The SGS Halls of Montezuma game contains many scenarios, covering different periods of the Mexican-American war of 1846-1848. The war was initiated by US President Polk on the premise that the southern border of Texas should be he Rio Grande River, while Mexico claimed that the border was on the Nueces River. The Whig party and many American citizens opposed the war, and this is a decisive factor in the game. Small scenarios cover the early stages of the war over the disputed territories in southern Texas or, in the West, in California and New Mexico. Another scenario deals with Scott’s famous 1847 campaign, starting with the landing at Vera Cruz till the capture of Mexico city. And, of course, a complete Grand Campaign covers the whole war.

Scenario durations last from 8 turns (for the smaller ones) to over 44 turns, each representing a two-weeks period between April 1846 and March 1848.

One player represents the United States of America’s land and naval forces, the other has Mexico’s land and Naval forces.

• The Mexican forces are more numerous at the start of the game, but are poorly led and have lower morale. They receive only a small number of reinforcements and must hold desperately against the onslaught and superior morale of their enemy, hoping to gain enough time for America’s internal politics to disrupt and eventually end the war.
• The USA must advance and eventually conquer Mexico City before the Whig opposition to the war forces a negotiated peace. This anti-war sentiment is represented in the game and shall be carefully watched. The starting forces are small initially, but supplemented many Volunteers and further reinforced by regular Army units. And the US Navy dominates the seas, giving a sizable strategic advantage.

Be careful of the potential weakness of some quality but small units. As the USA, losing regular army units will seriously affect the anti-war sentiment at home. Watch your supply assets, as early success may easily outrun your capacities in the logistical nightmare of Mexico in the early 19th century.
