About George W. Morgan

Lived 1820 – 1893 (aged 72). George W. Morgan was an American politician, military officer, lawyer and diplomat.

George Washington Morgan (September 20, 1820 – July 26, 1893) was an American soldier, lawyer, politician, and diplomat. He fought in the Texas Revolution and the Mexican–American War, and was a general in the Union Army during the American Civil War. Morgan later served as a three-term reconstruction era United States Congressman from Ohio. He also served as the United States Ambassador to Portugal from 1858 to 1861, during the term of President James Buchanan.

Early life and career Morgan was born in Washington County, Pennsylvania, to a prominent family. His grandfather, Col. George Morgan, was the first to give President Thomas Jefferson the information regarding Aaron Burr's conspiracy. G. W. Morgan was educated in local schools, and then in 1836, he withdrew from Washington College at the age of 16 and enlisted in a military company that was commanded by his older brother, Thomas Jefferson Morgan. They traveled south to Mexican Texas to fight in the struggle for independence from Mexico. Morgan received a commission in the regular Texas Army under Sam Houston as a lieutenant, and rose to captain commanding the post at Galveston. He served with Captain Robertson's rangers and Company B of the First Regiment of Texas Rangers. He resigned in 1839 to return to Pennsylvania.

In 1841, he entered the United States Military Academy, but left in 1843 due to poor grades. He moved to Mount Vernon, Ohio, studied law, passed the bar exam, and established a law practice there in 1845. He served as prosecutor for Knox County.

When war erupted with Mexico, Morgan was appointed Colonel of the 2nd Ohio Volunteer Infantry. He subsequently was commissioned as Colonel of the 15th U.S. Infantry in March 1847, serving under General Winfield Scott. To put an end to the guerrilla warfare and murder of American soldiers, Colonel Morgan seized a number of prominent Mexican citizens and issued a proclamation announcing that for every American soldier killed by the guerrillas, a citizen would be executed. The murders ceased at once. He was breveted to brigadier general in 1848 for his gallantry at the battles of Contreras and Churubusco, where he was severely wounded. Returning to Ohio to recuperate, he received the formal thanks of the Ohio legislature.

Morgan resumed his law practice in Mount Vernon. He married Sarah H. Hall of Zanesville, Ohio, on October 7, 1851, and they had two children.

In November, Morgan served with Maj. Gen. Jacob D. Cox in western Virginia (now West Virginia) in the Kanawha River Valley, defending Charleston.

The following year, Morgan commanded the 3rd Division of the XIII Corps under Maj. Gen. William T. Sherman during the Vicksburg Campaign. Sherman, however, was upset with Morgan's performance at the battle of Chickasaw Bluffs, when he failed to carry out orders for a planned attack.

Death and burial Morgan died at Fort Monroe, Virginia on July 26, 1893, the last surviving general of the Mexican-American War. He was buried in Mound View Cemetery in Mount Vernon, Ohio.
