But there were points in the position which rendered the attack more difficult than might have been expected. The first was that any approaches directed against this front would be exposed to a flanking fire from the forts on the Capuchin heights, especially from the Calvary and Chapter redoubts. The second was that the greater part of the weak sections of the wall were within a re-entering angle; for the tower of Santa Lucia and the ‘Redoubt of the Germans’ by the Gironella project, and the curtains between them are in a receding sweep of the enceinte. Attacks on these ill-fortified sections would be outflanked and enfiladed by the two stronger works. The only exposed part of the curtain was that called Santa Lucia, running from the tower of that name down to the bastion of Santa Maria. Lastly, the parallels which the French might construct from their base on Monjuich would have to be built on a down slope, overlooked by loftier ground, and when they reached the foot of the walls they would be in a sort of gulley or bottom, into which the defenders of the city could look down from above. The only point from which the north end of Gerona could be approached from flat ground and without disadvantages of slope, is the short front of less than 200 yards breadth between the foot of Monjuich and the bank of the Ter. Here, in the ruins of the suburb of Pedret, there was plenty of cover, a soil easy to work, and a level terrain as far as the foot of the Santa Maria bastion. The engineers of the besieging army selected three sections of wall as their objective. The first was the ‘Redoubt of the Germans’ and the tower of La Gironella, the highest and most commanding works in this part of the enceinte: once established in these, they could overlook and dominate the whole city. The other points of attack were chosen for the opposite reason--because they were intrinsically weak in themselves, not because they were important or dominating parts of the defences. The curtain of Santa Lucia in particular seemed to invite attack, as being in a salient angle, unprotected by flanking fire, and destitute of any artillery of its own.
