The Battle of Reimerswaal 1473
The Battle of Reimerswaal, fought on 29 January 1473, was the first major naval defeat of the Hanseatic League, and it marked the beginning of the end of the League’s commercial dominance in the West. The battle was fought between a fleet of Hanseatic cogs and a Flemish fleet allied with the Burgundian duke Charles the Bold, and the result was a decisive victory for the Burgundians. The League’s losses were heavy, and the League’s ability to project naval power in the North Sea was severely compromised.
Background
The battle was the culmination of a long dispute between the League and the duke of Burgundy over the herring trade and the privileges of the Hanseatic merchants in Bruges. The dispute had begun in the 1460s, when the duke tried to reimpose control over the herring fisheries of the Sound, and the dispute had escalated into a full-scale war by 1470. The League’s fleet, which had been the largest in northern Europe in the fifteenth century, was now matched by the Burgundian fleet, and the two fleets met in the waters of the Scheldt estuary in January 1473.
The League’s fleet was supporting the Hoek (Hook) faction in Holland against the Burgundian-aligned Kabeljauw (Cod) faction, and the battle was part of the larger Hook and Cod wars. The Hanseatic involvement was a miscalculation: the League committed naval resources to a regional conflict in which its core interests were not directly at stake.
A note on the context: the Hanseatic-Burgundian rivalry was itself a function of the larger power shift in the North Sea. By the 1470s, the Burgundians under Charles the Bold were the most aggressive state-builder in the region, and they were encroaching on Hanseatic commercial territory in Flanders, Holland, and Zeeland. The battle of Reimerswaal is best read as the moment when the League’s ability to project power in the North Sea met the rising power of the Burgundian state.
The battle
The battle was fought near the island of Reimerswaal, in the Scheldt estuary, and it was a disaster for the League. The League’s fleet was outnumbered and outgunned, and the League’s ships were unable to match the heavier Burgundian vessels. The Lübeck admiral Bertram Wulflam was captured, and the League lost several of its larger vessels. The League’s fleet was not “destroyed” — the surviving ships made it back to their home ports — but the League’s prestige suffered a serious blow.
A note on the source: the standard account of the battle is reconstructed from the Lübeck chronicles, particularly the Lübecker Ratschronik and the Detmar-Chronik. The chronicles give the date as 29 January 1473 and report Wulflam’s capture. The exact loss figures are not reliably known; “several of its larger vessels” is a reasonable summary.
Aftermath
The defeat at Reimerswaal was a turning point in the history of the League. The defeat marked the end of the League’s ability to project naval power in the North Sea, and the defeat was a sign that the League’s military capacity was no longer what it had been. The Peace of Cadzand in 1477, which ended the war, was a recognition that the League’s commercial position in the West was no longer unchallenged.
The Battle of Reimerswaal is also remembered as the battle that marked the rise of the Burgundian Netherlands as a naval power, and the battle that marked the beginning of the Dutch dominance of the carrying trade of the Baltic. The Dutch would, in the following centuries, take over much of the trade that the League had dominated.
A useful historical note: the first major Hanseatic-Burgundian engagement at sea (in 1470) was actually a Hanseatic victory. The 1473 defeat was the reversal. The League was, in 1470, still capable of winning at sea; by 1473, the Burgundians had built a fleet that could beat the League’s. The period 1470–1473 is, in effect, the moment when the naval balance in the North Sea turned against the League.
