Order of Battle for Churubusco, August 20, 1847

I thought I post the OB for this scenario.  It has an awesome mix of troop types.  


The Mexican-American War
August 20, 1847 Churubusco, The Campaign on Mexico City 

   As the American forces, led by General Winfield Scott, began the final offensive on Mexico City, the Mexican defenses collapsed at the battles of Contreras and San Antonio.  Remnants of the Army of the Center fell back to the village of Churubusco, just 5 miles from the capital.

   The Mexicans made their stand at the Franciscan convent of Santa María de Churubusco. Although the convent offered no advantage of height over the surrounding terrain it was positioned to protect a bridge over a small river that the U.S. forces had to negotiate to take the position. In addition to the stone walls of the convent, the defenses included a series of incomplete trenches the Mexicans had begun digging prior to the attack.

   Numbered among the Mexican defenders was the Saint Patrick's Battalion, known as the San Patricios.  The unit was made up of American deserters, mostly of Irish descent, who deserted in protest to their treatment in the U.S. Army.

   The approaching U.S. forces merged with pursuing forces coming from Contreras to assault the Mexican position which was now almost all that stood between them and the capital.
