The presence of a French squadron in the Straits of Gibraltar at this particular moment may be explained in a few sentences. Napoleon had woven afresh the web of those naval "combinations" so often torn to fragments by British seamanship and daring. He had persuaded or bullied Spain into placing under the French flag a squadron of six line-of-battle ships, including two leviathans of 112 guns each, lying in the harbour of Cadiz. With haughty, it might almost be said with insolent daring, a couple of British seventy-fours--sometimes, indeed, only one--patrolled the entrance to Cadiz, and blockaded a squadron of ten times their own force. Napoleon's plan was to draw a strong French squadron, under Admiral Linois, from Toulon, a second Spanish squadron from Ferrol, unite these with the ships lying in Cadiz, and thus form a powerful fleet of at least fifteen ships of the line, with a garnishing of frigates. Once having got his fleet, Napoleon's imagination--which had a strong predatory bias--hesitated betwixt two uses to which it could be turned. One was to make a dash on Lisbon, and require, under threat of an instant bombardment, the delivery of all British ships and goods lying there. This ingenious plan, it was reckoned, would fill French pockets with cash and adorn French brows with glory at one stroke. The amount of British booty at Lisbon was computed--somewhat airily--at 200,000,000 pounds; its disappearance would send half the mercantile houses of Great Britain into the insolvency court, and, to quote a French state paper on the subject, "our fleet, without being buffeted about the sea, would return to Brest loaded with riches and covered with glory, and France would once more astonish Europe." The alternative scheme was to transport some 32,000 new troops to Egypt and restore French fortunes in that country. Meanwhile Great Britain took energetic measures to wreck this new combination. Sir James Saumarez, in the _Caesar_, of eighty guns, with six seventy-fours, was despatched to keep guard over Cadiz; and he had scarcely reached his station there when a boat, pulling furiously over from Gibraltar, reported that Admiral Linois' squadron had made its appearance off the Rock, beating up westward. The sails of the _Caesar_ were instantly swung round, a many-coloured flutter of bunting summoned the rest of the squadron to follow, and Saumarez began his eager chase of the French, bearing away for the Gut under a light north-west wind. But the breeze died down, and the current swept the straggling ships westward. All day they drifted helplessly, and the night only brought a breath of air sufficient to fan them through the Straits.
