Let us, however, assume that Sangatte may conceivably have possessed a harbour in Caesar’s time. Even so, it is impossible to admit that Sangatte can have been the superior portus. For, if the eighteen ships which carried the cavalry had started from Sangatte, the conditions of wind and tide which would have rendered a voyage from Wissant to Kent less favourable than from Boulogne would obviously have been more unfavourable still.
3. There is one passage in Caesar’s narrative which, to a sailor, would be alone sufficient to prove that Wissant was not the port from which Caesar sailed in 55 B.C. We have seen that the gale which drove some of the cavalry transports from the point where they were first sighted westward down the coast carried the others back to the port from which they had started. I will assume that the latter were laid to on the port tack:[2846] if they could not work to windward, a glance at the map will show that they could not have returned to any point east of Wissant. The gale must obviously have blown from some point between the east and the north; and, if Caesar sailed from Wissant, the place from which the transports started must, as we have seen, have been Sangatte. Now it is absolutely incredible that a gale which drove some of these ships from a point near the South Foreland[2847] westward down the coast should have carried the others back to Sangatte. Caesar says that the former were ‘in great peril’, and that, when they anchored, the waves broke over them. A sailor would at once understand what their peril was. They were in no danger of being driven ashore; for while the gale was at its height they stood out to sea.[2848] They ran before the wind; and they were in danger either of broaching to or, possibly, of being ‘pooped’.[2849] From this we should conclude that the wind, when it struck the ships somewhere east or north-east of the South Foreland,[2850] blew from about the north-east: indeed, as the waves broke over the ships, it may have blown from north-east by east; for, if it had blown from the north-east or north-east by north, the ships, if they anchored close in shore, west of Folkestone, would have been in a sheltered position.[2851] The most easterly point at which they can be assumed to have been when they were caught by the gale is NW. 4° N. of Sangatte. Therefore if the wind had blown from the north-east, the ships that were carried back to the port from which they had started would have had to sail within less than eight points and a half of it in order to reach Sangatte. But, as Falconer[2852] says, a ship laid to in a gale makes from 5½ to 6½ points of lee-way. Reduce this estimate to four, and you will see that the transports would have had to lie within less than four points and a half of the wind in order to make Sangatte. No ancient ship could have done this. Close-hauled and under short canvas, as they would necessarily have been, the transports, as Commander Richmond remarked to me, would ‘just have sagged to leeward’. It may be objected that the tide would have helped them if it was running up the Channel. But the flood tide is almost neutralized by a north-easterly gale, and simply makes the sea more vicious: the ships would have moved so slowly that they could not have crossed the Channel in one tide; and when it turned and began to sweep them westward, their prospect of reaching Sangatte would have been more hopeless than ever. With a north-easterly gale, or even one which blew from north-east by north, it would have been absolutely impossible, so Commander Richmond and the harbour-master of Dover have separately and independently affirmed, for the vessels to fetch that anchorage.[2853]
4. Desjardins[2854] shows that, whereas four Roman roads, meeting at Gesoriacum, are mentioned in the itineraries,[2855] not a single Roman road led to Wissant. The advocates of Wissant have, indeed, replied that this proves nothing, since, in Caesar’s time, there were no Roman roads in any part of Gaul.[2856] But this reply is nugatory. Since no Roman roads led to Wissant, it is clear that if Wissant was the Portus Itius, this harbour, which Caesar had ascertained to be ‘the most convenient’ port of departure for Britain, was regarded by his successors as useless. Such a hypothesis is not tenable.
5. The mention of roads suggests another objection to Wissant. We have seen that Caesar’s army, consisting of five legions and 2,000 cavalry, remained weatherbound at the Portus Itius in 54 B.C. for about twenty-five days; and that with them were three other legions and 2,000 cavalry, who were left behind under the command of Labienus to guard the ports during Caesar’s absence.[2857] Thus for twenty-five days a force amounting to at least 32,000 men and 4,000 horses had to be fed; and of these not less than 12,500 men and 2,000 horses for about ten weeks more.[2858] No calculation is needed to show that these multitudes could not possibly have been supplied by the country in the neighbourhood of Wissant, even if it were as fertile as (according to Dr. Guest himself) it is ‘notoriously barren’.[2859] Their food must have come from a distance; and to transport it to Wissant without roads would have been a task of extreme difficulty. Dr. Guest assumes that Caesar’s fleet would have supplied his wants.[2860] But the fleet could only have procured grain from a port. Surely, then, Caesar would have found it most convenient to start from a port which was in communication by road or by river with the interior. Such a port was Boulogne, which enjoyed both these means of transit. What would have been gained by abandoning it for the isolated Wissant?
Again, it will be remembered that Labienus built sixty ships during Caesar’s absence in Britain;[2861] and we have seen that most of the modern advocates of Wissant admit that there was no harbour there, except the tiny creek formed by the ruisseau d’Herlan, or possibly a roadstead which may have been partially sheltered by the Banc de Laine. Not one of them has attempted to explain how Labienus could have found the means of building sixty ships upon an exposed beach. But let us admit that his genius could have improvised dockyards.[2862] Let us even admit that the harbour of Dr. Guest’s imagination did really exist. Still, sixty ships cannot be built without timber. How was all this timber to be brought to Wissant without roads and without a river? Even assuming that there was a Gallic road, it is doubtful whether Labienus could have impressed the amount of carriage necessary to transport the timber from the forests. But a few miles off at Boulogne the difficulty would have disappeared.[2863]
6. Another objection is so obvious that it must impress every candid inquirer. If Wissant was the Portus Itius, why was Wissant never once mentioned during the first millennium of our era? There is no evidence worthy of the name that it was used as a port before the year 1013.[2864] It is surely inexplicable that the port which Caesar regarded as the most convenient for his purpose should have been found so inconvenient or so superfluous by his successors that during the imperial epoch it fell into entire disuse. Wauters indeed retorts that if Wissant was eclipsed by Gesoriacum under the Empire, so was the Gallic town of Bibracte by the Gallo-Roman Augustodunum, and that, although the naval station was Gesoriacum, Wissant may have been a great commercial port.[2865] But he omits to explain how a great commercial port could have been left unnoticed by history, or how it could have existed without a river and roads to connect it with the interior. Nor is there any analogy between Wissant and Bibracte. The hill-fort of Bibracte gradually fell into disuse because when Gaul settled down under the Roman dominion it was no longer required.[2866]
7. Finally, Mariette[2867] argues that the mere name of Wissant, which, like the names of many other villages in the Boulonnais, is of German origin, proves that it was not founded before the fifth century, and consequently that there could have been no frequented harbour there in Caesar’s time.
It has now been demonstrated that Caesar did not sail from Wissant. That it was the point of departure of his first expedition is out of the question; for in that case the portus ulterior, from which the cavalry transports set sail, must have been Sangatte; and we have seen that they could not have returned to Sangatte when they were dispersed by the gale. The portus ulterior can only have been Ambleteuse; and therefore Caesar sailed in 55 B.C. from Boulogne. But nobody will believe that, having had experience of the advantages of Boulogne, he would have discarded it in favour of a place which, for his purpose, was in all respects inferior.
Nevertheless, to satisfy doubters, I shall state the case for and against Boulogne.
