These are excerpts from my book on Filibuster operations. here are three battles of the campaign.
Battle of ROSILLA (or Salado Creek) , March 1813.
The Republican Army consisted of eight hundred Anglo under Colonel Kemper; one hundred and eighty Mexicans from Nacogdoches under Colonel James Gaines and Manchaca plus another three hundred and twenty-five Indians. The Republicans began their advance in their deployment order for the battle. The left wing was under the command of Major Ross who placed himself in the lead element. The right wing was under Colonel Kemper who placed himself in the rear to better observe the entire command. A company of marksmen armed with rifles were deployed along the flank of the right wing. The riflemen were commanded by Captain Luckett. The American left wing was secured by the San Antonio River, along the bank of which they marched.
The Royalist had established positions along a ridge which separated the Salado and San Antonio Rivers. The road along which the Republicans advanced ran between the ridge and the San Antonio River. The slope of the ridge that faced the San Antonio River was relatively clear but as you neared the crest thick chaparral dotted the top. On the Salado side of the ridge the chaparral was more dominant. It was among the protective chaparral that the Royalist deployed their forces in hope of an ambush. The Royalist positions stretched for three quarters of a mile and contained twelve pieces of artillery.
The flanking company of riflemen did their duty and spotted the Royalist and immediately initiated combat and warned the main body of the Republican army.
The Royalist returned fire and engaged the Republicans who were still four hundred yards distant.
The Indian warriors had been deployed in the vanguard to absorb initial casualties and lessen the impact of an expected Royalist cavalry charge. The Royalist volleys caused many of the Indian warriors to break ranks and seek shelter. The Cooshatties tribe and a few others held their ground and repulsed Royalist probing attacks.
The stand by the Indians and the flanking riflemen had allowed the main body of the Republican had formed at the foot of the ridge. A pre-determined tactic had been arranged for the Republicans to advance to within thirty yards of the Royalist line and fire three rounds. After loading a fourth round, the Republicans would then charge along the whole line. The pre-arranged tactic was followed without a mistake and worked. While the Republicans advanced uphill, most of the Royalist volleys were fired too high and inflicted little damage upon the exposed Republicans.
As the Republicans closed with the Royalist positions, most of the Royalist retreated rather than face the assault. Colonel Herrera was killed among the guns while he tried to fight hand to hand with first major Ross and then Colonel Kemper. The Royalist lost many troops during the rout as the Indians swept among their fleeing ranks. This resulted in the killed being disproportionate to the captured with an estimated one thousand casualties being suffered by the Royalist.
The next day the Americans pursued their march to the borders of the town of San Antonio, Governor Salcedo was faced with an undependable position and surrendered his command. A large body of Royalist troops along with military stores, arms, and pay chests were all surrendered. The spoils were distributed to every soldier in the force. The Indians received a smaller share including presents and were dismissed from service.
Royalist numbers were listed by some sources as few as six hundred men with those same sources listing the Republican forces as three hundred men. Based upon some reports which list Republican forces as closer to thirteen hundred and the losses, the Royalist Army could have numbered between three thousand and four thousand men.
The Royalist prisoners were freed with some joining the Republicans, and other simply returning home. Salcedo and his staff were permitted a limited amount of freedom but were soon executed by the Creole General Bernardo Gutierres. Upset by the executions the main Anglo officers including Colonel Kemper, Major Ross, and others, left the army and returned home. However the news of the victory in Texas encouraged other Anglos to join the effort.
Battle of Alazan, June 4-5, 1813
A new Royalist army was gathered and dispatched by the viceroy. It was commanded by Don Elisondo, who betrayed Hidalgo to the Royalists. The Royalist army consisted of about fifteen hundred regulars, and another fifteen hundred volunteers from the heavily Royalist internal provinces. Of the American officers who remained, Captain Perry was highest in rank, and in operational command of the mostly Anglo force with General Gutierres acting as a co-commander for morale reasons.
Elisondo halted his advance and established camp about half a mile from the town's graveyard. The Royalist reinforced their position by building two bastions at each end of their position. This placed them about four hundred yards apart. . This hasty emplacement was placed on top of the ridge's summit which sloped gently down to the Alazan River, a branch of the San Pedro, behind which the Republicans were encamped.
The Republicans fearing a hasty retreat spiked all the artillery that they could not effectively man except four small field cannon. The Republicans then conducted a silent night march late on the night of June 4th. They assumed initial deployment positions as close to the Spanish fortifications as possible.
Once the signal was given the Republicans quickly captured the defensive positions without much trouble. They lowered the Spanish flag and raised the tricolor flag that they had been using in San Antonio. At dawn the situation became clear to the Royalist who launched a ferocious counterattack from their main camp. The Royalist charge regained all of the lost ground in the fortifications.
The Republicans rallied to assault the emplacements. For a second time, they captured the fortifications and advanced toward the main Royalist positions in the camp. By now the limited amount of ammunition with which the Republicans had started had been depleted. As a result the fight progressed with them using mainly the bayonet, knives and spears. The fight proved to be a long an bitter struggle. After several hours, the Royalist had been forced into positions which were hard to defend and they broke ranks and fled.
The Royalist casualties were estimated at a thousand dead, wounded, and prisoners. While the Republicans reported only forty-seven killed, many of the wounded died of their wounds. The Royalist fled to the Rio Grande before they regrouped. The Republicans returned to San Antonio and relieved General Gutierres who returned to the Natchitoches area.
Battle of MEDINA, 18 August 1813
Don Jose Toledo was a Creole from a distinguished Spanish family. He had formerly been a member of the Spanish Cortes in Mexico, but was banished on account of his Republican sympathies. He had been forwarding recruits and supplies from Louisiana to San Antonio. In July, 1813, he set out for San Antonio. He was welcomed with much ceremony, and immediately elected commander-in-chief of the Republican army of the North.
General Arredondo, commandant of the northeastern provinces combined his troops with any of Elisondo's army which he could rally. His command numbered nearly two thousand men according to Royalist reports but almost four thousand men according to the few Republican accounts of the battle. Once he reached the Medina River, Arredondo constructed a V shaped breastwork. The apex of the breastwork as set the road, and the open end in the direction of San Antonio. Six hundred troops were deployed in the upper part of the open V at about four hundred yards in front of the breastwork. The breastwork was concealed by an artificial chaparral to appear as natural growth. It contained the bulk of the Royalist Army.
Toledo advanced to engage the Royalist force. His force by this time had been reorganized according to the Spanish tradition of ethnic units with companies of Americans (Anglos), Indians and Mexican (Creoles). The force totaled 1,550 men and consisted of eight hundred and fifty Anglos, under Perry and about seventeen hundred Mexicans commanded by Manchaca. Manchaca was regarded by some to have been insubordinate toward Toledo during the battle due to being passed over for Command of the Army. Toledo placed his trust on his Mexican troops and weakened the American contingent by dividing them on the two wings, with the Mexicans deployed in the center.
The exposed Advance Guard of the Royalists fired an initial round of artillery and musketry. At this point they withdrew into the breastworks and assumed new firing positions. The Mexican command holding the center rushed forward to pursue what they thought was the retreating main body of the Royalist. The center ground lacked any obstacles and soon the Mexicans out-raced the Anglos holding each wing. As the Anglos became tied up with fortifications facing them, the Mexicans continued to advance until they were exposed and receiving musketry and artillery fire to the front and on both flanks.
Once Toledo saw the trap, he ordered a retreat with only the Left wing following the orders. The Right Wing refused to admit defeat and continued to fight. As a result the entire Republican Army was destroyed in piecemeal by the Royalist. The Anglos on the right made several assaults on the breastworks but were repulsed on each attempt. Only the Anglos of the left Wing and a few Mexicans of the reserve center were able to get away from the field of battle.
The fugitives continued their retreat with the Royalist cavalry in close pursuit. At Spanish Bluff, on the Trinity River, the enemy took seventy or eighty prisoners which were soon executed. Only ninety-three Americans succeeded in reaching Natchitoches. Among them were Colonel Perry, Captain Joseph Taylor (badly wounded), and Captain Bullard, who had acted as aid to Toledo during the battle.
Two days after the battle of the Medina, which was fought on the 18th of August, 1813, General Arredondo marched in triumph into San Antonio and imprisoned both sympathizers and less ardent supporters of the Crown. Many died or were executed during the captivity. The property of the Republican supporters was confiscated. This ended the filibuster effort of 1812 and 1813.
Between 1813 and the Texas Revolution, several filibuster attempts were made by different adventurers and organizations. While the levels of success for these different groups varied, one of these attempts led to a serious battle. The Texas Revolution and their period of Independence as a Republic are treated as a separate issue from filibuster operations.
