How to find a civil war army
Feeding an early-modern army was a major logistical problem. The New Model Army had a centralised supply system to take care of most things (weapons, armour, clothing, horses, saddles) but food was a big exception. Aryeh Nusbacher has noted that the quantities of food supplied through centralised purchasing were far too small to keep the army fed (see “Civil Supply in the Civil War”, English Historical Review (115, 2000, pp. 145-60), which summarises some of the most important points in his PhD thesis). His answer to this problem is that food was mostly supplied by private victuallers who brought food from London and sold it directly to the soldiers. This makes a lot of sense, because compared to the population of London (estimates for the civil war period are usually between 200,000 and 300,000), feeding an army of 20,000 was not such a big deal. In contrast, most of the areas where the army campaigned were unlikely to have enough food supplies to support the army. Ben Coates (The impact of the English Civil War on the economy of London, 1642-50, 2004, ISBN: 0754601048, pp. 91-2) questioned this view, partly because Ian Archer pointed out that it would have been difficult for the victuallers to find the army when it was on the move. Having spent years studying military operations and logistics I would suggest the opposite: it would have been difficult to miss an English Civil War field army.
