The Battle of Reval: A Detailed Analysis of the 1790 Conflict in the 2nd Russo-Swedish War
The Battle of Reval, fought in 1790, was a pivotal naval engagement during the Second Russo-Swedish War (1788–1790). The conflict, which occurred in the waters near the modern-day city of Tallinn, Estonia, marked a significant moment in the larger power struggle between Russia and Sweden in the late 18th century. While the Battle of Reval was part of the broader Russo-Swedish conflict, its aftermath played a crucial role in shaping the naval strategies of both empires and had far-reaching political consequences. The Russian Empire emerged victorious from this battle, a defeat that further weakened Sweden’s influence in the Baltic Sea.
Context and Background of the 2nd Russo-Swedish War
The Second Russo-Swedish War was part of a series of military conflicts between the two empires in the 18th century. Sweden, once a dominant power in the Baltic, had seen its influence waning in the aftermath of the Great Northern War (1700–1721), which had significantly reduced its territorial holdings. Russia, on the other hand, had grown in strength under the leadership of Empress Catherine the Great, with her policies focused on expanding Russian influence in the Baltic and securing Russian access to critical trade routes.

By the late 1780s, tensions between the two empires were at a high point. Sweden, led by King Gustav III, sought to reassert its power in the region, hoping to weaken Russia’s expanding influence. Catherine the Great’s Russia, on the other hand, was keen to maintain its dominance and had ambitions of further solidifying its control over territories along the Baltic coast.
This volatile situation eventually led to the outbreak of war in 1788. The conflict initially began with a series of naval engagements, and the Battle of Reval would prove to be one of the most significant battles of this naval struggle.
The Battle of Reval: Strategic Importance
The Battle of Reval took place on July 24, 1790, in the waters near the Estonian port city of Reval (now Tallinn). At the time, Reval was a key naval port for Sweden, and its control was of significant strategic importance. The battle occurred within the broader context of naval engagements between Russian and Swedish forces throughout the war, which saw both sides vying for dominance in the Baltic Sea.
The Swedish Navy, commanded by Admiral Gustav III, had established a fortified presence in the region, and their ships were anchored near Reval. On the opposing side, the Russian Navy, commanded by Admiral Gavril I. Orlov, sought to challenge Swedish supremacy and assert Russian control over the Baltic.
The Forces Involved: Sweden vs. Russia
The two naval powers that participated in the Battle of Reval, Sweden and Russia, each brought substantial fleets to the fight, but the Russian Navy had a distinct advantage in terms of both firepower and strategic positioning. While Sweden’s fleet was formidable, the Russian forces demonstrated superior coordination, naval tactics, and experienced leadership.
Sweden’s fleet, composed of several ships of the line and smaller vessels, faced off against the Russian fleet, which was similarly equipped. However, the Swedish fleet had suffered a number of strategic setbacks leading up to the battle, including difficulties with resupply and logistical coordination. On the other hand, the Russians had the advantage of better preparation, superior naval leadership, and the momentum of previous successes.
The Course of the Battle
The Battle of Reval unfolded primarily as a sea engagement, with both fleets exchanging fire in the waters around the Estonian coast. The Swedish fleet, despite its early advantage in terms of positioning, could not withstand the overwhelming force and strategic cunning of the Russian Navy. The Russians used their superior firepower and tactics to break through the Swedish defenses, forcing them to retreat.
The battle lasted for several hours, with heavy casualties on both sides. However, the decisive moment came when Swedish Admiral Gustav III’s forces were unable to respond effectively to the Russian maneuvering. In the end, the Russian fleet emerged victorious, securing a significant strategic gain for Russia in the Baltic Sea.
Aftermath and Consequences
The Battle of Reval was a significant victory for Russia and a crushing blow for Sweden. Despite the Swedish fleet’s valor and tactical attempts to outmaneuver the Russians, the battle’s outcome highlighted the growing power of the Russian Navy and the increasing difficulties Sweden faced in the war.
In the immediate aftermath, the Russian victory at Reval allowed Catherine the Great to solidify Russian control over critical parts of the Baltic. The battle also severely undermined Sweden’s ability to project power in the region and weakened its position in negotiations. Ultimately, the defeat at Reval contributed to the growing discontent within Sweden, particularly among the Swedish aristocracy, who were beginning to question the wisdom of King Gustav III’s war policies.
From a broader historical perspective, the Battle of Reval was emblematic of the shift in the balance of power in Northern Europe. With Russia’s victory, the country cemented its dominance over the Baltic region, a status it would maintain well into the 19th century. Sweden, on the other hand, found itself increasingly marginalized, its influence in the Baltic diminished as a result of this conflict.
The End of the War and the Treaty of Värälä
While the Battle of Reval was a crucial turning point, it was not the final engagement in the war. The Second Russo-Swedish War continued for another year, with sporadic fighting taking place in the region. However, the Russian victory at Reval and other subsequent Russian successes contributed to a shift in the balance of power.
In 1790, following a series of unsuccessful military campaigns, Sweden and Russia reached a peace settlement with the Treaty of Värälä. Although Sweden did not suffer any major territorial losses as a result of the treaty, the war left a lasting impact on Swedish politics and military strategy. The defeat at Reval was one of the contributing factors to King Gustav III’s declining popularity and his eventual assassination in 1792.
For Russia, the war served as a demonstration of its growing power in the Baltic and a reaffirmation of its naval strength. The Treaty of Värälä further cemented Russia’s position in the region, making it the dominant naval power in the Baltic Sea.
Conclusion: The Battle’s Legacy
The Battle of Reval stands as a significant moment in the history of naval warfare, the Second Russo-Swedish War, and the broader political landscape of 18th-century Europe. While it may not be as well-known as some other historical battles, its impact on the balance of power in the Baltic cannot be overstated. Russia’s victory demonstrated the importance of naval dominance and signaled the rise of Russian power in Northern Europe.
For Sweden, the battle represented a turning point, signaling the decline of its once-proud naval empire. The defeat at Reval, combined with other factors, marked the beginning of a long period of political and military challenges for Sweden.
Ultimately, the Battle of Reval exemplified the shifting tides of European power during the late 18th century and served as a reminder of the crucial role that naval warfare played in determining the fate of empires. The legacy of this battle remains a testament to the changing dynamics of the region and the enduring influence of naval power in shaping the course of history.
