Being obliged to leave his country on account of the troubles by which it was agitated, he commenced a soldier of fortune, and served successively in the armies of Holland, England, France, Portugal, and Brandenburgh.

He attained to the dignities of mareschal in France, grandee in Portugal, generalissimo in Prussia, and duke in England.
He professed the protestant religion; was courteous and humble in his deportment; cool, penetrating, resolute, and sagacious; nor was his probity inferior to his courage.

This battle likewise proved fatal to the brave Caillemote, who had followed the duke's fortunes, and commanded one of the protestant regiments.

After having received a mortal wound, he was carried back through the river by four soldiers, and though almost in the agonies of death, he with a cheerful countenance encouraged those who were crossing to do their duty, exclaiming, "_A la gloire, mes enfans; a la gloire_.

To glory, my lads; to glory!" The third remarkable person who lost his life on this occasion was Walker the clergyman, who had so valiantly defended Londonderry against the whole army of king James.
