The Siege of La Rochelle was one of the great political events of the reign of Louis XIII, and one of the great military enterprises of the cardinal. It is, then, interesting and even necessary that we should say a few words about it, particularly as many details of this siege are connected in too important a manner with the story we have undertaken to relate to allow us to pass it over in silence.

The political plans of the cardinal when he undertook this siege were extensive. Let us unfold them first, and then pass on to the private plans which perhaps had not less influence upon his Eminence than the others.

Of the important cities given up by Henry IV to the Huguenots as places of safety, there only remained La Rochelle. It became necessary, therefore, to destroy this last bulwark of Calvinism--a dangerous leaven with which the ferments of civil revolt and foreign war were constantly mingling.

Spaniards, Englishmen, and Italian malcontents, adventurers of all nations, and soldiers of fortune of every sect, flocked at the first summons under the standard of the Protestants, and organized themselves like a vast association, whose branches diverged freely over all parts of Europe.

La Rochelle, which had derived a new importance from the ruin of the other Calvinist cities, was, then, the focus of dissensions and ambition. Moreover, its port was the last in the kingdom of France open to the English, and by closing it against England, our eternal enemy, the cardinal completed the work of Joan of Arc and the Duc de Guise.

Thus Bassompierre, who was at once Protestant and Catholic--Protestant by conviction and Catholic as commander of the order of the Holy Ghost; Bassompierre, who was a German by birth and a Frenchman at heart--in short, Bassompierre, who had a distinguished command at the siege of La Rochelle, said, in charging at the head of several other Protestant nobles like himself, "You will see, gentlemen, that we shall be fools enough to take La Rochelle."

And Bassompierre was right. The cannonade of the Isle of Re presaged to him the dragonnades of the Cevennes; the taking of La Rochelle was the preface to the revocation of the Edict of Nantes.

We have hinted that by the side of these views of the leveling and simplifying minister, which belong to history, the chronicler is forced to recognize the lesser motives of the amorous man and jealous rival.
