Cherry Grove

Moving northward through the western part of Marion, the eastern portion of Knox, and the western border of Lewis counties, Porter approached Sulphur Springs, near Colony, in Knox County. Along his route he collected perhaps 200 recruits. From Sulphur Springs he moved north, threatened the Union Home Guards at Memphis, picked up additional recruits in Scotland County, and moved westward into Schuyler County to get a company known to be there under Captain Bill Dunn. Union forces under Colonel Henry S. Lipscomb and others responded with a march on Colony. They overtook Porter at Cherry Grove, in the northeastern part of Schuyler County, near the Iowa line, where, with a superior force, they attacked and defeated him, routing his forces and driving them southward. Losses on both sides were minor. Porter retreated rapidly, pursued by Lipscomb, until his forces dispersed at a point about 10 miles west of Newark. Porter, with perhaps 75 men, remained in the vicinity of his home for some days, gathering recruits all the time, and getting ready to strike again.

Memphis

On Sunday, July 13, Porter approached Memphis, Missouri in four converging columns totalling 125–169 men and captured it with little or no resistance. They first raided the Federal armory, seizing about a hundred muskets with cartridge boxes and ammunition, and several uniforms (Mudd, see below, was among those who would wear the Union uniform, as he claimed, for its superior comfort in the heat, a fact which would later draw friendly fire and aggravate the view of Porter's troops as bushwhackers, neither obeying nor protected by the rules of war). They rounded up all adult males, who were taken to the court house to swear not to divulge any information about the raiders for forty-eight hours. Porter freed all militiamen or suspected militiamen to await parole, a fact noted by champions of his character. Citizens expressed their sympathies variously; Porter gave safe passage to a physician, an admitted supporter of the Union, who was anxious to return to his seriously ill wife. A verbally abusive woman was threatened with a pistol by one of Porter's troops, perhaps as a bluff; Mudd intervened to prevent bloodshed. Porter's troops entered the courthouse and destroyed all indictments for horse-theft; the act is variously understood as simple lawlessness, intervention on behalf of criminal associates, or interference with politically motivated, fraudulent charges.

At Memphis, a key incident occurred which would darken Porter's reputation, and which his detractors see as part of a consistent behavioral pattern which put him and his men beyond the norms of warfare. According to the "History of Shelby County," which is generally sympathetic to Porter, "Most conceded that Col. Porter's purpose for capturing Memphis, MO. was to seize Dr. Wm. Aylward, a prominent Union man of the community." Aylward was captured during the day by Captain Tom Stacy's men and confined to a house. After rousing him overnight and removing him, ostensibly to see Porter, guards claimed that he escaped. However, witnesses reported hearing the sounds of a strangling, and his body was found the next day, with marks consistent with hanging or strangulation.^[1]

At Memphis, Porter had been joined by Tom Stacy, generally regarded as a genuine bushwhacker – even the sympathetic Mudd says of him "if one of his men were captured and killed he murdered the man who did it if he could catch him, or, failing him, the nearest man he could catch to the one who did it."^[2] Stacy's company was called "the chain gang" by the other members of Porter's command. Supporters of Porter attribute the murder of Aylward to Stacy (who would be mortally wounded at Vassar Hill.) However, a Union gentleman who came to inquire about Aylward and a captured officer before the discovery of the body stated that when he asked Porter about Aylward, the response was, "He is where he will never disturb anybody else."^[3]

Vassar Hill

Union Col. (later General) John McNeil pursued Porter, who planned an ambush with perhaps 125 men according to participant Mudd ^[4] (though Federal estimates of Porter's strength ran from 400 to 600 men). The battle is called "Vassar Hill" in the History of Scotland County; Porter himself called it "Oak Ridge," and Federal forces called it "Pierce's Mill," after a location 1.5 miles northwest of the battlefield. A detachment of three companies (C, H, I),^[5] about 300 men of Merrill's Horse,^[6] under Major John Y. Clopper, was dispatched by McNeil from Newark against Porter, and attacked him at 2 p.m. on Friday, July 18, on the south fork of the Middle Fabius River, ten miles southwest of Memphis. Porter's men were concealed in brush and stayed low when the Federals stopped to fire prior to each charge. Porter's men held their fire until the range was very short, increasing the lethality of the volley.^[7] Clopper was in the Federal front, and out of 21 men of his advance guard, all but one were killed and wounded.^[8] The Federals made at least seven mounted charges according to Mudd, doing little but adding to the body count. A battalion of roughly 100 men ^[9] of the 11th Missouri State Militia Cavalry under Major Rogers arrived and dismounted. While Clopper claimed to have driven the enemy from the field after this, Mudd indicates that the Federals instead fell back and ended the engagement leaving Porter in possession of the field until he withdrew. Clopper's reputation suffered as a result of his poor tactics. Before the final charge one company officer angrily asked, "Why don't you dismount those men and stop murdering them?" ^[10]

On page 86 of "With Porter in North Missouri", Mudd describes "One of our boys, down the line out of my sight, losing his head fired too soon and when the Federal was about to ride him down, had an empty gun in his hand. This he clubbed and striking his assailant a powerful blow on the neck, killed him." In Joseph Budd's pension records, his death is described as occurring due to "a stroke of a weapon breaking his neck". Joseph is pictured on the right.

Union casualties were about 24 killed and mortally wounded (10 from Merrill's Horse and 14 from the 11th MSM Cavalry), and perhaps 59 wounded (24 from Merrill's Horse, and 35 from the 11th MSM Cavalry.) Porter's loss was as little as three killed and five wounded according to Mudd, or six killed, three mortally wounded, and 10 wounded left on the field according to the Shelby County History.^[11] The Union dead were originally buried on the Jacob Maggard farm, which served as a temporary hospital.^[12]

After the fight, Porter moved westward a few miles, then south through Paulville, in the eastern part of Adair County; thence south-east into Knox County, passing through Novelty, four miles east of Locust Hill, at noon on Saturday, July 19, having fought a battle and made a march of sixty-five miles in less than twenty-four hours.^[13]

Florida

July 22: Detachments of F & G Companies (60 men total) of 3rd Iowa Volunteer Cavalry under Major Henry Clay Caldwell encountered Porter with 300 rebels at Florida in Monroe County, Missouri. The detachment fought outnumbered for one hour and fell back upon the post of Paris, Missouri, with 22 wounded and 2 captured.

Santa Fe

July 24: Major Caldwell and 100 men of his 3rd Iowa Volunteer Cavalry pursued Porter and his 400 men into dense brush near Botts' farm, near Santa Fe, Missouri. Porter fled and was pursued into Callaway County, Missouri. The Second Battalion suffered one killed and ten wounded.

Moore's Mill

July 28: Union forces under Colonel (later General ) Odon Guitar engaged Porter near Moore's Mill (now the village of Calwood) in Callaway County. The Union losses were 19 killed, 21 wounded. Guerrilla losses were 36-60 killed, 100 wounded. This was one of Porter's most aggressive actions, involving a daring charge and disabling the Federal artillery, until forced to retreat by the arrival of Union reinforcements and the exhaustion of his ammunition.

Newark

August 1: McNeil had dispatched Lair to Newark. Porter headed westward from Midway, putting his brother Jim Porter in charge of one column, himself at the head of another, approaching the town from east and south simultaneously, and closing the trap on the completely surprised federals at 5 p.m. on July 31.

Porter forced a company of 75 Federals to take refuge in a brick schoolhouse; when they refused terms, he had a loaded haywagon fired and threatened to run it into the building. The Federals surrendered, were paroled and permitted to keep their sidearms.

The Federal loss in the Newark fight was 4 killed, 6 wounded, and 72 prisoners. The Confederate loss was reported at from 10 to 20 killed, and 30 severely wounded. Union soldiers were treated well, but the Union-sympathizing storekeepers had their businesses gutted, and citizens were subjected to abuse. Some claim this was in spite of Porter's orders, and claimed that he bore his old neighbors no malice, while others view this action as Porter's revenge for previous ill-treatment.

Despite the victory at Newark, the high casualties on the winning side, attributed to chaotic advance and undisciplined exposure of Porter's troops to hostile fire, suggest growing disorder in his ranks. From here, records of his activities—and even the degree to which he can be said to have a unified command—are unclear. Various forces with varying degrees of official relation to Porter's command are credited with capturing Paris and Canton, and with bringing in new supplies and recruits. Porter's numbers had swelled to a size likely to be unmanageable, particularly considering the lack of trained officers and that not more than a quarter of his 2000 or so troops had regulation equipment. Perhaps another quarter had squirrel-guns or shotguns, while the rest no arms at all. Porter's objective was now to get south to Arkansas with his recruits, in order that they might be properly trained and equipped.

Kirksville

Union Colonel John McNeil, who defeated Porter at the Battle of Kirksville.

August 6, 1862

At Kirksville, Porter made a serious mistake in engaging Union forces under Col. John McNeil, whom he knew to have cannon – perhaps in overconfidence, as a result of his sharpshooters' ability to pick off the Federal artillerymen at Santa Fe. Traveling light had been Porter's great advantage -- "His troops lived off the country, and every man was his own quartermaster and commissary," in contrast to the elaborate baggage and supply trains of McNeil ("History of Shelby County"). Here Porter suffered unequivocal defeat, from which he would not recover.^[14]

Dispersal of forces

At Clem's Mills, five miles west of Kirksville, Porter crossed the Chariton River, seeking to link up with Col. John A. Poindexter in Chariton County, known to have 1,200 or 1,500 recruits; their combined forces would be able to force a passage of the Missouri River at Glasgow or Brunswick, and open a line to the Confederacy. Three miles north of Stockton (now New Cambria), in western Macon County, Porter encountered 250 men of the First Missouri State Militia, under Lieut. Col. Alexander Woolfolk, coming up to unite with McNeil. There was a brief fight at Panther Creek, Friday, August 8. Porter was turned from his course and retreated toward the northeast, away from his intended line of march and ultimate goal. The next day, Col. James McFerran, of the First Missouri State Militia, joined Woolfolk with 250 more men and took command. He caught up with Porter at Walnut Creek, in Adair County and drove him eastward to the Chariton. At See's Ford, where he recrossed the Chariton, Porter set up an ambush on the east bank with 125 men. Porter's forces opened fire at short range. Only two Federals were killed outright and 15 wounded, but the action seemed to have caused McFerran to break off pursuit.

Porter passed on to Wilsonville, in the south-east part of Adair. Here, a mass desertion took place among his discouraged troops; in a few hours, 500 had drifted away.

Capture of Palmyra and the Allsman incident

Porter wandered around the wilderness, his desertion-diminished troops feeding off the land, although there were some new recruits as well. On Friday, September 12, Porter, with 400 men, captured Palmyra, with 20 of its garrison, and held the place two hours, losing one man killed and one wounded. One Union citizen was killed and three Federals wounded. Porter's objectives were to liberate Confederates held in the jail there, and to draw Federal forces away from the Missouri River, so as to open it to southward crossing by rebels seeking to join Confederate units.

The Confederates carried away an elderly Union citizen named Andrew Allsman. The fate of Allsman remains something of a mystery, and there is disagreement as well about his character and his legitimacy as a target (see Palmyra Massacre).

Porter quickly abandoned Palmyra to McNeil, and another period of wandering ensued, in the general direction of his own home near Newark. There were further desertions, and a number of bands of organized rebels refused to place themselves under Porter's command, clearly indicating that he had lost public confidence. At Whaley's Mill, his men were definitively scattered, almost without a fight.

Death

After his rout by McNeil at Whaley's Mill, and the dispersion of his troops at Bragg's school house, Col. Porter kept himself hidden for a few days. He abandoned the idea of raising a militarily significant force, and entered Shelby County on a line of march to the south with fewer than 100 men remaining. He made his way safely through Monroe, Audrain, Callaway and Boone counties, and crossed the Missouri River in a skiff, continuing into Arkansas. Here he organized, from the men who had accompanied him and others whom he found in Arkansas, a regiment of Missouri Confederate cavalry. From Pocahontas, Arkansas, in the latter part of December 1862, as acting brigadier, he moved with his command and the battalions of Cols. Colton Greene and J. Q. A. Burbridge, to cooperate with Gen. John S. Marmaduke in his attack on Springfield. Through a mistake of Gen. Marmaduke, Col. Porter's command did not participate in this attack. It moved on a line far to the east. After the expedition had failed, the commands of Marmaduke and Porter united east of Marshfield, and started to retreat into Arkansas.

At the Battle of Hartville, in Wright Country on January 11, 1863, a small Federal force was encountered and defeated, although at severe loss to the Confederates, who had many valuable officers killed and mortally wounded. Among the latter was Colonel Porter,^[15] commanding a brigade, shot from his horse with wounds to the leg from an artillery shell. In Oates's account, (118-119), Porter died an hour later. According to Mudd, however, Porter was shot from his horse with wounds to the leg and the hand while leading a charge; in this account, Porter managed to accompany the army on a difficult trek into Arkansas, arriving at Camp Sallado on January 20, and at Batesville January 25, where he died from his wounds on February 18, 1863. The early date is refuted by Porter's own report, dated February 3,^[16] referencing the journey after the battle, as well as eyewitness Major G.W.C. Bennett's reference^[17] to "Porter's column" on the march several days after and dozens of miles away from the battle, and finally by Marmaduke's noting Porter among the wounded,^[18][19] in contrast to the listing of officers killed; additional near-contemporary sources also affirm Porter's survival of the journey to Arkansas.^{[20][21][22][23][24]} The January 11 date seems to originate with General Fitz Henry Warren, who reported as fact^[25] the speculation that a burial observed by a recently paroled Lieutenant Brown^[26] was that of Porter.

The location of Col. Porter's grave remains unknown. Oral traditions suggest that he was at some point buried on the farm of his cousin Ezekiel Porter (said to be a volunteer ambulance driver during the war), just north of Hartville, in what is now known as Porter's Cemetery, near Competition, Missouri.
