A major goal and outcome of the Sibley expedition involved

A. collecting soil samples of the Great Plains
B. claiming Oklahoma land for the United States
C. establishing peaceful relations between Americans and important American Indian tribes
D. demonstrating that the Great Plains had rich mineral deposits to mine

D, right?

the answer is D

Negotiated relatively safe traffic through Indian lands from Missouri west

No, the correct answer is C. establishing peaceful relations between Americans and important American Indian tribes. The Sibley expedition, led by Henry Hastings Sibley in 1863-1864, was a military campaign in the American Civil War that aimed to secure the New Mexico Territory for the Confederacy. However, one of the major goals of the expedition was to establish peaceful alliances with Native American tribes in the region.

To determine the correct answer for this question, we can break it down and critically analyze each option.

A. Collecting soil samples of the Great Plains: Although collecting soil samples might have been a part of the Sibley expedition, it does not represent a major goal or outcome of the expedition as a whole.

B. Claiming Oklahoma land for the United States: While the Sibley expedition took place in the mid-19th century when the United States was expanding westward, there is no evidence to suggest that claiming Oklahoma land was a major goal or outcome of this particular expedition.

C. Establishing peaceful relations between Americans and important American Indian tribes: This option aligns more closely with the primary goals and outcomes of the Sibley expedition. Exploratory expeditions during this time period often aimed to establish peaceful relations with Native American tribes and gather information about their territories.

D. Demonstrating that the Great Plains had rich mineral deposits to mine: There is no indication that the primary purpose of the Sibley expedition was to survey the Great Plains for mineral deposits. While the exploration of resources was an important aspect of westward expansion, it was not the focus of this particular expedition.

Based on this analysis, the correct answer is indeed:

C. Establishing peaceful relations between Americans and important American Indian tribes.
