I’ll give you two:
Yes: The “War” on the Indians was not a traditional war of declaration but of skirmishes. When wagon trains of people headed West Indians would commonly target them for raids and pillage, so along many routes forts where built and patrols would try and make sure they were safe. If the problem became worse the local garrison would find the tribe and come with a list of demands. Most of the time they were fired upon arrival out of fear or anger. This would lead to a small battle or skirmish which would likely cause collateral damage.
No: The wars raged in the west against the Indians were that of near genocide, and to call it anything but is misleading. To claim that the slaughter of hundreds of innocent people was a “battle” is absurd and shouldn’t be considered. Though in films that depict such events are dramatized and inaccurate, situations much like those were taking place around the west yearly.
Answer: Who: United States, President James Polk, General Taylor, Col. Kearney, Commodore Stockton and others vs. Mexico, General Santa Anna
What: Dispute about the border, whether or not Texas could be part of the USA, and belief of many US citizens that there was a "manifest destiny" that the country extended all the way from the Atlantic Ocean to the Pacific Ocean and include Texas, California, and the territory in between that had been part of Mexico.
When: April 1846 to February 1848
Where: War began at Coahuila, near the Rio Grande River. Included battles at Monterey, Buena Vista, Vera Cruz, Puebla and other places. Ended at the Battle of Chapultepec in Mexico City. Treaty of Guadalupe Hidalgo ended the war.
How: The USA had superior weapons, especially artillery and cannons. The Mexican government was disorganized, not prepared for war. Mexican troops suffered disease, fatigue, and desertion. When the US won, Mexico gave up the disputed territory extending from Texas to California and the USA paid 15 million dollars to Mexico for the territory.
Explanation:
Had no effect on the war I think because it was fought after the treaty was already signed.
They can co-sponsor a bill in the house of representatives. So it is TRUE
