The Rio Grand River does NOT serve as a physical divider between Mexico and Canada. Instead it serves as part of the border between Mexico and the United States. The Rio Grande and the Rio Bravo del Norte are two different names for the same river TRUE.
I can't really answer this for you because this is YOUR opinion but here's what I would've said; Yes, I would have because of the extreme hardships the militia men had to go through. During that winter, many soldiers had suffered the consequences of going through and not quitting the journey but if I were one of them, I would've quit. Even though I know that I have to fight for the country, I would not have been able to go through with the lasting consequences. Men had to walk through treacherous snow which also was cold and wet, this was not a good environment for soldiers to be in.
