Battle of Nieuwpoort The Battle of Nieuwpoort , between a Dutch army under Maurice of Nassau and Francis Vere and a Spanish army under Albert of Austria , took place on 2 July 1600 near the present - day Belgian city Nieuwpoort . Campaign . Against Maurice ' s complaints , the States General under Johan van Oldenbarneveldt had ordered Maurice to take the army , march south along the coast and take the pirate nest of Dunkirk . The divergence of opinion on this matter between Maurice and Van Oldenbarneveldt were the first signs that the two " de facto " leaders of the Dutch Republic were beginning to drift apart . This rivalry would eventually lead to the arrest and execution of Van Oldenbarneveldt in 1619 . It was thought that the vicious and long - continued mutiny of a great part of the Spanish troops would make it impossible for the Archduke to collect an army for the relief of Nieuwpoort . By 21 June Maurice had collected an army for the operation of 12 infantry regiments and 25 cavalry cornets : some 12 , 000 Foot and 2 , 000 Horse . On the 22nd , he crossed the Scheldt Estuary in a multitude of small vessels and moved to Ostend ; his base of operations . He left there half a regiment and four cornets to reinforce the garrison and on the 30th started for Nieuwpoort . When Maurice arrived in front of the place on 1 July , he sent 2 / 3 of his force across the Yser River to blockade it from the West . That night , while he was making preparations for a regular siege , he received news that the Archduke was close at hand with a field army . He knew he was cut off from his base ; so he ordered his cousin Ernst Casimir ( Ernst Casimir I of Nassau - Dietz ) with a force to delay the advancing Spanish while he was bringing the best part of the army to cross again the Yser and rejoin the rest of the army to face the Archduke . He had no option left but to present battle or risk a potentially disastrous retreat by sea . Ernst Casimir was ordered to seize the Leffinghen bridge , he commanded the Edmonds regiment ( Scottish ) and the Van der Noot regiment ( Dutch ) together with four cornets of cavalry and 2 guns , but when he arrived he found that the enemy was already in possession of it . Ernst deployed his force behind a ditch , hoping to fight a delaying action , but the Spaniards were already in great strength across the bridge and charged right home , piercing his centre . The infantry was routed at once and the cavalry fled in panic : the Scots were killed almost to a man and the Dutch fared only slightly better , taking refuge in Ostend . For all purposes , Ernst ' s command had ceased to exist . After that cheap victory , the Archduke held a conference with his captains . Most urged to entrench the army across the road to Ostend , forcing Maurice to attack along a narrow front where the Dutch cavalry , mostly heavy , would not be effective against the lighter Spanish cavalry . However , the mutineers , who had been rallied by the Archduke on the promise of free plunder , were eager for a fight and out - argued the rest . The army therefore advanced in battle order along the coast . It was mid - day and the tide was coming in ; so that in the end they were forced to abandon the shrinking beach and climb slowly up the slippery sanddunes . Maurice just had time to assemble his whole army to face the Archduke . Battle . The Dutch first line of infantry was placed in a strong defensive position , on top of a stretch of dunes , with guns covering both flanks with enfilade fire . Maurice had posted his best regiments there , under the command of the experienced Francis Vere , who ruled out sending any advance party , awaiting for the Spanish army to arrive . The Spanish sent a screen of 500 harquebusiers to cover their advance ; but soon the two unruly mutineer regiments in the vanguard started the attack with a rash charge up the hill . They were repulsed in disorder , while the light cavalry , counter - charged by the Dutch cuirassiers , were routed . It was then time for the second line of the Spanish infantry to advance . The Sapena and Ávila Tercios in the Dutch right made quick progress against the Frisian regiment , and Maurice sent his entire second line to protect that sector , stabilizing the front . Maurice then sent his entire cavalry against the Spanish flank , except for the small body of cavalry in the second line that he kept in reserve behind the infantry . The Dutch cuirassiers easily routed the lighter Spanish cavalry , and the mutineer cornets , that had just rallied , fled the battlefield never to return . However , the Dutch were checked by the Spanish third line of infantry , supported by some guns , and retreated with heavy losses . Meanwhile on the Dutch left , the English regiments faced the veteran tercio s of Monroy and Villar ; the elite of the Spanish infantry . The English , well drilled in Maurice ' s new tactics , kept a rolling fire on the Spaniards and advanced up the slope at a steady pace , covered by a screen of skirmisher harquebusiers . The fight was even for a time , until it came to the push of pike , the Spaniards finally dislodging the English from the top of the hill . Francis Vere , seeing the risk , asked for reinforcements , but they did not arrive in time and the English were finally routed . However , the Spaniards , exhausted after a day of fighting and marching on difficult terrain , pressed their advantage very slowly . Even more dangerously , they were disordered , with musket and pike units mixed . Maurice sent his reserve cavalry against them , only 3 cornets strong . Their well - timed charge was unexpectedly very successful . The Spaniards were thrown into confusion and started a slow retreat . Vere , who had been able to rally some English companies behind a battery , joined the fight , and he was reinforced by the regiments in the third line that had finally arrived . The Spaniards , heavily assailed , retreated in disorder . On the Dutch right , the Archduke had committed his third line into the assault . Maurice saw his chance and asked his tired cavalry for one last effort . Under the command of his cousin Louis , another charge was delivered and the Spanish cavalry was finally driven from the field . The Spanish infantry , already engaged at the front , was this time unable to repulse the attack on their flank and started to give ground . After a while , the front crumbled and , one after another , all units were running in confusion , leaving behind their guns . The survivors scattered in all directions , but the inactivity of the Dutch garrison in Ostend allowed the Spanish army to avoid total destruction . Spanish losses were high ; about 2 , 500 casualties , including many officers . The artillery train was also lost . Most of the casualties were suffered by the elite units of the second line , veteran soldiers who were very hard to replace . Dutch losses were also high . With the casualties at Leffinghen included , they amounted to around 2 , 000 . Again , it was the best regiments , Scottish and English veterans , who suffered most . Conclusion . Although Maurice had driven a Spanish army from the field , a rare feat in the 16th century , the battle achieved nothing . The Dutch lines of communication had already been stretched to the limit and Maurice was soon forced to withdraw as well . The Flemish , which Maurice had hoped to rally to his revolt , remained loyal to the Spanish monarchy . Moreover , the great port of Dunkirk , which had been the principal objective of Maurice ' s campaign , lay out of reach and in Spanish hands . " The Dunkirkers " , would continue to prey on Dutch and English trade . On the tactical side , the battle was paradoxical . Maurice ' s army had beaten a Spanish army . However , his reformed infantry had been dislodged from a strong defensive position by the Spanish infantry using its traditional methods and it was only his cavalry that had saved the Dutch from defeat . Strategically , the lesson was that it was more advantageous to besiege and capture towns than to win battles . This fact would continue to characterize operations in the Eighty Years ' War .
