The borders of the present-day Netherlands were largely defined by the campaigns of Maurice of Orange. The Dutch successes owed not only to his tactical skill but also to the financial burden Spain incurred replacing ships lost in the disastrous campaign of the Spanish Armada in 1588, and the need to refit its navy to recover control of the sea after the subsequent English counterattack. One of the most notable features of this war are the number of mutinies by the troops in the Spanish army because of arrears of pay. At least 40 mutinies in the period 1570 to 1607 are known. In 1595, when Henry IV of France declared war against Spain, the Spanish government declared bankruptcy again. However, by regaining control of the sea, Spain was able to greatly increase its supply of gold and silver from the Americas, which allowed it to increase military pressure on England and France.
