elations between Mexico and the US went sour and war broke out in 1846 over a boundary dispute. American troop strength, however, was too low to even consider fielding a foreign occupation force. When the Secretary of War therefore issued a call for 2,800 Tennesseans to join the ranks, 30,000 responded! This cinched the nickname "Volunteer State" first earned during the War of 1812.

Storming of Fort Teneria at the Battle of Monterey, September 21-24, 1846

In a battle with particular significance to Tennesseans, Tennessee regiments under Gen. Gideon Pillow and future governor Colonel William Bowen Campbell stormed over the fort walls with bayonets and swords. It was Campbell who gave the famous command, "Boys, follow me!" William B. Allen of Lawrence County was felled leading a charge at Monterey and died exhorting his company of Lawrence Blues to take the fort. Both the First and Second Tennessee Infantries fought bravely in the battle despite widespread illness and terrific losses. First over the walls and into the fort was the First Tennessee, and it was at the Battle of Monterey that the regiment earned the nickname the "Bloody First."

The First Tennessee Infantry joined Quitman’s Brigade in 1846 and stormed Fort Teneria during the Battle of Monterey.

Look up the following Tennesseans:

General John A. Quitman and the storming of Fort Teneria during the Battle of Monterey.

Colonel Benjamin Franklin Cheatam and his involvement in the Battle of Monterey and the Mexico City campaign.

Major Adolphus Heiman and his work in the Battle of Monterey.

Tennessee troops vs Santa Anna at The Battle of Cerro Gordo.

But, sure...Tennessean involvement in Texas history is limited to Davey Crockett and The Alamo.
