First siege Verdugo's forces marched to Coevorden via the Bruges Essche road in October 1593. The Spaniards thereon laid a
dike via
Klooster to
De Haar establishing a tight blockade. Verdugo however was not familiar with the climate of Coevorden, and as well as a lack of fuel and food, disease took hold of the Spanish camp - many soldiers of which succumbed to. In addition, a great many deserted; one company shrank from 500 to 100 men. Soldiers who were looking for fuel and food then brought disease to the surrounding villages where whole families were infected and died. The garrison however was well supplied and the defences were strong - the blockade took no effect but cost Verdugo's force dearly. Verdugo realised by November that he had neither the munitions nor provisions for a long siege. Winter was coming and Verdugo had no choice but to retire from the fortress, the States forces were aware of this, but thought it was unnecessary to interfere with the Spanish retirement. They too went into winter quarters.
Second siege Although the Spanish went into winter quarters, a tight blockade was put on Coevorden. Despite this, supplies still managed to get through, as well as reinforcements. In March 1594 Verdugo appeared before Coevorden with 8,000 troops, including 2,000 cavalry. Having surrounded the city, they demanded the surrender, but this was rejected by Van Eussum. He hoped for relief soon, but at the same time the Spanish dug siege positions and installed bastions around the key positions.
Relief On hearing of the news of Verdugo's siege, Maurice with his force (which included twelve companies of English and ten Scots totalling 5,000 troops under Francis Vere) quickly moved from
Zwolle and marched his force to Coevorden. Count William Louis, with his thirteen companies of Frisians, had fortified the area known as the Bourtange Marsh so that Maurice could move in quickly and take Verdugo at a disadvantage. William Louis soon joined Maurice and Vere on the road between
Vecht and the Bourtange marsh totalling 9,600 soldiers and 1,900 cavalry. Count
Philip of Hohenlohe-Neuenstein was sent with twenty Dutch companies to cover the southern borders against Verdugo's army of reinforcements under
Frederik and
Herman van den Bergh of which neared 8,000 men. Meanwhile, Maurice's forces soon approached Coevorden and started to dig trenches in front of the Spanish force surrounding the city. Verdugo reconnoitred the position but found the Anglo-Dutch to be impregnable and established on his line of communications. He then called a council of war and decided that to remain would result in destruction and that to attack was suicidal. On the night of May 7, the Spanish broke camp, burning everything they didn't need and retreated from the siege works. The siege of Coevorden had ended after thirty one weeks. ==Aftermath==
