The small ships were close inshore, the flashes from their guns growing brighter as daylight diminished and the tide turned. Owen made the signal for withdrawal and the Antigone, in company with the Harpy, Bloodhound and Archer, drew off for the night and rode out the rising gale at anchor three leagues offshore.
At daylight on the following day, 20th July, Drinkwater was awoken by Midshipman Dutfield. 'Beg pardon, sir, but Mr Fraser's compliments, sir, and would you come on deck.'
Drinkwater emerged into the thin light of early morning. The north-north-westerly wind was blowing with gale force. The Channel waves were steep, sharp and vicious and Antigone rode uncomfortably to her anchor. The flood tide was just away and the frigate lay across wind and tide, rolling awkwardly. But it was not this circumstance that the new lieutenant wished to draw to Drinkwater's attention.
'There, sir,' he pointed, 'just beyond the low-water mark, lines of fascines to form a rough wall with artillery… see!' Fraser broke off his description as the French gave evidence of their purpose. The flash of cannon from the low-water mark was aimed at the gun-brigs anchored inshore. Out of range of the batteries along the cliffs, they were extremely vulnerable to shot from a half-mile nearer. The French, as if demonstrating their ingenious energy, had made temporary batteries on the dry sands and could withdraw their guns as the tide made. What was more, shot fired on a flat trajectory so near the surface of the sea could skip like stones upon a pond. They'd smash a gun-brig with ease and might, with luck, range out much further.
'It's bluidy clever, sir.'
'Aye, Mr Fraser… but why today?' Drinkwater adjusted his glass and immediately had his answer. At the hour at which it was normal to see lines of infantry answering the morning roll-call he was aware of something very different about the appearance of the French camps. Dark snakes wound their way down towards the dip in the hills where the roofs and belfries of Boulogne indicated the port.
'By heaven, Mr Eraser, they're embarking!'
'In this weather, sir?'
'Wind or not, they're damned well on the move…' The two officers watched for some minutes in astonishment. 'There are a lot less bateaux in the anchorage this morning,' Drinkwater observed.
'Happen they've hauled them inshore to embark troops.'
'That must have been a ticklish business in this wind with a sea running.'
'Aye.'
As the tide made, Owen ordered his tiny squadron under weigh and once again Antigone closed the coast. By now the batteries along the tideline had been withdrawn and there was sufficient water over the shoals for the bigger frigates to move in after the sloops and gun-brigs.
At noon Antigone came within range of the batteries and Drinkwater opened fire. After the weeks of aimless cruising, the stench of powder and the trembling of the decks beneath the recoiling carriages was music in the ears of Antigone's crew.
Their insolence was met by a storm of fire from the shore; it seemed that everywhere the ground was level the French had cannon. The practical necessity of having to tack offshore in the northerly wind allowed them to draw breath and inspect the ship for damage. There was little enough. A few holes in the sails and a bruised topgallant mast. Astern of them the gun-brigs and sloops were snapping around the two or three luggers that were trying to work offshore. The flood tide swept them northwards and, off Ambleteuse, Drinkwater gave orders to wear ship.
'Brace in the spanker there! Brace in the after-yards! Up helm!' The after-canvas lost its power to drive the frigate as Drinkwater turned her south.
'Square the headyards! Steady… steady as she goes!'
'Steady as she goes, sir.'
'Square the after-yards!'
Antigone steadied on her new course, standing south under her three topsails, running before the wind inside the shoals and parallel with the coast. It wanted an hour before high water but here the tide ran north for several hours yet and they could balance wind and tide, checking the ship's southward progress against the tide, and thus wreak as much havoc as they possibly could while the smoke from their own guns hung over their deck masking them from the enemy. The motion of the deck eased considerably.
'Mr Rogers! Shift over the starbowlines to assist at the larboard batteries. Every gun-captain to choose his target and fire as at a mark, make due allowance for elevation and roll. You may open fire!'
Drinkwater stared out to larboard. They were a mile from the cliffs at Raventhun and suddenly spouts of water rose on their beam. Drinkwater levelled his glass.
'Mr Gillespy!'
'Sir?'
'D'you see that square shape over there, where the ground falls away?'
The boy nodded. 'Yes, sir.'
'That's Ambleteuse fort. Be so kind as to point it out to Mr Rogers so that he may direct the guns.'
The little estuary that formed the harbour opened up on their beam as Antigone exchanged shot with the fort. Within the harbour they could see quite clearly a mass of rafted barges crammed with soldiers, rocking dangerously as the sharp waves drove in amongst them.
A shower of splinters sprouted abruptly from the rail where a ball struck home and more holes appeared in the topsails. Amidships the launch was hit by three shot within as many minutes and then they were passing out of range of the fort's embrasures. Rogers was leaping up and down from gun to gun, exhorting his men and swearing viciously at them when their aim failed. As the land rose again a battery of horse artillery could be seen dashing at the gallop along the cliff. Suddenly Drinkwater saw the officer leading the troop fling up his hand and the gunners rein in their horses.
'Mr Rogers! See there!' Rogers narrowed his eyes and stared through the smoke that cleared slowly in the following wind. Then comprehension struck him and he leant over the nearest gun and aimed it personally. The Frenchmen had got their cannon unlimbered and were slewing them round. They were shining brass cannon, field pieces of 8- or 9-pound calibre, Drinkwater estimated, and they were ready loaded. He saw white smoke flash from an almost simultaneous volley from the five guns and a second later the shot whistled overhead, carrying off the starboard quarter-boat davits and dumping the boat in the sea alongside, where it trailed in its falls amongst the broken baulks of timber.
Amidships Rogers was howling with rage as his broadside struck flints and chunks of chalk from the cliff a few feet below the edge. But his next shots landed among the artillerymen and they had the satisfaction of seeing the battery limbered up amid frantic cheers from the gunners amidships.
'We're too close inshore, sir. Bottom's shoaling.' Drinkwater turned to the ever-dutiful Hill who, while this fairground game was in progress, attended to the navigation of the ship.
'Bring her a point to starboard then.'
They were abeam of Wimereux now. Here too, there was a fort on the rocks at the water's edge, and below the fort two of the French invasion craft were stranded and going to pieces under the white of breakers. Drinkwater was suddenly aware that the cloud of powder smoke that rolled slowly ahead of the ship was obscuring his view. 'Cease fire! Cease fire!'
The smoke cleared with maddening slowness, but gradually it seemed to lift aside like a theatrical gauze, revealing a sight of confusion such as their own cannon could not achieve. They were less than two miles from Boulogne now, and under the cliffs and along the breakwaters of the harbour more than a dozen of the invasion barges lay wrecked with the sea breaking over them. Their shattered masts had fallen over their sides and men could be seen in the water around them.
