The defence of the Aegean seacoast during World War I

 

 

The Aegean Unit of the Bulgarian Fleet was established on 31 December 1914 with Decree N. 96. The Fleet Order fixed its organization and its task. It was composed by command, sea defence, semaphore observation service and workshop. Its main task was to assure the surveillance and the protection of the seacoast without craft.

The head of the Unit was maj. Nikola Furnadzhiev, who had been previously the head of the semaphore posts, with 1st rank midshipman Velizar Peev as adjutant and Lt. Georgi Antonov as head of the mine defence. The peace establishment was only 74 men, whom 8 assigned to the direction of the unit, 38 to the mine defence, and 28 to the semaphore observation service. They had only four rowboats, three at Dedeagach and one at Porto Lagos.

After the mobilization, proclaimed on 10 September 1915, the Aegean Unit reached its war strength, and on 20 September it was composed by 2 Staff officers, 5 senior officers and 237 NCOs and seamen. Its naval equipment was reinforced with the Iskra motor boat, weighting only 12 tons, and five rowboats. On 1 October, when Bulgaria entered war, the defence of the coast of the Aegean Sea was assigned to some units of the 10th Belomorska Division : 37th Infantry regiment at Ksanti, 40th infantry regiment at Dedeagach, and 8th cavalry regiment. They were supported by a little number of old guns taken from Sofiyski fortress artillery regiment (4 – 57mm Gruson guns and 18 – 75mm and 87mm Krupp guns). The harbour and the mine companies of the Aegean Unit were put under the orders of the units to cooperate with the Army to repel an enemy landing. On 10 October 1915 to protect the coastline 4 – 120mm L/25 guns of the Sofiyski fortress artillery regiment were sent to Dedeagach.

To protect the Bay of Dedeagach at the beginning of March 1916 the mine company laid down three rows of 10 mines each at distance of 10 km from the coast. In August 22 mines were laid down to defend the Bay of Porto Lagos. With the help of a German mine command of 33 men, the mine laying continued in 1917, especially after the intense naval bombardments of Kavala and Leftera made by the Anglo-French Fleet at the beginning of the year. From 24 to 29 March 1917 three rows of mines were laid down in the Bay of Kavala, while on 1 April the minefield at Dedeagach and Porto Lagos was strengthened. Finally on 14 and 23 April further mines were laid down in the Bay of Porto Lagos and Kavala. The main effect of the activity of the mine company was the great decrease of the traffic of the enemy ships along the Bulgarian coast.

 

After the victorious offensive of the 2nd Army in Thrace and the occupation of the Greek coast up to Kavala, the area assigned to the Aegean Units increased greatly. Since there were no coast guns to defend the coast of the Aegean Sea, it was necessary to turn to the fortress artillery, using also some guns captured in Greek Thracian fortress. On 20 August 1916 the operative order N. 59 of the 2nd Army commander mentioned 2 – 150mm batteries with 2 guns each of the Kavala coast artillery regiment. Unfortunately neither the number, nor the model of these guns is reported. On 10 May 1917 west of the Maritza river, between Dedeagatch and Makri were deployed :

    at Dedeagach : 2 batteries with 2 – 57mm Gruson guns each; 2 batteries with 2 and 4 – 87mm Krupp field guns respectively; 1 battery with 4 – 120 mm L/25 Krupp guns; 1 battery with 4 – 120mm L/28 Schneider-Canet guns;

    east of Makri : 1 - 87mm Krupp gun;

    at Cap Makri : 1 - 87mm Krupp gun;

    west of Makri : 2 batteries with 2 – 87mm Krupp guns each.

 

The coast artillery was constantly strengthened during the war, and in 1918 most of the 312 guns of Bulgarian 4th Army were used for coast defence (according with Stefan Noikov, the Belomorska Otbrana alone had 97 guns).

The head of the coast artillery of the Aegean Sea was col. Yerotey Sirmanov, who had been the head of the artillery of the 11th Infantry Division during the Balkan Wars, taking part in the siege of Odrin. With the establishment of the 4th Army, he became the head of its artillery, after having been promoted major general.
