In fact, all the evidence is in favour of my first proposition, that the principal place of attack was at or near the Romanus Gate.
(2) It is undisputed that Top Capou (that is, Cannon Gate) was known in early times as the Gate of St. Romanus. It is mentioned under that name, for example, in the ‘Paschal Chronicle’ in the time of Heraclius, and again in the reign of Andronicus the First by Nicephorus Gregoras (ix. ch. 6), and as late as the middle of the fourteenth century by Cantacuzenus (p. 142, Ven. ed.).
(3 & 4) The evidence to show that the final assault was not at or near Top Capou is abundant.
Owing, however, to the constant mention of St. Romanus and the undoubted association of that name with Top Capou, it has been naturally assumed that the chief place of attack was at or near the latter Gate. Even Paspates was driven to disregard the evidence of his own eyes and to fix the assault on the steep part of the slope near Top Capou (Πολιορκία, p. 186).
But all observers who have studied the question on the spot, with the exception of Paspates, are now agreed that the chief place of assault was in the Lycus valley. In such case it necessarily follows that the name Romanus was given during the siege to some other gate than Top Capou.
The late Dr. Dethier was the first to suggest that the Gate spoken of by the contemporaries of the siege as St. Romanus was the Pempton. Let us examine the evidence. It is worthy of note that Phrantzes places Justiniani in the ‘region’ or district of the Romanus Gate. The Italian writers, knowing less of the city, say ‘at’ such Gate.
Now what was the Pempton? Each of the two Civil Gates on the landward side which we need here regard—namely, Top Capou and the Adrianople Gate—crowned a hill on one side of the Lycus valley and was exceptionally strong. They formed, in fact, with their towers and barbicans two of the strongest positions in the landward walls. The bridges across the foss opposite these and the other Civil Gates were intended to be broken down during a siege, and in fact were broken down when Mahomet’s siege commenced.[566] The Military Gates which led from the city to the Peribolos were then opened, though they were generally walled up in times of peace. The Pempton or Fifth Military Gate or Gate of the Fifth (for both forms of names are found) was the one which gave access to the Enclosure in the Lycus valley. It was known also in early times as the Gate of St. Kyriakè, from a neighbouring church, and as the Gate of Puseus from a Latin inscription still existing upon it, dating probably from the time of Leo the First, recording that Puseus had strengthened it.[567]
It is a remarkable fact that no writer who was either a witness of the siege or subsequently wrote upon it mentions the Pempton either under that name or by those of Kyriakè or Puseus. It is impossible to believe that it was not used. It was built for the express purpose of giving access to the troops into the Peribolos within which, beyond all doubt, the most important fighting took place. To admit that Justiniani and the soldiers under him were stationed between the Outer and the Inner Walls in this part and yet to suggest that the Pempton was not used is altogether unreasonable. Dethier’s suggestion is, that when the Civil Gates were closed people gave to the Military Gate the name of the nearest Civil Gate. Probably the earlier names given on account of their numbers were generally unknown. The latest instance I have found of the use of Pempton is in the ‘Paschal Chronicle.’
In support of this view it is important to note that many contemporaries speak of another place where the cannonading was severe as at the Pegè Gate (as, for example, Barbaro and Philelphus), whereas no one doubts that the present condition of the walls affords conclusive evidence that the writers intended to indicate Triton—that is, the Third Military Gate between the Pegè and the Rhegium Civil Gates.
The suggestion that the Pempton was commonly called the Romanus Gate explains various statements which are otherwise irreconcilable. We have seen that Ducas says that the sultan was encamped opposite the Chariseus Gate, while Phrantzes places him opposite the Romanus. Dr. Mordtmann urges[568] that from the small knoll where, according to Ducas and Critobulus, Mahomet’s tent was pitched, an observer might fairly describe its position as opposite either, but if the Pempton were called Romanus, such a suggestion would be much more plausible. Again, Barbaro, as already quoted, places the great gun opposite the San Romano Gate because this was the weakest gate of all the city. But on p. 18 he uses the same phrase in stating that the ‘Cressu’ or Chariseus was the weakest gate in all the city, the explanation being, I think, that as the Pempton was about midway between the Romanus and the Chariseus Civil Gates he heard it called indifferently by either name. Tetaldi, the Florentine soldier who was present at the siege, states that two hundred fathoms of Outer Wall were broken down during the last days. Now, although the Inner Wall was repaired by Mahomet[569] and continued fairly complete, no attempt appears to have been made to rebuild the Outer.[570] The spectator has little difficulty in distinguishing where the twelve hundred feet of Outer Wall of which Tetaldi speaks was destroyed. It was opposite the Pempton and, judging from the condition of the walls, certainly not opposite the present Top Capou. But the same writer says that it was ‘à la porte de Sainct Romain.’[571] The Moscovite or Slavic chronicler says that the great cannon were placed opposite the station of Justiniani ‘because the walls there were less solid and very low,’[572] a description which would not apply to those near Top Capou, but which, like all the descriptions given, does apply to the lower part of the Lycus valley. Here, in the phrase of Professor van Millingen, was the heel of Achilles, the Valley of Decision.[573] The weakness of this portion of the walls is illustrated by the fact that when Baldwin the Second expected an attack by Michael he walled up all the landward gates ‘except the single one near the streamlet where one sees the church of St. Kyriakè’—that is, except the Pempton.[574] In other words, the walls being there the weakest, it was anticipated that there would be the attack, and the entry into the Peribolos must be kept open to defend the Outer Wall. In the ‘Threnos’ the siege is described as being at the ‘Chariseus Gate,’ now St. Romanus, which is called Top Capou.[575] Apparently the confusion in this description is hopeless, but if the Pempton were called indifferently, as by Barbaro, Romanus and Chariseus, it becomes intelligible.[576]
