Inaccessible Sevastopol. Circular defense

Continuation of the novel "Inaccessible Sevastopol. Defense core. "
Angerist veteran Alexei Leshchenko, who fell in the flaming 1941 right from the trenches of the Svetlodar arc of 2015, managed to make the unthinkable: thanks to his efforts as commander of the 35th armored battery, the city of Hero Sevastopol survived in the third, the most terrible assault who brought down his German General Manstein.
But the war has not yet been won-the Nazis are torn to the Volga, a bloody Battle of Stalingrad is tied, and the Italo-German squadron, headed by the Italian battleship Julio Cesare, is being tied through Bosphorus and Dardanella. And on shipyards in occupied Nikolaev, heavy gunboats are built for shelling Sevastopol.
Alexei will have to repel attacks on a fortified city not only with land, but also from the sea, to withstand enemy battleships and heavy cruisers!
