• The Battle of Doiran 1917 was a battle in World War I between the United Kingdom and Bulgaria. Planning During the Second conference of the Military Counsel of the Entente in Chantilly, it was decided to continue with the attempts at a breakthrough. The task for the Entente forces on the Macedonian Front was to inflict major defeats on the Bulgarian army and effect a wide breakthrough in the Balkans in a relatively short time. The Allied command, which expected reinforcements, planned a major assault in the direction of Vardar and Doiran. In 1917 the 2nd (Bulgarian) Thracian Infantry Division was replaced at Doiran by the 9th Pleven Infantry division under the command of Colonel Vladimir Vazov. Initial attacks On 9 and 10 February the Allies attacked the 33rd Svishtov and 34th Troyan Regiments but were repulsed by a decisive counter-attack by the Troyan Regiment. The British advance on 21 February was repulsed by Bulgarian artillery after a two-day battle.[3] The Allied command found that the Bulgarian positions were better fortified than in the previous year, so it ordered a systematic artillery barrage on these defences. In the meantime, it continued the development of their forming-up ground which was 800 - 1,500 m from the defensive lines of the Pleven Division. To make the breakthrough, the British concentrated three divisions (the 22nd, 26th, 60th), with its artillery - more than 43,000 men, 160 guns, 110 mortars and 440 machine-guns. The objective did not differ much from the battle in the previous year, the main blow was on a front of 5–6 km towards Kalatepe.[4] The prognosis of the Bulgarian command for a major Allied offensive was confirmed by intelligence. The 9th Pleven Division was reinforced and had a total of 30,000 men, 147 guns, 35 mortars, 130 machine-guns. According to the orders of the High Command the front was divided into three zones with different widths: the right from the River Vardar to the Varovita heights with a width of 13 km, was defended by 1st Brigade (6 companies with 48 guns, 12 mortars and 56 machine guns); the central from the Varovita heights to the Karakondzho heights, 4 km wide, defended by the 57th Regiment (3 companies) and the left from the Karakondzho heights to Lake Doiran, 9 km wide, defended by 2nd Brigade (6 companies, 76 guns, 19 mortars and 52 machine-guns).[4] Defensive positions The Macedonian Front in 1916-1917. In 1917 the Bulgarian defensive positions and fortifications were further improved. It included two main positions with two rows of continuous trenches 1,5 – 2 metres deep, 200 to 1000 m apart and linked with passages for communication. In front of these positions there was a two line system of wire entanglements. Between the rows of trenches watch points, shelters, machine-gun nests and sunken batteries were constructed. Behind these defences there were concrete galleries, fire positions for the artillery and platforms for ammunition. In front of the main position there were smaller fortifications, with a partly constructed secondary position 2 – 5 km to its rear. The battle The battle for a breakthrough in the Bulgarian positions began on 22 April and continued intermittently until 9 May 1917. The assault began with a bitter four-day artillery barrage in which the British fired about 100,000 shells. As a result, the earthworks and some wooden structures in the front positions were destroyed. The Bulgarians also opened fire from the batteries between Vardar and Doiran. Vladimir Vazov ordered fire day and night on the Allied positions.[5] The initial several-hour struggle between the British and Bulgarian batteries was followed by a one-hour Bulgarian counter-barrage in which 10,000 shells were fired. Vladimir Vazov was a prominent General. His successful defence of Doiran made him a hero to the Bulgarians. The British infantry began its attack on the night of 24–25 April - 12 companies attacked the Bulgarian 2nd Brigade and after a bloody fight managed to take the
