevelt personally led an assault that would win the Americans victory.
For his courage he was nominated for the Medal of Honor (which he did not receive for his life for administrative and political reasons) and was awarded the status of National Hero.
