Clark's 1,700 or 1,800-man column consisted of his own brigade (under the command of Colonel
Colton Greene), 500 men from Colonel
Sidney D. Jackman's brigade, and
Harris's Missouri Battery. Clark and Jackman were selected for the operation because they were local residents. The column pushed north and then crossed the Missouri by
ferry at
Arrow Rock on the 14th. After hearing rumors that the garrison of Glasgow had a "
tin-clad boat", Clark asked Price for more artillery. In reality, the Union vessel present, the steamer
West Wind, was not tin-clad or even armed. Since the river at Glasgow was narrow enough for artillery to effectively fire across it, Price sent Brigadier General
Joseph O. Shelby with 125 cavalrymen and part of
Collins's Missouri Battery to a point on the western bank of the Missouri opposite Glasgow. Shelby's force was joined by some of Anderson's guerrillas, but Anderson and his men did not participate in the fighting. The Union garrison was initially a small force under the command of
Captain John E. Mayo, but it had been reinforced on October 13 by part of the
43rd Missouri Infantry Regiment under the command of Colonel Chester Harding. The Missouri infantrymen had been temporarily stranded when the
steamboats they were on ran aground. Once the ships were freed, they went downriver to Glasgow, where they unloaded the Missourians and supplies. One of the ships,
Benton, returned to Jefferson City, while the other,
West Wind, stayed at Glasgow, as its
draft was expected to be too deep for the falling water levels on the river. Harding, who was now in command of the garrison at Glasgow, had between 550 and 800 men available, including armed civilians. The Union force had no artillery available. Glasgow's location on a hilltop provided an advantage to the defenders. The interior Union line was anchored by two unfinished fortifications which held about 40 men each. The defenses between the fortifications were makeshift, although they had been extended to the east to a schoolhouse. Most of Harding's men were positioned outside the fortified line where the roads entered town. This interior line ran from near the river to the east edge of town, before curving to the north. Elements of the 43rd Missouri Infantry held east and west positions south of town on the external line, near where the roads crossed
Greggs Creek. In between those two positions, a line of local militiamen was posted. The two road crossings were over apart. The line south of town ran roughly east to west. North of the town, a group of cavalry, largely members of the
Missouri State Militia, held a position north of Bear Creek, crossed by a single road. A militia force was sent east to repair telegraphic connections with Jefferson City, but returned to Glasgow late on October 14 after running into a Confederate force. At around 05:00 on October 15, Collins's Battery opened fire, aiming primarily for
West Wind, visible campfires, and exposed streets in the town. This fire was largely ineffective, as was fire from the cavalry accompanying the cannons, although a prominent pro-Confederate civilian, clergyman
William Goff Caples, was killed by an artillery shot. Union
sharpshooters drove some Confederates away from the riverbank. Clark's force, delayed an hour while trying to cross the Missouri River, arrived later than Shelby expected. Clark was three miles away when Collins opened fire. By about 07:00, Clark's men finally arrived on the field. Jackman's men were aligned to the left, closer to the river, with most of the rest of the Confederate force to Jackman's right. The
3rd Missouri Cavalry Regiment held the extreme Confederate right. The
10th Missouri Cavalry Regiment was sent around the Union rear to attack Glasgow from the north. Greene had one of Harris's cannons brought to the front. Harding responded by reinforcing the Greggs Creek line with several companies of the 43rd Missouri. Clark sent a surrender offer to Harding, using civilians to deliver the message. The Union commander was confused by the nonstandard use of civilian messengers, and rejected the offer. Clarks' main body south of town forced its way across Greggs Creek beginning around 08:00, although the Union defenders put up a hardy fight. In his after-battle report, Harding stated that his men had been
outflanked on both ends of their line. The Union troops fell back into the prepared position in Glasgow proper. They came under fire from the Confederate artillery on the opposite side of the river, which was more effective this time.
West Wind had been damaged by artillery fire. Shelby ordered men across the river in a small boat to
West Wind, hoping to take
West Wind to use it as a ferry across the river. The Confederates reached
West Wind but found the steamboat's engines had been rendered nonfunctional, and they had to return to Shelby. Meanwhile, the 10th Missouri Cavalry's drive from the north had been stymied by the Missouri State Militia force north of town. Confederate troops closed in on the Union line in Glasgow. Clark described the distance between the two sides as "short"; Harding estimated the distance at to .
House-to-house fighting ensued. Harding conducted a
council of war, which resulted in the decision to surrender. Before surrendering, Union troops burned 50,000 rations in Glasgow's City Hall to prevent them from falling into Confederate hands. The fire spread to other buildings, causing $130,000 in damage. Additional supplies were not burned because they were kept in positions near the river that were inaccessible. The surrender took place around 13:30, and its terms allowed captured Union officers to keep their horses and
sidearms. Harding and his men were
paroled and escorted to a Union position on the
Lamine River. The escort was provided to protect them from guerrillas. A Confederate officer conducted a ceremony where the Union soldiers were sworn not to serve against the Confederates again, although this was not part of the agreed surrender terms. ==Aftermath==
