In the meantime the war between Charles and Francis had broken out. French and Flemish cruisers captured prizes, or fought battles, in the mouths of English rivers or under the windows of English towns, and both belligerents too frequently made what they deemed lawful prey of the ships of England. Even when the courts of Brussels and Paris were making professions of good-will, the cruisers of both governments openly seized English traders, and Henry had for a time to submit, and to leave those of his subjects who resided on the coasts to such inadequate defences as they could themselves provide. So daring were the acts of these piratical cruisers that two French ships attempted even to cut out two merchantmen from the harbour of Dartmouth, and only failed in this exploit through the bravery of the mayor and inhabitants of that town, who attacked them with their boats; nay, more, the rival fleets of France and Spain did not scruple to test their strength in deadly combat in the harbour of Falmouth,[97] and not unfrequently placed, at other times, embargoes on vessels entering the Thames. [Sidenote: Royal fleet equipped and despatched from Portsmouth.] [Sidenote: Its first engagement.] [Sidenote: Increase of the French fleets.] The London merchants declared that, although the country was nominally at peace, their ships could not venture out of port; but every remonstrance, though made in no measured terms at the courts of Paris and Brussels, and received with courtesy and verbal apologies, was practically ineffectual in suppressing these wanton depredations. Unfortunately, at this juncture, Henry could not afford to declare war, as his exchequer was very poorly furnished; but the country itself had not sunk so low as to be unable to defend its own coasts and its own traders. Sufficient money having, through the aid of the London merchants, been at last found for their immediate purposes, a small but admirably equipped fleet was silently fitted out at Portsmouth, secrecy being observed as far as possible, in the hope of taking the offenders by surprise. Sweeping out into the Channel, this fleet soon fell across four French ships of war which had been plundering English merchant vessels in the vicinity of Mount’s Bay, and closing against heavy odds, sunk one of them and drove the other three from the coast.[98] The time had, indeed, arrived when it became essential to the independence of England that a fleet sufficient to command the Channel should be permanently maintained. France, having resolved on open war, was straining every nerve to humiliate her old and inveterate rival. One hundred and fifty of her ships of war and twenty-five swift galleys had assembled at the mouth of the Seine ready to convoy transports with sixty thousand troops on board; the intention being to occupy the Isle of Wight as a prelude to a further attack on Portsmouth, and the destruction of the small English fleet collecting at Spithead.
