Upon the extinction of the house of Valois, by the assassination of Henry III. in 1589, Henry of Navarre became the rightful owner of the French throne. But his religion interfered with his claims. The League was strong in force against him: he had few friends, few fortresses, no money, and a small army. But his courage and activity made up for the scantiness of his resources. With five thousand men he withstood the Duc de Mayenne, who was pursuing him with twenty-five thousand, and gained the battle of Arques, in spite of the disparity. This extraordinary result may probably be ascribed in great measure to the contrast of personal character in the two generals. Mayenne was slow and indolent. Of Henry it was said, that he lost less time in bed than Mayenne lost at table; and that he wore out very little broad-cloth, but a great deal of boot-leather. A person was once extolling the skill and courage of Mayenne in Henry's presence. "You are right," said Henry, "he is a great captain, but I have always five hours' start of him." Henry got up at four in the morning, and Mayenne about ten.
The battle of Arques was fought in the year of his accession. In the following year, 1590, he gained a splendid victory at Ivri, over the Leaguers commanded by Mayenne, and a Spanish army superior in numbers. On this occasion he made that celebrated speech to his soldiers before the battle: "If you lose sight of your standards, rally round my white plume; you will always find it in the path of honor and glory." Nor is his exclamation to his victorious troops less worthy of record: "Spare the French!"
Paris was soon blockaded, but the Parliament swore on the Gospels, in the presence of the Legate and the Spanish Ambassador, to refuse all proposals of accommodation. The siege was pushed to such extremities, and the famine became so cruel, that bread was made of human bones ground to powder. That Henry did not then master the capital, where two hundred thousand men were maddened with want, was owing to his own lenity. He declared that he had rather lose Paris, than gain possession of it by the death of so many persons. He gave a free passage through his lines to all who were not soldiers, and allowed his own troops to send in refreshments to their friends. By this paternal kindness he lost the fruit of his labors to himself; but he also prolonged the civil war, and the calamities of the kingdom at large.
