America's War with Mexico

A new book paints a vivid picture of the Mexican War and the men who made it.

A Wicked War: Polk, Clay, Lincoln, and the 1846 U.S. Invasion of Mexico, by Amy S. Greenberg, Knopf, 344 pages, $30.

President James K. Polk was a charmless workaholic who suffered from chronic diarrhea and launched the invasion of Mexico, setting off what Ulysses S. Grant called, with excusable hyperbole, the most "wicked war" ever waged. Starting an unjust war elevated Polk to "near great" status in those Schlesinger polls by which court historians reward warmarkers and punish the peaceful.

The best narrative historians refashion William Carlos Williams's dictum "No ideas but in things" as "No ideas but through persons"; that is, they convey history, and the contending ideas therein, through vivid portraiture. In her absorbing and valuable A Wicked War: Polk, Clay, Lincoln, and the 1846 U.S. Invasion of Mexico, Penn State's Amy S. Greenberg does a splendid job of vivifying this disgraceful episode in American history by following the fortunes of five men (Polk, Henry Clay, Abraham Lincoln, John J. Hardin, and Nicholas Trist) and their families.

The West was considerably more hawkish toward Mexico than was New England, which, as with the War of 1812 and the Spanish-American War, mongered peace. Henry David Thoreau even spent a night in jail protesting the war. But Greenberg's subjects are all men of the South or the West, beginning with Whig Party eminence Henry Clay, lover of "gambling, whiskey, and women," and the Sage of Ashland, his showplace Kentucky estate (worked by 50 slaves).

As speaker of the House, Clay had cawed as loudly as any warhawk in 1812, though in later years he tied his reputation to his "American System" of federally subsidized development. As the presumptive nominee of the Whig Party for president in 1844, he came out against adding Texas to the Union, explaining that "annexation and war with Mexico are identical." Stated Clay: "I regard all wars as great calamities...and honorable peace as the wisest and truest policy of this country."

Clay's rival, ex-president Matty Van Buren, the Sage of Kinderhook (every American town once had its sage), also opposed inviting the Lone Star Republic into the United States. This position crippled his bid for the Democratic nomination, which went instead to James K. Polk, another former Speaker of the House. Polk's chief asset, according to Greenberg, was his stylish and self-possessed wife Sarah, a shrewd assesser of the political scene and abettor of her husband's fortunes.

The Texas-craving Polk edged Clay, despite the latter's backtracking on annexation during the campaign. (This malleable man earned his surname.) Bowing to the election returns, the Senate voted to add Texas to the Union just days before Polk took the keys to the White House from the friendless constitutionalist John Tyler, "His Accidency," a Jeffersonian upon whom Greenberg is too hard.

The dour new president was a Manifest Destinarian, a land-grabbing expansionist like so many Southern and Western Democrats, many of them otherwise advocates of a limited central government. Meanwhile, the Whigs, who preached Clay's American System of a national bank, high tariffs, and federally funded internal improvements, were inclined to peace and often skeptical of the helter-skelter distention of the republic. Even then, the two-party system forced liberty-minded voters to flip a coin.

Polk, who had pledged to serve but one term, entered the White House with "big plans and poor people skills," writes Greenberg. His avaricious eye was on Mexican territory. Texas was the nexus.

By asserting that Texas's southern border was the Rio Grande and not the Nueces River, and by ordering General Zachary Taylor to march his 4,000 men to the Rio Grande—into Mexican-claimed territory—President Polk more or less guaranteed a war with Mexico. (To Polk's annoyance, the war catapulted the Whig Taylor, "Old Rough and Ready," into the White House at the next election.)

The Mexican War featured several battles (Monterey, Buena Vista, Veracruz) containing the usual mix of valor and cowardice, baseness and nobility, and at which reputations were made for acts which from a distance of years savor of the the pyritical (not to mention piratical). It was naked aggression in the service of expansion, of mindless growth (the ideology of the cancer cell, as Edward Abbey used to say), but a supine Congress consented. House debate over Polk's war—sanction for which was attached to a measure funding the soldiers in the field; even then knees went weak upon hearing Support the Troops—was limited, outrageously, to two hours. Only "the immortal fourteen," most famously ex-president John Quincy Adams, voted against Polk's war in the House, while just two senators were brave enough to shout Nay.

The jingo press screeched for blood. The Illinois State Register, for instance, editorialized that Mexicans "are reptiles in the path of progressive democracy." Mexicans were said to be dirty, barbarous, and bewitched by an alien religion.

But not all Illinoisians ached to go abroad in search of reptiles to slay. Greenberg profiles Abraham Lincoln, an admirer of Clay, and John J. Hardin, Clay's step-nephew. Exuding confidence the way other men drip sweat, the elegant patrician Hardin was bound for glory. Then war got in the way.

Hardin and Lincoln were friends, at least until Lincoln proposed that he, former Rep. Hardin, and current Rep. Edward Baker play a round robin with their Illlinois congressional seat. Hardin, contemplating a return to Congress, demurred, and when Lincoln grabbed for the ring in 1846 the affronted gentleman withdrew. Lincoln's ambition, as his law partner Billy Herndon said, was an "engine that knew no rest." The engine ran right over Hardin, who never spoke to Lincoln again.

    Polk's chief asset, according to Greenberg, was his stylish and self-possessed wife Sarah, a shrewd assesser of the political scene and abettor of her husband's fortunes.

    Unfortunately, as first lady, her "Let Us Remain Sedentary!" campaign to get children to put on healthy amounts of fat was a dismal failure.

    "Texas was the nexus."

    oh, please.

    "...but Nevada was teh Baddest?"


    i genuinely expected the story to be about fruit pickers though. because its not like we have a shortage of modern day panic attacks about a slow-motion Reconquista


    also = "Chinese Drywall May Affect You"?

    best. H+R ad. ever.

    It is interesting to me, as a Mexican how little Americans really know about this war. I realize that history is written by the victors and that its perception is normally from the point of view of the one relating the story. In this case, Mexicans know very little about the reasons for the war and the consequences of it is given only a cursory look through the prism of nationalism. Americans on the other hand only encounter it as part of their studies of the Texas rebellion and The Alamo.

    In my opinion, one of the notable events of this war was the St. Patrick’s Battalion. ( It was composed of immigrants to America, mainly Irish who defected the American lines and fought for Mexico because of the mistreatment they endured at the hands of the US command. Today, Ireland and Mexico hold a special relationship because of the Irish who fought on the Mexican side.

    Seeing as it was one of the most immoral wars we ever fought, it's no surprise that American history classes gloss over it. I'm more surprised that Mexicans aren't very knowledgeable about it.

    I'm more surprised that Mexicans aren't very knowledgeable about it.

    Probably this has do to with with the constant instability due to the fighting in the 19th Century between Mexican Conservatives and Liberals. This not only contributed to the Texan Rebellion and Mexico's defeat in the war with the US but also the French attempt to install Maximilian as Emperor. Rather embarassing I imagine and I'm not sure if too many Mexican want to rehabilitate Santa Anna.

    Is that why their flags are sorta the same colors?

    I learned about the Irish defection in high school, and this was in the late 90's. It's pretty common knowledge. The left leaning AP history teachers won't pretends the US was justified in invading Mexico.

    The Irish fought for the confederates
    (also for the union) in the American Civil War. They shot down other Irish at Fredericksburg, the worst union loss in the Civil War. The Catholic church was with slavery for a while.

    Of all the stories from that war, none resonate with me more than the tale of the "Ninos Heroes" of the Mexican Army Military Academy.

    Badass Motherfuckers, to the last kid.

    OK, so let's say we go back in time and prevent the US from going to war with Mexico. Where would the Reason Foundation building be located? Not in its brand new headquarters in Los Angeles, because without the Mexican War there would have been no Winning of the West. The USA would have had the pre-1846 boundaries, which means half or so of the country would not exist. Anyone here who thinks the US War with Mexico was wrong and also lives in any of the territories which the USA gained as a result of that war should immediately pack their bags and leave. The land should then be restored to its original condition.

    As for myself, I enjoy living in an advanced civilization.
