What is now called Romney Marsh is the northern part of a vast plain, bounded on the east and south by the sea, and on the west and north by the line of heights at the foot of which the military canal has been cut. It is difficult to determine what was the aspect of Romney Marsh in the time of Cæsar. Nevertheless, the small elevation of the plain above the level of the sea, as well as the nature of the soil, lead us to conclude that the sea covered it formerly up to the foot of the heights of Lymne, except at least in the part called Dymchurch-Wall. This is a long tongue of land, on which are now raised three forts and nine batteries, and which, considering its height above the rest of the plain, has certainly never been covered by the sea. These facts appear to be confirmed by an ancient chart in the Cottonian collection in the British Museum.

Mr. Lewin appears to have represented as accurately as possible the appearance of Romney Marsh in the time of Cæsar, in the plate which accompanies his work. The part not covered by the sea extended, no doubt, as he represents it, from the bay of Romney to near Hythe, where it terminated in a bank of pebbles of considerable extent. But it appears to us that it would have been difficult for the Roman army to land on a bank of pebbles at the very foot of the rather steep heights of Lymne. Mr. Lewin places the Roman army, in the first expedition, at the foot of the heights, on the bank of pebbles itself, surrounded on almost all sides by the sea. In the second expedition, he supposes it to have been on the heights, at the village of Lymne; and, to explain how Cæsar joined his fleet to the camp by retrenchments common to both, he admits that this fleet was drawn on land as far as the slope of the heights, and shut up in a square space of 300 mètres each side, because we find there the ruins of an ancient castle called Stutfall Castle. All this is hardly admissible.

Word for word, this expression signifies that the ships set sail four days after the arrival of the Romans in England. The Latin language often employed the ordinal number instead of the cardinal number. Thus, the historian Eutropius says, “Carthage was destroyed 700 years after it was founded, Carthago septingentesimo anno quam condita erat deleta est.” Are we, in the phrase, post diem quartum, to reckon the day of the arrival? – Virgil says, speaking of the seventeenth day, septima post decimam. – Cicero uses the expression post sexennium in the sense of six years. It is evident that Virgil counts seven days after the tenth. If the tenth was comprised in this number, the expression septima post decimam would signify simply the sixteenth day. On his part, Cicero understands clearly the six years as a lapse of time which was to pass, starting from the moment in which he speaks. Thus, the post diem quartum of Cæsar must be understood in the sense of four days accomplished, without reckoning the day of landing.

We must now go back to the fourteenth day before the full moon, that is, to the 17th of August, 699, to find a day on which high tide took place at Dover towards midday.

384

Mr. Lewin has stated that the country between Deal and Sandwich produces no wheat. This assertion is tolerably true for the tongue of marshy land which separates those two localities; but what does it signify, since wheat grows in great quantities in all the part of the county of Kent situated to the west of the coast which extends from the South Foreland to Deal and Sandwich?

385

It is almost impossible to fix with certainty the day when Cæsar quitted Britain; we know only that it was a short time before the equinox (propinqua die æquinoxii), which, according to the calculations of M. Le Verrier, fell on the 26th of September, and that the fleet started a little after midnight. If we admit a passage of nine hours, with a favorable wind (ipse idoneam tempestatem nactus), as on the return of the second expedition, Cæsar would have arrived at Boulogne towards nine o’clock in the morning. As the fleet could not enter the port until the tide was in, it is sufficient, to know approximatively the date of Cæsar’s return, to seek what day in the month of September, 699, there was high tide at that hour at Bolougne. Now, in this port, the tide is always at its height towards nine o’clock in the morning two or three days before full moon and before new moon; therefore, since the full moon of the month of September, 699, took place on the 14th, it must have been about the 11th or 12th of September that Cæsar returned to Gaul. As to the two ships which were driven farther down, Mr. Lewin (Invasion of Britain by J. Cæsar) explains this accident in a very judicious manner. He states that we read in the tide-tables of the English Admiralty the following recommendation: “In approaching Boulogne when the tide is flowing in, great attention must be paid, because the current, which, on the English side, drags a ship towards the east, on the Boulogne side drags them, on the contrary, towards the Somme.” Nothing, then, is more natural than that the two Roman transport ships should be driven ashore to the south of Boulogne.

“It was there (the mouth of the Seine) that Cæsar established his naval arsenal, when he passed over to that island (Britain.)” (Strabo, II. 160.)

388

The Meldæ dwelt on the Marne, in the country around Meaux; and as we have seen, according to Strabo, that Cæsar had established his naval arsenal at the mouth of the Seine, there is nothing extraordinary in the circumstance that some of the ships were built near Meaux. But it is not reasonable to suppose, with some writers, that the Meldæ dwelt at the mouth of the Scheldt, and believe that Cæsar had left important shipyards in an enemy’s country, and out of reach of protection.

389

The five legions which Cæsar led into Britain made, at about 5,000 men each, 25,000 men. There were, in addition to these, 2,000 cavalry. If we suppose, as in the first expedition, twenty-five horses per ship, it would require eighty to contain the cavalry. In the preceding year, eighty transport ships had been sufficient for two legions, without baggage – 200 ought to have been enough for five legions; but as the “Commentaries” give us to understand that those vessels were narrower, and that the troops had their baggage, it may be believed that they required double the number of ships, that is, 400, for the transport of the five legions, which would make about sixty-two men in a ship. There would remain 160 transport ships for the Gaulish and Roman chiefs, the valets, and the provisions. The twenty-eight galleys were, no doubt, the true ships of war, destined to protect the fleet and the landing.

390

According to a passage in the “Commentaries” (Book V. 26), there was in the Roman army a body of Spanish cavalry.

This appears to us to be evident, since we shall see subsequently Cæsar inclosed his fleet within the retrenchments contiguous to his camp.

394

As in the first expedition the disaster which happened to his fleet must have proved to Cæsar the danger to which the vessels were exposed on the coast, the above reflection indicates that, in his second expedition, he chose a better anchorage, at a few kilomètres farther to the north.

395

Ten cohorts formed a legion; but Cæsar does not employ this last expression, because, no doubt, he drew from each of his legions two cohorts, which he left for the guard of the camp. In this manner he preserved the tactical number of five legions, which was more advantageous, and caused each legion to participate in the honour of combating.

396

If from the sea-shore, near Deal, where we suppose that the Romans established their camp, we describe, with a radius of twelve miles, an arc of a circle, we cut towards the west, the villages of Kingston and Barham, and more to the north, the village of Littlebourne, a stream called the Little Stour, which rises near Lyminge, flows from south to north across a rather irregular country, and falls into the
