The 12th Maine Infantry Regiment was an infantry regiment that served in the Union Army during the American Civil War.^[1]

The 12th Maine Regiment, formed in November 1861, was one of the 10 regiments Major General Benjamin F. Butler of Massachusetts received permission to form.^[1]

George F. Shepley a Democrat and a noted Portland lawyer and U.S. Attorney for Maine, headed the new regiment.^[2]

On October 1, 1861, Shepley wrote to Maine Governor Israel Washburn Jr. to report that he expected the new 12th Maine Regiment to be filled soon "with the very best men in the State."^[2]

Shepley also reported, "I have abandoned every other thought and pursuit, and have embarked in this movement all my hopes energies and efforts and, if need be my fortune and my life."^[3][1]

The 12th Maine in Louisiana

According to The New York Times, "The town of Madisonville, La., on the other side of Lake Pontchartrain, has been captured without resistance and is now garrisoned by our forces. The expedition consisted of a portion of the Maine Twelfth, the Connecticut Ninth, two battalions from the convalescent camp of the Thirteenth Corps, the Massachusetts Fifteenth battery, battery of the United States artillery and a company of the Louisiana Second cavalry, the whole under the command of Col. Kimrall, of the Maine Twelfth.

The 8th of January was observed by a salute at meridian by order of Gen. Banks.

The great Union mass meeting was held here the same night at the St. Charles Theatre, which was crowded from pit to dome, including a large number of planters from up and down the river. Speeches were made by Messrs. Flandres, L. Madison Day, and Thos. J. Durant."^{[4][2] [5] [3]}

"The oddest pets we have yet seen were two bears, which the 12th Maine regiment of the 19th Corps, led through the city recently. These bears were brought all the way from Louisiana, and have been in several fights. They have become perfectly tame and tractable, and march along at the head of the band, with an air that indicates they feel themselves veteran soldiers of the bruin order, and that they have a character to sustain."^[9]
