The eyes which looked bravely at him were full of tears; but the girl shook the drops from her long lashes as she threw back her head, and spoke with unfaltering lips.

"I would hold no man back from his duty; least of all the man I love."

In a moment his arm was about her. The troth plight, spoken amid the clang of arms and the rattle of musketry, was but three days old; and the strange sweetness of it had penetrated the life of the English Captain in a fashion which he had no skill to analyse. But in these stern days there was little scope for the sweetness of spoken love; and even the minutes snatched from the pressing needs of garrison life were few and far between.

But Hart had volunteered the second time for a service of extra peril, and he had come to speak a farewell to his love—a farewell which both knew might be final.

How is it possible the thing should be done? It has come to this, that if help comes not, Sluys must fall. Alexander Farnese and his Spanish host will score another triumph for tyranny and the Inquisition!"

A shudder ran through the girlish frame at the sound of that word, more hateful and terrible to the party of freedom than any other which could be spoken. Then her eyes flashed with a spark as of fire, and, flinging back her head, she cried:
