These are strong opinions and expressions, and as their general acceptance would logically render war impossible, it is no small gain to have in their favour so great an authority as Grotius. But it is an even greater gain to be able to quote on the same side an actual soldier. Sir James Turner at the end of his military treatise called ‘Pallas Armata,’ published in 1683, came to conclusions which, though adverse to Grotius, contain some remarkable admissions and show the difference that two centuries have made on military maxims with regard to this subject. ‘It is no sin for a mere soldier,’ he says, ‘to serve for wages, unless his conscience tells him he fights in an unjust cause.’ Again, ‘That soldier who serves or fights for any prince or State for wages in a cause he knows to be unjust, sins damnably.’ He even argues that soldiers whose original service began for a just cause, and who are constrained by their military oaths to continue in service for a new and unjust cause of war, ought to ‘desert their employment and suffer anything that could be done to them before they draw their swords against their own conscience and judgments in an unjust quarrel.’[318] These moral sentiments of a military man of the seventeenth century are absolutely alien to the military doctrines of the present day; and his remarks on wages recall yet another important landmark of ancient thought that has been removed by the progress of time. Early Greek opinion justly made no distinction between the mercenary who served a foreign country and the mercenary who served his own. All hired military service was regarded as disgraceful, nor would anyone of good birth have dreamt of serving his own country save at his own expense. The Carians rendered their names infamous as the first of the Greek race who served for pay; whilst at Athens Pericles introduced the custom of supporting the poorer defenders of their country out of the exchequer.[319] Afterwards, of course, no people ever committed itself more eagerly to the pursuit of mercenary warfare.
