In 1863, Carson was ordered to do what?

In 1863, Christopher "Kit" Carson was tasked with leading a military campaign against the Navajo people, specifically to subdue them during the broader context of the Civil War era. The U.S. government aimed to assert control over the Navajo territory and resources, which were vital for both military strategy and westward expansion.

This action was part of a larger military strategy known as the Campaign Against the Navajo, which sought to quell resistance from the Navajo population who were defending their land and way of life from encroachment by American settlers and military forces. Carson was chosen for this mission due to his extensive experience as a frontiersman and his previous interactions with various Native American tribal groups.

Other options listed do not align with Carson's historical actions in 1863. Guiding hunters, leading a column against the Mexicans, or guiding a wagon train across the Santa Fe Trail reflect different contexts or events in his life and career, which do not take precedence during this specific year when the focus was heavily on the conflict with the Navajo.
