The Siege of Schenkenschans (30 July 1635 – 30 April 1636) was one of the more important sieges of the Eighty Years' War. The capture of the strategically located fortress by the Spanish army of the Cardinal-Infante Ferdinand of Austria opened up the Dutch Republic to a possible invasion. The Dutch Stadtholder, Fredrick Henry had to pull out all stops to counter this strategic threat and recapture the fortress in an epic siege that lasted even through the winter months. He succeeded in doing so after nine months.


The Schenkenschans by Claes Janszoon Visscher.

The fortress with the name Schenkenschans (English: Schenk's Sconce, Spanish language: Esquenque ) was founded by the German mercenary commander Maarten Schenk van Nydeggen on the orders of stadtholder Adolf van Nieuwenaar in 1586. Its location was strategically chosen, because it dominated the place where in 1586 the Rhine and the Waal River forked (currently these rivers split further west; the fork was moved to improve river traffic and prevent flooding[1]). An army that approaches from the East here has a choice of marching along the right bank of the Rhine, through the "back door" of the Dutch Republic, thrusting straight to the Dutch heartland; or take a more southerly route through the Betuwe; or take the third route West, entering the area between the Waal and the Meuse River. In all three cases the rivers form an ideal supply line. However, that supply line was cut off by the Schenkenschans.

The Dutch dominated the area (that also includes nearby Cleves) during most of the war with Spain. The fortress was much improved after its humble beginnings and in its new form was a fine example of Star fort architecture.

Capture by the Spanish Army

In 1635 the Dutch Republic concluded an alliance with France with the objective of taking on the Spanish Army of Flanders from two sides, in the hope of breaking the strategic stalemate in the Eighty Years' War and dividing up the Spanish Netherlands between the two partners in the alliance. The Dutch and French invaded from two sides in June, 1635, and joined forces in the valley of the Meuse in July, while the Spanish field army under the Cardinal-Infante fell back to cover Brussels. The invading armies (60,000 strong) captured a few smaller places before investing Leuven. But this siege ended in a fiasco because of bad logistics and organization, and because the French army was decimated by the plague. This failure allowed the Spanish forces to take the initiative and soon the invaders were forced into a headlong retreat.[2]

The Cardinal-Infante pushed the Franco–Dutch army back to the Dutch border. He made a north-easterly thrust to the Rhine in the direction of Cleves. A party of 500 German mercenaries under Lt.-Col. Eyndhouts, roaming on his left flank, managed to surprise the fortress of Schenkenschans that at the time had a garrison of only 120, in the night of 27/28 July. The garrison were massacred.[3] Spain then put a large garrison in the fortress, at first under the command of Eyndhouts (who died in action on November 30).[4]

The siege

The Dutch brought up reinforcements right away, but could not prevent the occupation by a Spanish army of 20,000 of the Duchy of Cleves during August and September. This army threatened an invasion of the Dutch heartland and it was therefore essential that this threat be countered. Frederick Henry personally started the siege of Schenkenschans within days of its fall, but soon transferred command to his cousin John Maurice, Prince of Nassau-Siegen. The besieging army had a strength at its peak of 30,000 men, while the size of the garrison was 1,500 men.[5]

The terrain made the siege especially difficult. The fortress was built on an island between the two rivers that functioned as a moat. An escalade would therefore be difficult, as the garrison was unlikely to let itself be surprised. Mining would have been impossible because of the water-logged terrain, and for the same reason the fortress could not be closely invested with entrenchments. On the other hand, the Dutch could and did use the terrain to protect the besieging army from Spanish efforts at relief by inundations. In any case, there seemed to be no option but to starve out the well-provisioned garrison and meanwhile to attempt to pound the fortress to rubble with siege artillery. This the Dutch did with alacrity. The fortress was bombarded from all sides, even by river gun-boats on the Waal.[6]

The effects of such bombardments were terrible. According to eye-witnesses:

One could hear the screaming and crying in the sconce while the air was filled with smoke and flying debris for two hours on end.[7]

After one such bombardment. Nevertheless, the garrison held out for nine months despite the terrible circumstances and the high casualties. When finally John Maurice negotiated an honorable surrender with the new governor of the fortress, Gomar de Fourdin, only 600 survivors walked out on April 30, 1636.[6]


The population of the Dutch Republic was elated by the surrender, whereas the Spanish chief minister Olivares fell victim to despondency. He wrote to the Cardinal-Infante:

...pues veo, Señor, que se ha perdido la mayor joya que el rey nuestro Señor tenia en esos estados para poder acomodar sus cosas con gloria ... grande golpe, Señor, para el rey nuestro Señor, grande para toda España .[8]

Though there may not have been a direct link with the loss of Schenkenschans for Spain,[9] the Cardinal-Infante decided to change the focus of the Spanish offensive to France in the Summer of 1636. To everybody's surprise this led to a collapse of the French defenses and to a deep incursion into France, as far as Corbie.[10]

The fortress of Schenkenschans once more played an important role in Dutch history when it fell without a shot being fired to the French invading armies during the Rampjaar on 21 June 1672. The governor of the fortress at the time was the 22-year-old son of a Nijmegen regent by the name of Ten Hoven or Ten Haef, who evidently was in over his head and surrendered the fortress in exchange for a chance to march the garrison off to Friesland[11] By that time the rivers near the fortress had become so shallow that the French army could easily ford them. The fall of the fortress made the subsequent French invasion of the Republic much easier.
