James Buchanan

Under the Banner of Heaven

James Buchanan was the president whose decision to send federal officials and troops to Utah brought the Saints and the United States to the brink of armed conflict. The book presents his intervention as both a response to an alleged Mormon insurrection and a political maneuver amid the nation’s deeper dispute over slavery; the resulting Utah War ended by negotiation, but not with the rumors that continued to unsettle the territory.

Political Context

For Buchanan, Utah was a relatively small problem beside the national rancor over slavery, which threatened to divide the country. A pro-slavery Democrat, he saw the Mormon insurrection as an opportunity to distract public attention from that more intractable conflict. The account says he believed a forceful response to pro-slavery Utah might win favor with abolitionists without requiring much political capital, since Mormons were widely reviled.

Buchanan followed the counsel of Robert Tyler, an influential Democratic Party operative and the son of former president John Tyler. The evidence identifies Tyler’s role in advising the president but does not specify the substance of his counsel. The episode thus places federal intervention within both a territorial dispute and Buchanan’s calculation of national political advantage.

The Federal Expedition

In May 1857, alleging that the Mormons had committed numerous treasonous acts, Buchanan dispatched federal officials to restore the rule of law in Utah. The contingent included a new territorial governor intended to replace Brigham Young. Buchanan also ordered 2,500 heavily armed soldiers to escort the officials to Salt Lake City and subdue the Saints if necessary. The scale of the deployment made the confrontation resemble a declaration of war.

The Utah War, however, produced more spectacle than combat. Historians compared it to a comic opera: the United States had sent the largest peacetime army in its history to oversee the installation of a handful of officials in a minor territory. A concord was negotiated before the Saints and American soldiers exchanged a single shot. The contrast between the formidable force Buchanan ordered and the bloodless resolution defines the episode’s central irony.

Resolution and Aftermath

In 1858, Brigham Young reluctantly agreed to admit federal troops into Utah and leave the territorial governorship, ending the threat of all-out war between the Saints and the United States. That settlement resolved the immediate standoff, but it did not settle the questions of trust and responsibility surrounding the Mormon settlements.

Persistent rumors that Mormons had committed atrocities against the Fancher wagon train continued to rise from the southern settlements, threatening the fragile peace. Buchanan’s intervention therefore ended without a battlefield conclusion, while the political and public anxieties surrounding Utah remained alive.

Narrative Significance

Buchanan’s role is brief but consequential: his choice to use federal power transformed allegations of treason into a military confrontation, while the absence of fighting exposed the disproportion between the expedition’s scale and its outcome. His decision is also framed by the national politics of slavery, showing how a territorial crisis could be used to pursue advantage in a much wider conflict. The negotiated end avoided open war, but the account’s emphasis on rumors afterward prevents that settlement from reading as a complete or lasting reconciliation.
