D. Secession of First Southern States ~ Dec. 20, 1860. The other three happened in 1861.
C. <em>This was a war seen by the Philippinos as a continuation of their independence while it was seen by the american government as an insurrection</em>. The Philippines have been fighting the Spanish Empire since 1896, when the Katiputian (an anti-colonist organization) was discovered by Spanish authorities, leading to 2 years of conflict that ended only when the Treaty of Paris, that ended the Spanish Empire as it was known, ceding the overseas territories of Puerto Rico, Guam and Philippines to the United States.
Even though the Philippinos saw this as a continuation of their fight towards independence, since their country was still owned by other nation than their own, the U.S. saw their continued resistance as an act of insurrection; the Battle of Manila was the initial confrontation of what would scalate to be the Philippine-American war.
Submarines (especially U-boats) played a important role in developing undersea operations as well as changing naval warfare. Gone are the days where all enemies can see each other eye to eye. The development of submarines especially in world war I allowed for submarines to stay longer, take the pressure of water better, and attack enemies better. Torpedoes also got an update that allowed them to shoot straighter, and smaller so that more can be loaded.
However, that is not too say, that u-boats are the only ones that benefited. In a way, ships and planes also developed. The development of Sonar allowed planes to spot submarines and bomb them, as well as for ships to drop depth charges or avoid submarines all together. Ships also were given disruptive camo-patterns that allowed them to have a higher chance of surviving even without weapons loaded on board.
While U-boats during World War I was fairly limited in what they were able to do, they paved the way to a whole new military branch, and changed the dynamics of war in the sea.
