As no agreement could be reached on this point, President Polk ordered General Zachary Taylor to march to the Rio Grande and occupy the disputed territory. 由于不能就此达成一致，珀尔卡总统派扎迦利o泰勒将军远征里约·格兰德并夺取有争议的地区。

334. Taylor's Campaigns. 334．泰勒发起的战役

(2) Scott's campaign, which ended in the capture of the City of Mexico; （2）斯科特发起的战役，这个战役以夺取墨西哥城告终；

and (3) the seizure of California. Taylor's object was to maintain the line of the Rio Grande, then to advance into Mexico and injure the Mexicans as much as possible. （3）夺取加利福尼亚。泰勒的目标是保有里约·格兰德迪战线，并前进到达墨西哥，尽可能多地杀伤墨西哥人。
