Durrës Expedition

The Durrës Expedition (Ekspedita e Durresit) was an invasion of the Principality of Albania, led by Karl Thopia, by the Navarrese Company, under the command of Louis of Évreux. Louis hired the Navarrese Company to support him in reclaiming his newly acquired rights over the city of Durrës and the Kingdom of Albania, inherited through his marriage to Joanna, Duchess of Durazzo. While details of the expedition are scarce, Louis succeeded in occupying Durrës and ousting Karl Thopia in 1376. However, he died shortly thereafter, rendering his contract with the Navarrese Company void. The mercenaries relocated to Morea under new leadership, leaving Durrës a contested city until another invasion by Karl Thopia in 1383, which led to the final disestablishment of the Kingdom of Albania.

Background
Joanna, Duchess of Durazzo, inherited the rights to the Kingdom of Albania upon her father Charles, Duke of Durazzo's death, and subsequently ruled as a duchess. In 1365 Louis of Évreux married Joanna and inherited the rights to the Kingdom of Albania, becoming the Duke of Durazzo by right of his wife. Karl Thopia from the Albanian Thopia family conquered and took control of Durrës in 1368 and incorporated it into the Principality of Albania. Durrës had been the last stronghold of the Angevins, who maintained control over the kingdom, until Karl Thopia conquered the city, leading to the disestablishment of the Kingdom of Albania. After this event, Louis made various attempts to expel the intruders from Durrës and Albania as a whole. However, detailed records of these attempts have been lost over time, leaving little documentation of his early efforts.

Expedition
The final effort by Louis of Évreux to assert his claim to the Kingdom of Albania and restore its rule began in the early 1370s. In 1372, the ranks of the a group of mercenaries from Navarre, known as the Navarrese Company, began to swell at the behest Enguerrand VII de Coucy, who orchestrated the recruitment of 500 lances and 500 mounted archers from Gascony. These troops were assembled to support the campaign to conquer the Kingdom of Albania. Louis also enlisted four companies of knights from Navarre to support his claim by 1376. The majority of the soldiers in the Navarrese Company, recruited mainly between 1375 and 1376, came from Navarre and Gascony. They received a monthly payment of thirty florins of Aragon, with the enrolment lists preserved in the Archives of the Cámara de Comptos in Pampeluna.

The soldiers from Navarre and Gascony made extensive preparations for the invasion of Albania. However, scant information is available regarding the Albanian expedition overall. Louis garnered substantial martial support in the form of men-at-arms from his brother Charles II, the King of Navarre, and monetary support amounting to 50,000 ducats from Charles V, the King of France. The Navarrese Company was led by four individuals: Pedro de la Saga and Mahiot de Coquerel, both chamberlains of the Navarrese king; John de Urtubia; and Garro (or Guarro), who is documented as a squire. The battle for the city began in the midsummer of 1376, and Louis and the Navarrese Company were successful in occupying Durrës, which officially reestablished the Kingdom of Albania.

Aftermath
Louis of Évreux died in 1376, the same year he succeeded in gaining back Durrës and reestablishing the Kingdom of Albania. With Louis's death, the Navarrese Company's contract was terminated. They possibly continued to serve Joanna of Durazzo until her remarriage. Marooned and keen to return to Navarre and Gascony, the Navarrese Company endured between two and three demanding years in destitute Durrës before eventually moving to Morea. There, they entered the service of Jacques de Baux, Nerio Acciajuoli, Juan Fernández de Heredia, and Peter IV of Aragon  Durrës remained under the control of Joanna and her second husband Robert IV of Artois for a few years until Karl Thopia invaded again in 1383, leading to the final disestablishment of the Kingdom of Albania.
