Congress has authorized the raising of a regiment of mounted riflemen and the establishment of military stations along the Oregon route, allocating $76,500 for the effort. The act, signed by President James K. Polk on May 19th, calls for a full regiment composed of one colonel, ten companies of infantry, blacksmiths, and farriers—all entitled to the same pay and provisions as dragoons. A separate resolution authorizes temporary mail service in Texas following its recent admission to the Union. But the real fire on this page comes from Senator Pennybacker of Virginia's lengthy congressional remarks on the Mexican-American War. Drawing on international law scholars like Bynkershoek and Sir William Scott, Pennybacker argues that war need not be formally declared to exist—hostile acts and military concentration are sufficient proof. He catalogs Mexico's years of grievances over Texas annexation, the rejection of American diplomatic missions, and the Mexican general's ultimatum demanding U.S. troops retreat beyond the Nueces River or face armed conflict. The speech reads as a legal brief justifying military action already underway, with Pennybacker insisting the evidence of war is overwhelming.

This newspaper captures America at an inflection point. The Mexican-American War, which began in May 1846, would reshape the nation's borders and reignite the slavery debate that would tear the country apart fifteen years later. The acquisition of vast southwestern territories—present-day California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming—would force Congress to confront whether slavery could expand into these new lands. Pennybacker's legalistic defense of war without formal declaration also reflects how Congress was grappling with executive power during wartime, a tension that would echo through American history. The simultaneous push westward (Oregon stations) and southwestward (Mexico) shows an America aggressively expansionist, driven by what many called Manifest Destiny.

• The Mounted Riflemen Regiment included two positions almost never mentioned in military histories: each company had one 'terrier' and one 'blacksmith.' The terrier's actual role remains mysterious in the legislative text—possibly for pest control in frontier camps, possibly something else entirely.
• Daguerreotype portraits could be taken 'in any weather in exquisite style' at Plumbe's National Daguerrean Gallery, which had locations in nine cities from Boston to Louisville. The firm had been awarded 'the medal, four first premiums, and two highest honors' by institutes in Massachusetts, New York, and Pennsylvania—an early form of corporate brand-stacking.
• Charles de Fielding, a notary public and claims agent, advertised his services for 'procuring pensions, whether revolutionary or any other service'—meaning he was still processing pension claims from the American Revolution, seventy years after it ended.
• The appropriation for compensating Indian tribes whose land would host military stations was capped at $2,000 total 'for each nation'—an extraordinarily small sum even for 1846, suggesting how little the government valued indigenous land rights.
• F Street Presbyterian Church was undergoing improvements significant enough that the entire congregation had to relocate to 'the session room attached to, and immediately in the rear of the building'—a detail suggesting the renovation was substantial mid-construction.

• Pennybacker's citation of the 1812 U.S.-Britain war as precedent is revealing: he notes hostilities began 'as soon as the act of Congress was passed, without waiting to communicate to the English government any notice of our intentions.' The Mexican-American War followed the same playbook—Congress authorized force, and fighting had already begun.
• The mounted riflemen regiment authorization came just days before the Battle of Palo Alto (May 8, 1846) and the Battle of Resaca de la Palma (May 9, 1846)—meaning Congress was formally organizing troops for a war already bloodily underway. The legislative response was always trailing the military reality.
• Pennybacker invokes the Peace of Versailles (1763) as the turning point when formal war declarations fell out of fashion among European powers. He's arguing that America should follow European practice—a ironic appeal to Old World tradition by someone defending aggressive westward expansion.
• The bill's authorization of $76,500 for 'mounting and equipping' the riflemen regiment converts to roughly $2.2 million in 2024 dollars, yet the Indian compensation fund was capped at $2,000 total—suggesting the government valued cavalry horses and saddles roughly 1,000 times more than it valued treaties with indigenous peoples.
• Texas mail service required a temporary legislative patch because Texas had just joined the Union on March 1, 1846, and its postal infrastructure hadn't been integrated into the federal system. This Resolution was essentially a bureaucratic Band-Aid, resolving the chaos of rapid territorial expansion.
