Battle of the Counts

On 16 April, the first fleet of 40 Angevin galleys put to sea from Apulia, led by Reynald III of Avella. Striking first at Malta (possibly a feint to distract the Aragonese), the Angevin fleet then sailed to and captured the town of Augusta on Sicily. The town was taken almost without resistance, emboldening the Angevins to march north to Catania, which they besieged. The town was relieved by an Aragonese-Sicilian army, and Lauria sailed his fleet of 40 galleys to retake Augusta, but the Angevin fleet was able to evade him.[1] While the Aragonese were forced to besiege Augusta, the Angevin fleet sailed to attack the poorly-defended western coast of Sicily. While King James II of Sicily wanted Lauria's fleet to support his siege of Augusta, the admiral disagreed and sailed his fleet in pursuit of Reynald.[1] The Angevin fleet raided a few towns in western Sicily, circumnavigated the island, and linked up with the Angevin fleet in Campania; thus, the Aragonese faced a force of over 80 galleys against their 40.[1] Confronted with the large Angevin force now operation out of the Bay of Naples, Lauria sailed for Messina, sending out smaller ships to scout the Angevin positions. In Naples, the Angevins worked to raise an army to invade Sicily.[1]

Following the consolidation of the Angevin fleets, the Angevin ships were beached stern-first near the Castellammare di Stabia. In this defensive position, the Angevin galleys were almost impervious to attack.[1] The Angevin fleet numbered some 84 galleys, 12 of which were a squadron Genoese mercenary ships commanded by Enrico de Mari. Angevin command was split between Reynald of Avella and Narjot de Tourcy, with the latter being in nominal command of the combined fleet. While the Angevins had a significant ship and manpower advantage over the Aragonese-Sicilian fleet, years of war had strained the availability of experienced crews, and many of the Angevin sailors were inexperienced.[1]

Contrasting the Angevin fleet, Lauria's Aragonese-Sicilan fleet was highly experienced, and had been commanded in battle by Lauria many times before. Although the war had drained Aragonese resources and crews, the Aragonese and Sicilians remained motivated and had a high level of confidence in their veteran commander - the Sicilian crews in particular were motivated to defend their homeland from invasion. To further motivate his men, Lauria promised that a large share of the loot of the battle would go to his captains and crews.[1]

Unable to attack the Angevin fleet as it lay beached, Lauria conducted a days-long campaign of raiding and taunting to lure the Angevins into battle; his forces harassed shipping in the gulf of Naples, raised Sicilian banners while dragging Angevin banners behind their ships, and Lauria issued a formal challenge to the Angevin leadership to meet him in battle.[1] On 23 June, the Angevin fleet slid their ships into the water and sailed to meet Lauria's fleet in the gulf.[1]

The battle began with a force of Narjot's 84 Angevin galleys advancing against a force of 40-45 Aragonese galleys under Lauria. While Lauria's forces waited in the gulf, Narjot organized his ships into diamond-like phalanxes, advancing together to try to break the Aragonese line. Each diamond was composed of nine ships, commanded by a high-ranking officer. In total, seven of these diamonds were formed, while the remaining Angevin ships followed behind as a reserve. By adopting such a formation, the Angevin ships were able to mutually support each-other while fighting in formation.[1]

As the Angevins advanced, Lauria ordered his ships to scatter in the bay - a feint, intended to force the Angevins to pursue him and expend valuable energy in a chase. This plan worked, and the Angevin formations gradually grew further apart, stripping them of their ability to come to each-others aid if attacked. Lauria's fleet then turned and charged the Angevins, taking advantage of the scattered enemy formations and devastating the Angevin vanguard, the disorganized positioning of the Angevin's ships allowing Lauria to defeat them in detail. After crushing through the Angevin vanguard, Lauria held his ships back, letting the inexperienced Angevin crews exhaust their projectiles and tire under the summer sun; soon after, the Aragonese ships closed to range with the Angevin galleys, decimating their crews with crossbows and javelins. The formations of both sides fell apart, and the battle became a fierce melee - an outcome that favored the more experienced Aragonese crews. The French-style heavy infantry were cumbersome in galley fighting, while the elite almogavar light infantry of the Aragonese proved deadly in boarding actions. Their crews depleted and oars broken, many of the Angevin galleys were captured. Seeing the destruction of the main body of the fleet, the 12 Genoese galleys fled, further disadvantaging the Angevins.[1]

The battle was a decisive victory for the Aragonese and Sicilians; 40 Angevin ships were captured and an Angevin invasion of Sicily was rendered inviable. A large number of high-ranking prisoners were taken during the battle, to the point where the battle came to be known as the "Battle of the Counts".[1]

Angevin naval power was broken after the battle and would not recover for the rest of the war. The battle effectively deprived the Angevin-French-Papal alliance of any ability to re-conquer Sicily for several years.[1]
