Any Troops Could Fight a Battle But It Requires Trained Veterans to Win a Skirmish
Although military historians have tended to confine their attention to the formal engagements of the war [in the Low Countries], to the sieges, battles and major manoeuvres, these events formed only the tip of the iceberg of military conflict. Beneath the interplay of the big battalions, at least until 1590 [C.E.], smaller parties of troops fought, intrigued and killed ceaselessly for the control of villages. Spain’s piecemeal reconquest of the areas in rebellion in the first phase of the war created a jagged “floating” frontier, running from one fortified town to another, from one village to the next. Until 1594 the frontier ran from Groningen in the north down to Liège and then westwards to the Flemish sea-coast. All along this invisible line hostile parties of troops conducted a gruelling war of skirmish and surprise. In this situation…war became a matter of “fights, encounters, skirmishes, ambushes, an occasional battle, minor sieges, assaults, escalades, captures and surprises of towns”. It resembled a series of uncoordinated guerilla conflicts rather than a single full-scale war.
These localized dog-fights, this guerre aux vaches, was a highly intensive and exhausting form of warfare. It called for troops with an unusually high degree of endurance and experience. In battles or mass manoeuvres a commander required from his men corporate discipline, good order, careful drilling in certain collective movements and above all stoicism under fire. By contrast, for the skirmish and surprise of guerilla fighting, discipline and unit-organization hardly mattered: the critical qualities were independent excellence and complete familiarity with weapons.
Sixteenth-century commanders and military commentators naturally realized that these different forms of warfare required different types of soldier: one for routine garrison duty and mass manoeuvres, the other for guerilla action. On the whole they agreed that it was more difficult to find troops who excelled in skirmish-and-surprise, in what the English called the “actions” of war. For that veterans were required. The duke of Alva always insisted that some trained troops were indispensable for success in the Low Countries’ Wars because “One cannot fight any ‘actions’ with other troops—unless it comes to a pitched battle where entire formations are engaged.” To the duke’s mind (and he had a lifetime of experience to draw on) any troops could fight a battle but it required trained veterans to win a skirmish.
