Now the defence of Brittany had been the primary ground of England's quarrel with the French; with Henry himself, however, this object had been secondary to the matrimonial alliance with Spain, from which the latter was now not likely to withdraw. Henry, moreover, had made use of the whole affair to acquire a full money-chest; and since it was of vital importance that this should be done without turning his subjects against him, it had been necessary to lend the war as popular a colour as possible. Hence it was part of his policy to emphasise at home as his ultimate end the recovery of the English rights in the French Crown, so successfully utilised by his predecessor Henry V. in the first quarter of the century. It would have been manifestly dangerous for him in establishing his dynasty to recede from a claim which both Yorkists and Lancastrians had maintained. Incidentally also, there was the matter of indemnities owing to him by Anne of Brittany for which Maximilian had been made responsible. [Sidenote 1: France makes peace] [Sidenote 2: Treaty of Etaples (Dec.)] Since then it was impracticable simply to retire, the alternative course was to demonstrate; and Henry spent the greater part of 1492 in making the greatest possible display of preparation for war on a great scale--with a view to obtaining satisfying terms of peace. The one real piece of military work taken in hand was the siege and capture of Sluys in Flanders (in conjunction with Albert of Saxony, on behalf of Maximilian); from which port much injury of a piratical order had been wrought upon English merchants. Meantime negotiations had been carried on, but with no appearance of success. At last in October the King actually crossed the Channel to take command of the army of invasion; and sat down before Boulogne. Then on a sudden the air cleared. Charles in fact did not want a serious English war, out of which he could make nothing. But he had developed a very keen ambition to enter Italy and win the Crown of Naples. Henry by himself, or even in conjunction with the much offended Maximilian, was hardly likely to penetrate very far into France, if the forces of that kingdom were arrayed against him; but while he threatened, Charles could not move on Italy; moreover, his presence was an encouragement to those of the nobility whose allegiance was doubtful. So the French King resolved to buy off the English King at his own price. Lewis XI., threatened by Edward IV., had agreed to pay what Edward called a tribute, in return for which he held his claim to the French throne in abeyance. Henry need have no qualms about following his Yorkist predecessor's example. Beyond that, Charles was prepared to pay off the Brittany indemnities. Thus Henry secured Peace with Honour and a solid cash equivalent for his expenditure; besides being able to silence the complaints of the warlike by emphasising the gravity of embarking on a great campaign with winter coming on. He threw over
