Mexican-American War cover

-In Pursuit of Manifest Destiny-

March across the plains of southern Texas with the 4th US Infantry which included in its ranks the young Lieutenant Sam Grant.

Accompany the elite US Engineers, its members including Lee, Beauregard, McClellan, Joe Johnston and other soon-to-be-famous officers, as they pry into the Mexican dispositions to find an opening that would lead to victory.

Bounce across the arroyos at Buena Vista on the seat of a caisson in a battery commanded by Captain Braxton Bragg, or ride with the US Dragoons alongside Dick Ewell, back in the days when he still had hair.

Mexican-American War is a grand tactical level simulation of this conflict using the Early American Wars engine.

The war with Mexico presents some fascinating parallels and contrasts with our current history.

Mexico in 1846 had a standing army of about 35,000 men, while the Regular Army of the United States mustered only about 7,000 soldiers, with most of them scattered across the western borders of the country, protecting settlers and battling Indians.

Employing advanced tactics and superior technology, especially that of the artillery, the US prevailed. Luck, boldness, and skill also contributed to the US victory.

You have an opportunity with this game to rewrite the history of a forgotten war, fought in 1846 and 1847 between The United States of America and the nation of Mexico.

In scope, from the sweeping panorama of deserts and mountains, to lush California to Mexico City's verdant basin, the war is unrivaled in the Western Hemisphere, even by the American Civil War which began only fifteen years later. From Texas to the Pacific, from Northern California to Central Mexico, battles, skirmishes - and diplomacy - over a period of two years determined the ultimate outline of the continental United States as we know it today.

You will also do battle in a conflict only slightly better known to Americans - the Texas War of Independence, fought in 1835-36. From "Come and Take It!" to "Remember the Alamo," you will fight until the decisive battle of San Jacinto settles the issue.

With Mexican-American War you can choose from 72 stand alone scenarios and 5 campaigns.
