bomber Geschwader. Naval support came from the Italian 101st Squadron under Francesco Mimbelli. It consisted of four motor torpedo boats, five explosive motorboats, six CB class midget submarines, and a number of 35-ton coastal submarines and MAS boats. This force was the only Axis naval force deployed during the siege. Although Bulgaria was not technically at war with the Soviet Union, its naval staff worked closely with the Wehrmacht, and despite not being committed to combat, they provided bases for the Axis naval command (Admiral Schwarzes Meer, Admiral of the Black Sea) to operate in the waters of the Black Sea.

The Black Sea Fleet sent 49,372 personnel to fight as infantry. Most were not trained for ground combat, and the act was an ad hoc emergency measure. The naval brigades formed had four to six battalions of 4,000 men, allowing them to absorb significant losses. These forces were well armed, having a variety of artillery and mortar battalions. Almost 20 percent of the Coastal Army were naval personnel. In the Separate Coastal Army, the strongest divisions were the 95th, 109th, 172nd, and 388th Rifle Divisions. They each had around 7,000 soldiers, the rest of the Red Army units
