The two sides engage in fierce hand…
May 1846 CE
The U.S. Cavalry manages to capture the Mexican artillery, causing the Mexican side to retreat—a retreat that turns into a rout.
Fighting on unfamiliar terrain, his troops fleeing in retreat, Arista finds it impossible to rally his forces.
Mexican casualties are heavy, and the Mexicans are forced to abandon their artillery and baggage.
Fort Brown inflicts additional casualties as the withdrawing troops pass by the fort.
Both these engagements are fought before war is declared.
