It is probable that the usual three "battles" were drawn up in line, each with its archers on the flanks and the dismounted men-at-arms in the centre; the archers being thrown forward in wedge-shaped salients, almost exactly as at Crecy.
To the north, Forts Salbert and Roppe form the salients of a long defensive line on high ground, at the centre of which, where the Savoureuse river divides it, a new work was added later.
The old fortress consisted of the town enceinte, the castle (situated on high ground and fortified by several concentric envelopes), and the entrenched camp, a hollow enclosed by continuous lines, the salients of which were the castle, Fort La Justice and Fort La Miotte.
Columns (a) and (b), forming the strongest part of the army, and also column (c) soon met with strong resistance (morning 22nd), and the country, the weather (stormy since the 20th) and tactical incidents making progress uneven, the front at nightfall of the 22nd was very sinuous, the Turks holding pronounced salients at Eski Polos, and .also at Almajik, while the Bulgarians had penetrated nearly to Kadikoi in the centre and within 2 m.
Continued pressure on the Kadikoi and Petra fronts forced the Turks to evacuate their salients, and at night the Bulgarian line, with its flanks somewhat advanced, ran roughly E.W.
