... the middle of the curtain wall between Bastions VI and VII. At the time of the Duchy of Warsaw in 1807 a caponier was built here – a small building from which it was possible to fire in the direction of the road located along to outer line of the moat, the so-called covered way. In front of the road a modern structure called a
ravelin* was made; it was a triangular earthen structure protecting the curtain wall between bastions. The ravelin protruded far away from the walls and into the moat. It assumed the form of the so-called
lunette*. It had powerful embankment in front but in the rear, i.e. on the side of the fortress, it was open. In 1825 Russians intended to place inside the lunette a large
reduit*, a triangular structure covered with thick earthwork with firing posts but they never did. Time passed and the structure was not there in spite of the fact that it was included in the beautiful and perfectly drawn plan of Colonel Berezowski dating from 1847. It was only in 1854 that frantic works started in the face of a potential military conflict with Austria and an imminent Polish national uprising. The Crimean War was going on and the Habsburg Monarchy could stand on the side of Turkey, England and France. The remodelled lunette became the most modern facility in the fortress. Its external earthworks were provided with powerful earthen traverses*, which efficiently defended artillery positions. Earthen
redoubt*, in spite of being deprived of masonry casemates, was an elevated infantry position and possibly, that of howitzers. In the second half of the 19th century, after the fortress was demolished, Cossack military barracks were built at the site of the levelled redoubt. Russians were also planning to build another masonry redoubt performing the function of a
caponier* at the site of a Polish structure standing on the expanded part of the covered way to defend the rear area of the lunette and provide a possibility for protecting the covered road with enfilading fire. They even prepared a slightly elevated area where there is a vantage point but they never actually built the redoubt. However, Captain Engineer Jan Paweł Lelewel “portrayed” the planned building in one of his excellent watercolours. It was just a prophetic vision; the only thing that was actually built at the site was a wooden
blockhouse* whose size did not exceed toady’s news-stands. Obviously, Russians put off expansion of external structures of the fortress. In the memorable 1854 they made quickly a small, triangular redoubt I in front of the huge lunette described above. No trace of it has been preserved - houses have been built at the site.
