91st Illinois Infantry Regiment
The 91st Regiment Illinois Volunteer Infantry was an infantry regiment that served in the Union Army during the American Civil War.[1][2] ServiceThe regiment was organized at Camp Butler, Illinois, in August 1862,[3] by Col. Henry M. Day, and was mustered on September 8, 1862.[3] Armed with smoothbore, .69 -caliber Springfield Model 1816s altered from flint-lock to percussion, the 91st Illinois left the state October 1, for the front, and arrived at Shepherdsville, KY, on Tuesday, October 7. Initial operations, surrender, and paroleThe regiment was assigned to the Department of the Ohio's Railroad Guard to counter Confederate partisan and cavalry attacks on the Louisville and Nashville Railroad (L&NRR).[3] Its primary opponent from October through December was Brig. Gen. John Hunt Morgan's regular and irregular cavalry.[4][note 1] On Saturday morning, December 27, 1862, the recently married Morgan arrived in force at Elizabethtown, KY,[3] where the 91st was then stationed behind fortifications, under Lieut. Col. Harry S. Smith. Morgan had captured the regiment's three detached companies guarding the railroad at Nolin Station and Bacon Creek[2] on Friday. Morgan and Smith sent notes to each other demanding each other's surrender.[7] At an impasse at 1:30 P.M., Morgan's artillery batteries began bombarding the remaining seven companies and his cavalry opened up with their musketry. Soon, the inferiority of the smoothbore muskets, exhaustion of the ammunition, and Morgan's superior numbers, caused Smith to sue for surrender.[4] Morgan paroled the regiment after taking their arms.[note 2] The regiment's loss was seven killed, and several wounded, some of whom died of their wounds. As they were paroled, they noted that the rebel loss in killed and wounded exceeded 200.[7] On Sunday,December 28, the 91st took the route step for Louisville, KY, where all the well men took the Mobile and Ohio Railroad (M&ORR) to Columbus, KY. There they took steamboats across the Ohio River to Cairo, IL and then rode the Illinois Central Railroad for St. Louis, MO.[2] Only seven men reached St. Louis, and reported at Benton Barracks on Thursday, January 1, 1863.[7] The remainder of the regiment interpreted their parole as license to go home and abandoned the train at points along the line in Illinois. Most of the officers got as far as East St. Louis before they went home. About two-thirds of the Regiment answered at roll-call at Benton Barracks on Saturday, February 28, 1863, to muster for six months pay. From then until Friday, June 5, all but a few reported back to the regiment's headquarters at Benton Barracks.[7] On that day, the regiment's was exchanged and cleared for operations. Return to active dutyAs a result of the exchange, the men were re-equipped, resupplied, and re-armed .69-caliber M1842 muskets that had been rifled at St. Louis Arsenal[7][9][note 3] With their new arms, equipment and supplies, the men of the 91st began at once training and drilling.[3] While in St Louis, they were reassigned from the Department of the Ohio, soon to be the Army of the Cumberland, to the Department of the Missouri. During this tenure, the three victorious U.S. campaigns of Gettysburg, Tullahoma, and Vicksburg occurred. On Wednesday, July 8, the Regiment mustered and received four months pay.[7] Reassigned to the Army of the Tennessee, fresh off its victory at Vicksburg, the 91st Illinois alongside 29th Illinois, embarked on the steamboat Nebraska that afternoon. The boat cast off from St. Louis, steamed down the Mississippi, and disembarked at Vicksburg, a week later, at 7 p.m. on July 15.[3] Once there, the regiment was assigned to the 2nd Brigade, Maj. Gen. Herron's 2nd Division, in Maj. Gen. Ord's XIII Corps.[3][note 4] With its new command, the 91st Illinois suffered heavy losses in effective men due to bad drinking water.[7][note 5] To support Maj. Gen. Banks' Army of the Gulf's plans to extend the blockade around the Confederacy by sealing the border with Mexico, Grant had Sherman detach Ord and ordered XIII Corps to join Banks at Port Hudson. The corps left Vicksburg, Friday, July 24, arriving at Port Hudson on Saturday. While there, the 91st Illinois patrolled and scouted the surrounding country reasserting federal control.[7] On Thursday, August 13, Banks began moving his army back to New Orleans, LA, to continue regaining U.S. control of the Gulf Coast.[3] The 91st Illinois remained at New Orleans until Saturday, September 5th, when Herron's division detached from XIII Corps. The division took steamers up the river, landing at Morganzia Bend on Sunday midday.[3] Monday morning, September 7, the 91st, 94th Illinois, 20th Wisconsin, and a battalion of the 2nd Illinois Cavalry, with two cannons, started west for the Atchafalaya River.[13] About sundown they made contact with the enemy but were rebuffed and fell back six miles. Regrouping, the force attacked again on Tuesday, driving the enemy across the river taking 200 prisoners.[3] With the rebels driven out of the area, on Wednesday, the 91st Illinois fell back to the Mississippi,[13] and on Friday, September 10, to take possession of Morganzia, LA.[3] The regiment remained in garrison at Morganzia a month, and on Saturday, October 10,the 91st Illinois boarded steam transports for New Orleans.[3][14] Arriving arriving there the next day, the regiment turned in their M1842 rifled-muskets and received new .577-caliber Pattern 1853 Enfield rifled-muskets.[13] The 91st Illinois was assigned to the Brig. Gen. Vandever's 1st Brigade,[note 6] of Maj. Gen. Dana's 2nd Division, XIII Corps,[note 7] in Banks' Army of the Gulf. General Vandever commanding. For the next ten days, the regiment was on duty as patrolling New Orleans and its environs.[13] South Texas ExpeditionIn the fall of 1863, the Union wanted to shut down the last holdouts on the Texas coast. Banks would send his XIX Corps under the Antietam veteran Maj. Gen. William B. Franklin to take the Sabine Pass at the Luisianna-Texas state line.[note 8] Meanwhile, at the other end of the Texas coast, Banks and his XIII Corps would shut the port at the Corpus Christi/Brownsville area at the mouth of the Rio Grande.[16] Another issue for seizing Brownsville was the U.S. government was also anxious to show Union presence along the Mexican border since the French Army had just invaded Mexico and installed Maximillian, and there was an increasing tension and hostility with the French and Imperial Mexican forces. The Union planned to shut down the port and at the same time give a boost to Juárez.[17] Here, Confederate forces, under Brig. Gen. Bee consisted of only four companies from the 33rd Texas Cavalry under Col. James Duff and another two companies of three-month volunteers. All other Confederates along the coast had been called elsewhere in the wake of Franklin's failed attack. The total Confederate force amounted to roughly 150 men stationed at Fort Brown. On Friday, October 23, the 91st's division sailed for Texas, via Mississippi River and Gulf of Mexico. The expeditionary force and its small fleet of steamer transports and towed sailing supply vessels arrived at the mouth of the Rio Grande shortly after noon, November 1, 1863.[18] On Tuesday November 3, the 91st landed at Point Isabell. On November 4 after unloading all necessary arms, supplies, and equipment, the XIII Corps moved west to Clarksville at the mouth of the Rio Grande. On Friday, Dana's 2nd Division started for Brownsville, Texas, skirmishing all the way with Bee's troops Battle of BrownsvilleVandever's 1st Brigade followed Col. Dye's 2nd Brigade[note 9] as it led the advance up the river on Brownsville.[13] The 1st Texas Cavalry screened the force as it advanced.[note 10] After chasing off Duff's cavalry, Dye's men entered the Brownsville around 10:00 a.m., on November 6, 1863.[24] As the Union forces spread out through the city. General Bee quickly ordered the evacuation of the city and abandoned Fort Brown. He personally supervised the burning of what military supplies and cotton he could. Inside the fort was 8,000 pounds (3,600 kg) of condemned explosives which caused a great explosion much to the terror of the local citizens.[25] The Confederates' destruction spread into the city while the soldiers resorted to looting prompting the local citizens into a degree of opposition. A local resident by the name of General José Maria Cobos was a Mexican general and refugee living in exile due to the recent French invasion. General Cobos received permission from the civilian authorities in Brownsville to organize a force to resist the looters and subdue the fires started by the Confederate evacuation.[26] Around noon General Banks personally arrived in the city and by 4:00 pm the remaining Union forces arrived. Colonel Dye was put in command of the post and the Union army encamped in the city, the army barracks at Fort Brown having been destroyed. The Union forces also captured a large supply of cotton left behind by the Confederates. Chaos in MatamorosShortly after helping stop the looting and the fires in Brownsville, General Cobos led a force across the river and seized Matamoros. Banks was in communication with Secretary of State William Seward and keeping Washington informed of the political situation in Mexico. The French had sought and received Confederate support while aiding the Confederacy when and where they could.[27] The Union consistent with its desire to preserve its republic supported the Republicans under Juarez. Cobos while no friend of the Hapsburgs nor French was also a conservative reactionary who denounced Juarez as a demagogue. Cobos had received the support of the local bandit chieftain, Cortina[27] to take power, but they fell out the next day and Cortina executed Cobos. The 19th Illinois and other men of XIII Corps were witness to this chaos across the river and were kept on alert[28] during the remainder of their stay in Brownsville. Banks took the unoccupied Fort Brown on Monday November 9.[13] The regiment was mustered out on June 12, 1865, and discharged at Chicago, Illinois, on June 28, 1865. Total strength and casualtiesThe regiment suffered 12 enlisted men who were killed in action or who died of their wounds and 1 officer and 131 enlisted men who died of disease, for a total of 144 fatalities.[29] CommandersSee alsoReferencesFootnotes
