Lorenzo De Medrano Y Treviño

Lorenzo de Medrano y Treviño (August 10, 1787 – April 11, 1854) was a noble from the House of Medrano, the Spanish Lieutenant Colonel of Engineers, the sole representative of the Spanish Military Corps of Engineers, artilleryman, and brigade sergeant major of the coast of Granada, notable for his extensive military service during the Peninsular War. Medrano played critical roles in several key battles and military engagements, including the defense of the Júcar River crossing, the Battle of the Fields of Tudela, and the sieges of Morella and Sagunto castles. He was particularly distinguished during the "Escape of the Sappers" at the outset of the Peninsular War, leading troops from Alcalá de Henares to Valencia. Lorenzo was the younger brother of the important military leader and liberal politician Diego de Medrano y Treviño.

Family

Don Lorenzo de Medrano was the son of José de Medrano y Monroy, baptized in Almagro on 31 March 1748. Lord of all the majorats, entailments, and patronages of the family, José de Medrano y Monroy married the VI Lady of the Majorat of Valdarachas, Doña Isabel de Treviño y Treviño. Through this marriage, Don José de Medrano became a resident of Ciudad Real. The wedding took place in the town of Miguelturra, four kilometers from Ciudad Real on the road to Almagro, on 16 February 1776. Don José de Medrano significantly increased and improved his and his wife's assets, as evidenced in the family archive, finally making his will in Ciudad Real on 30 September 1800. His wife, the VI Lady of the Majorat of Valdarachas, made hers in the same city on 10 August 1787.

Ecclesiastical patronage

Lorenzo belongs to the ancient and noble House of Medrano, one of the most powerful in the Sierra de Cameros and in Soria within the Kingdom of Castile. Lorenzo de Medrano and his family are generational patrons of the Franciscan Order. In approximately 1211, a captain of the Medrano family held the lordship of the castle and town of Agoncillo, situated near the city of Logroño, in the region of La Rioja, a territory under the Kingdom of Navarre and in 1276, the Kingdom of Castile. Medrano's son was suffering from a mysterious and untreatable ailment. In 1211, Saint Francis of Assisi roamed those very paths of Agoncillo. In a saintly manner, he visited Medrano's Agoncillo castle, placed his mystical hands upon the ailing Medrano boy, and miraculously healed him, securing the Medrano lineage in Agoncillo. As a result, the Medrano family are distinguished by their devotion to Saint Francis of Assisi and their generational patronage of the Franciscan order.Recoge esta historia, entre otros, D. Cesáreo Goicoechea en "Castillos de la Rioja, Logroño, 1949, y Fray Domingo Hernáez de Torres en "Primera parte de la Crónica · ranciscanade la Provincia de Burgos". Madrid, 1772. The Medrano family generously donated some land, including a tower, situated close to the Ebro River within the city of Logroño as a gift to Saint Francis, establishing the first Spanish convent of his Order there. Unfortunately, despite its centuries-long legacy of glory and sanctity, the convent met its demise in the 19th century due to the advent of liberalism and its accompanying laws. Today, the remnants of its walls still remain.

Heraldic legacy and evolution

The House of Medrano—to which Lorenzo belonged—developed a complex heraldic identity reflecting the family’s military achievements, legal authority, and dynastic alliances over centuries. The evolution of their coat of arms traces a deep continuity between the family’s martial service, proximity to royal power, and their contributions to the political structures of Spain and Navarre. According to the Revista Hidalguía and other genealogical records, the arms originated in Navarre (12th–13th centuries) with the early Lords of Igúzquiza, Agoncillo, and Valdeosera.

The first devices featured simple martial crosses symbolizing battlefield valor. At the Battle of Las Navas de Tolosa (1212), the Medranos were awarded the right to bear the Cross of Calatrava—an Or cross fleury on a gules field—augmented with an azure border containing eight Or saltires (crosses of Saint Andrew). This augmentation marked the family's heroic contribution to one of medieval Europe’s most significant victories. Later, at the Battle of Río Salado (1340), the family standard prominently featured these saltires, which became enduring symbols of military honor and augmentation.

Alliance between the Houses of Medrano and Zúñiga

In the 16th century, the Manchegan branch (Ciudad Real) emerged when Juan Valeriana de Medrano y Herruz married Mariana de Zúñiga y Oviedo, heiress of the Zúñiga majorats (''mayorazgos''). This marriage brought lordships, hereditary rights and majorats associated with the House of Zúñiga into the House of Medrano and introduced the Zúñiga sable bend into the Medrano arms, symbolizing a strategic alliance with one of Castile's most powerful noble houses.

Heraldry

This composite design appears in both the arms of the Manchegan branch and in the insignia used by Tomás Fernández de Medrano in his ''República Mista'' (1602), where the heraldic imagery also served as a visual code for the legal and political doctrine of '' medrar''—noble advancement through service, counsel, and delegated power.Campos-Perales, Àngel. “''Los validos valencianos del valido: arte y legitimación social en tiempos del Duque de Lerma (1599–1625)''.” Espacio, Tiempo y Forma. Serie VII: Historia del Arte, no. 12 (2024): 275–296. https://doi.org/10.5944/etfvii.12.2024.38583.

By the 17th century, the family's heraldry had crystallized into a complex emblem combining:

* The Hollow Cross of Calatrava insert Or

* The eight saltires of Saint Andrew

* The Zúñiga sable- bend

Lords of Valdarachas and patrons of the Franciscan Convent in Almagro

During the 18th and 19th centuries, Lorenzo's immediate ancestors—particularly his grandfather Francisco de Medrano y de León Peralta y Córdoba—maintained these composite arms, integrating their status as lords of Valdarachas and patrons of the Franciscan convent in Almagro. This patronage was not incidental but continued the Medrano family's generational alliance with the Franciscan Order, which had begun in 1211 when Saint Francis himself healed the Medrano heir at Agoncillo, leading to the founding of Spain's first Franciscan convent in Logroño. The chapel within the Franciscan convent in Logroño was commissioned and funded by Diego López de Medrano, Lord of Agoncillo, and served as the family mausoleum. The family’s heraldry, ecclesiastical patronage, and military service intertwined their identity with both sacred and secular authority.

Family legacy

Lorenzo's own military career as the sole representative of the Corps of Engineers and his brother Diego’s political leadership continued this legacy of service. The family arms, preserved through the Manchegan branch, reflected not only their noble status but the cumulative ''grammar of medrar'' that had defined the Medranos from the ''Reconquista'' through the Napoleonic era.

Education and military career

Don Lorenzo de Medrano was the Captain, Chief, and Lieutenant Colonel of Engineers and the sole representative of the Spanish Military Corps of Engineers in the Spanish Empire during the 19th century, ensuring the military legacy of his family.

The Spanish Military corps of Engineers has its origin in the teachings of the first modern and Royal Military and Mathematics Academy of Brussels in Europe, established in 1675 and directed by Sebastian Fernández de Medrano, the Master of Mathematics of the Kingdom, military engineer and General of the Artillery (under the Marquess and Governor Captain General Francisco Antonio de Agurto Salcedo Medrano Zúñiga) at the request of Carlos de Aragón de Gurrea, 9th Duke of Villahermosa.

When Sebastian's disciple Lieutenant General Jorge Próspero de Verboom was appointed Chief Engineer on January 13, 1710, and tasked with establishing and organizing the Corps of Engineers, one of his first thoughts was the creation of Military Academies using the same curriculum as his mentor's. Verboom proposed Military Academies in Oran, Cueta and Barcelona, all three were established.

Education

Don Lorenzo de Medrano's military career commenced in July 1802 when he joined as a cadet in the Provincial Regiment of Ciudad Real. Self-taught in mathematics, he advanced to the Corps of Engineers as a second lieutenant on July 13, 1803, and subsequently pursued further studies at the Engineering Academy of Alcalá de Henares.

Early military career

Upon completing his studies, he was promoted to lieutenant on February 25, 1806, and assigned to the Corps' Sub-inspection Directorate in Valencia.

Enlisting in the army

When news of the May 2, 1808 uprising in Madrid reached Valencia, Lorenzo joined the army formed there, serving until September 1809 before transferring to command a Sappers' Company in the Army of Catalonia.

Escape of the Sappers (1808)

During the early stages of the Peninsular War, an incident known as the "Escape of the Sappers" occurred. It involved a mass departure of officers and troops from the Engineering Academy in Alcalá de Henares to Valencia to join forces rebelling against the French occupation. After enduring difficult marches and constant threats from French forces, they arrived in Cuarte on June 5. Sergeant Major Veguer arrived on June 7 and dispatched Second Lieutenant Manzanares with a letter to the captain general, following advice from Lieutenant "D. Lorenzo Medrano." Upon visiting the Count of Cervellón, they were instructed to surrender their weapons as other garrisons had. However, Upon hearing the troops should surrender their weapons, Lieutenant Lorenzo de Medrano declared they would "perish a thousand times with them rather than surrender."J. A. Ferrándiz, “El Real Cuerpo de Ingenieros del Ejército en la Guerra de la Independencia: Valencia y Murcia A cross was awarded for their bravery.

Battle of the fields of Tudela

Medrano later played a key role in the defense and subsequent pursuit of the enemy at the Júcar River crossing, and fought at the Battle of the Fields of Tudela in November 1808. Following a grueling retreat to Cuenca, he returned to Valencia.

Regional fortification of Cuenca

The Segorbe town council later sought Don Lorenzo de Medrano's expertise for regional fortification in Cuenca, requesting:

"an agreement on the fortification of the area and commissioning of Engineer Captain Lorenzo Medrano to oversee the works."

Army of Catalonia

In 1809 Don Lorenzo de Medrano was assigned a Sapper company in the Army of Catalonia. In his role with the Army of Catalonia, he aided in the relief of Girona and the retreat from Albentosa to Valencia. Lorenzo's brother Don José de Medrano y Treviño was also a combatant in the Peninsular War as an artilleryman, participating in the siege of Girona and the defense of Montjuich in Barcelona, where his heroism earned him a promotion to captain. His brother Don José de Medrano authored a manuscript about the siege of Girona.

As Commander of Engineers of the Vanguard Division in early 1810, Lorenzo de Medrano faced the French forces of Napoleon near Valencia. He was also active in 1810 around Morella and during the siege of its castle, and aided in the relief of the fortress of Tortosa. In May 1811, he marched with his division from Peñíscola to aid the fortress of Tarragona.

Captain and the sole representative of the Corps of Engineers

He was involved in the retreat from the kingdom of Aragon to Valencia and in the defense of the castle of Murviedro (Valencia). Lorenzo de Medrano participated, as captain and the sole representative of the Corps of Engineers, in the defense of the castle of Sagunto. Specifically, during the defense of Sagunto castle from September 23 to October 26, 1811, he was noted for his command alongside sapper Villalta:

"The Chief of Engineers Captain D. Lorenzo Medrano, and the sapper Villalta, along with other commanders and troops of other Arms were distinguished."

He skillfully managed the breach repairs, with the governor later commending the defenders for their "amazing bravery," and recognizing their efforts with awards. He was made a prisoner by the French when the fortress surrendered.

Rise in ranks and retirement

After the war, Medrano was justified for his military and political actions and assigned to Granada's coast as a brigade sergeant major in September 1815, having been promoted to lieutenant colonel of Engineers earlier that month. He served in the Command of the Corps in Navarre until 1821, when he retired to Ciudad Real. He died on April 11, 1854.

Marriage and children

Don Lorenzo de Medrano y Treviño was the husband of Doña María de Morales, and father of Don José de Medrano y Morales, Doña Carmen, and Doña Manuela de Medrano y Morales.

Ancestry

Don Lorenzo de Medrano y Treviño was the paternal great-great-great-grandson of Don Juan Valeriana de Medrano y Herruz. In the city of Almagro, in La Mancha, upon marrying into and inheriting the lordships and representations of the House of Zúñiga, Don Juan Valeriana de Medrano y Herruz from La Mancha added the well-known sable band of Zúñiga to the shield of the Medrano family.

Don Juan Valeriana de Medrano y Herruz was the son of Don Juan de la Cámara de Medrano and Doña Antonia de Herruz y Vergara and the paternal grandson of Don Sancho González de Almazán, of the Medrano lineage, a resident of the town of Garray, in Soria, around the year 1480. Don Juan Valeriana was baptized in the town of Arenas on 14 April 1599, with his aunt and godparents Doña Catalina de Medrano and her husband, licentiate Avila de Alarcón. He married Doña Mariana de Zúñiga y Oviedo in Almagro on 3 September 1626. Don Juan Valeriana de Medrano made his will in Almagro on 29 November 1649, and his wife, Doña Mariana de Zúñiga, in the same place on 21 January 1675.

Don Lorenzo's great-great-great-grandmother Doña Mariana de Zúñiga was the daughter of Don Bernardo de Oviedo and Doña Bernarda de Zúñiga, the Lady of the Majorat of Esparragués, established by her third great-grandfather, Don García de Pisa, through his will in 1484. She also belonged to the patronage of Almagro, initiated by Don Crstóbal de Oviedo (her great-uncle) through his will signed in Madrid on 3 April 1590. This connection brought additional lands and the Zúñigas' sable band to the Medrano family shield in Almagro.

Great-great grandfather

Don Lorenzo is the paternal great-great-grandson of Don Juan Manuel de Medrano y Zúñiga, born in Almagro on 17 June 1627. His great-great-grandfather served as a Familiar of the Holy Office and held prominent roles including Perpetual Alderman, and later the Mayorship and the Alderman of the Holy Brotherhood by the Noble Estate in Almagro.Archivo de Medrano Trevifio. Leg. G, núms. 92 y 94 Juan Manuel de Medrano y Zúñiga married Doña María de Peralta y Reinoso, a native of Almagro born on 12 December 1629, on 6 November 1652. Doña María was deeply rooted in local nobility; she was the daughter of Don Juan Ossorio de Peralta, the fourth blood patron of Almagro's Franciscan convent and a Perpetual Alderman, and Doña Jerónima Gutiérrez de Guevara. Her lineage included several patrons of the same Franciscan convent, with her great-great-grandparents establishing their noble status in Illescas in 1585. Her great-granduncle, Don Jerónimo Dávila de la Cueva, founded the Franciscan convent in Almagro in 1597.

Restoration efforts began in the 20th century under the patronage of the Medrano family. The mother of the beforementioned Doña María de Peralta y Reinoso was Doña Jerónima Gutiérrez de Guevara, daughter of Don Tomás Gutiérrez de Guevara, who made his will in the City of Saña, in the kingdom of Peru, on 23 May 1634, and Doña Francisca del Salto, sister of the latter and heiress of Don Andrés del Salto y Manzanares, who is the founder of the Majorat of Cervera by his will signed in Almagro on 17 August 1619, thus bringing the Majorat of Cervera and the patronages of San Bartolomé to the Medrano family.

Great grandfather

Don Lorenzo is the paternal great-grandson of Don Carlos-García de Medrano y Peralta, 8th generation of his name and eldest of the House of Medrano in Almagro due to the death without succession of his elder brother Don Juan de Medrano y Peralta, resident of Arenas, thereby becoming the possessor of the Majorats of Esparragués, Cervera, and other lands in Arenas, Illescas, and Almagro, patron of the Franciscan convent in Almagro and of the chapel of San Bartolomé in Almagro.
