Introduction
In 1917, the United Kingdom and Bulgaria fought in the Battle of Doiran during World War I. The defense of Dobro Pole and Doiran was a formidable task for the weary Bulgarian soldiers and a crucial test of the tactical acumen and leadership abilities of the country’s top commanders. The battle victory is an ideal reference for analyzing the variables that affect decision-making and operational execution in wartime.
For example, the battle of Doiran was marked by stalemate and prolonged engagement, which significantly affected the morale and physical stamina of the troops and their leaders. In general, Bulgaria’s and its allies’ defeat was inevitable despite their spectacular military victories, such as the reoccupation of Dobrudja and the taking of Bucharest.
However, one man’s military prowess prevented its annexation and contributed to one of Bulgaria’s most triumphant victories. Major General Vladimir Vazov, the head of the Ninth Pleven Infantry Division, was that man (Vpandeliev, 2012). Therefore, this paper aims to provide a detailed analysis of the breakthrough achieved by Bulgaria and its allies, as well as General Vladimir Vazov’s victorious resistance at Doiran during the latter stages of World War I on the Macedonian Front.
The first campaign started in the spring of 1917 and continued until the end of the war in 1918. The British regiment attempted to storm the Doiran stronghold four times, misjudging the Bulgarians’ strength, and was defeated each time. The British hoped that a break on the Macedonian front would force German forces away from the Western Front. Contrary to their expectations, they suffered over 12,000 casualties while the Bulgarians suffered 2000(Vpandeliev, 2012).
The British dominated all Central Powers on all fronts, and events on the Western Front necessitated a new push to undermine their dominance. Following an extended battle, multiple outposts were captured, and the position was stormed. Without delay, General Vazov intervened by deploying backup forces into the conflict to establish contact with his outposts. The critical and last struggle for the Doiran position occurred on September 19 (Lau, 2016). The British, bolstered by backup forces, defended the recently captured outposts for five hours, but the Bulgarians ultimately overcame them and drove them back. The tally of casualties was grim on both sides, where the British forces suffered more casualties than the Bulgarians.
Tactical Intelligence of the Leaders
The Bulgarian infantry had taken defensive positions a couple of months before the British launched attacks on the Dorian front. They were led by Major General Stefan Nerezov and Colonel Vladimir Vazov, who would soon be promoted to General and take command of the troops(Vpandeliev, 2012). Vazov and the Bulgarian high command planned an all-out offensive against Salonika to drive all the allies out of Greece and close that front.
However, Germany’s high command disagreed with this tactical approach. They argued that this front needed to be kept open to divert Allied troops from the Western Front (Ivanov, 2012). The latter reasoning was understandable since the Allies were currently sending hundreds of thousands of men to Salonika (National Army Museum, n.d.). Since there would be no significant offensive, Vazov requested that Germany supply building materials, such as concrete.
The barriers constructed by Vazov’s men over the winter and spring were the most impressive defense line in the war. They included two new main positions with two rows of continuous trenches up to 2m deep, linked by communication passages (Ivanov, 2012; Lau, 2016). Additionally, the troops constructed a two-line barbed-wire system in front of the trenches (Lau, 2016).
Behind them were concrete galleries that could serve as firing positions for artillery or as ammunition platforms. The multiple barriers, including smaller fortifications in front of the primary position and little hills connected by a single trench, provide an advanced positioning for the Bulgarian troops. The advanced positions on the small hills were lightly manned but heavily armed with machine guns to halt attackers’ forward momentum and force them to get down long before they could reach the first line of trenches, leaving them vulnerable.
Vazov also ordered concrete bunkers built, some as deep as 70m underground (Ivanov, 2012). These were large enough to hold the entire 9th Division’s 34,000 men and protected against aerial attacks (Ivanov, 2012). Although the British had a small initial success during the attack, the barriers and the advanced positions helped the Bulgarians completely repulse the attacks (The Infographic Show, 2019). Therefore, the meticulous planning and wisdom of General Vazov played a crucial role in defeating the British despite having less firepower than the British army.
Well-Designed Trenches and Communication Means
Establishing two rows of continuous trenches offered a fallback efficiency for the Bulgarian soldiers. For instance, if one trench was overwhelmed, the fighters could retreat to the second defensive line, repulse the enemy advance, and retake the first trench in a counterattack (The Infographic Show, 2019). The trenches were connected by long passages narrow enough for one person to pass at a time, making them useless for the advancing British but facilitating this tactical retreat (Ivanov, 2012). Telephone wires across the linking tunnels allowed commanders to stay in contact and better organize the flow of supplies, reinforcements, and retreats. Communication efficiency was a breakthrough for the Bulgarians in the war, as their soldiers were well coordinated, alongside the tactical and landscape advantages.
The Bulgarian Intelligence Services
The British made significant gains two days into the war, but Bulgarian artillery forced their retreat at the end of the second day. To breach the Bulgarian defense, the British merged three infantry divisions and attached artillery, creating a force of 43,000 men (Ivanov, 2012). The plan would be to concentrate all this firepower along a very small front section and put maximum pressure on the Bulgarians.
Meanwhile, the Bulgarian intelligence services confirmed the British were amassing for a major attack and immediately reinforced the single division holding that front with 30,000 men and artillery. Acting on this intelligence promptly was a defining factor in the war for Bulgarians, as it reduced the ratio to almost 1 to 1, making it easier to counter the British (Vandeliev, 2012). The British may have outnumbered the Bulgarians at the Battle of Doiran, but as the defenders, the advantage lay firmly with the Bulgarians. When facing a heavily fortified enemy, attacking without at least a 3-to-1 advantage would be disastrous for the attacking force, as evidenced by the outcome of the Doiran battle.
Geographical Advantage and the Casualties
The countryside west of Lake Doiran was a terrain with hills, galleys, and ravines incorporated into a defensive system. Although the Bulgarians and Germans did massive work turning the landscape into a major stronghold, the geography of the Doiran area enabled them to construct the defense line. For instance, the peaks allowed Bulgarians to build their central observation posts, which overlooked all the British lines (The Infographic Show, 2019).
These physical landmarks already offered an advantage over the British troops because intelligence, surveillance, and planning could be conducted with greater accuracy. In the event of enemy penetration of the first defensive line, the northern ridge offered an ideal opportunity to effectively block the enemy’s access to the North, limiting his exploitation operations.
The geographical advantage enabled the Bulgarians to launch attacks with greater precision, resulting in higher British casualties. The high number of casualties was perhaps one of the primary reasons the British soldiers lost morale and retreated. For instance, they lost 12,000 killed, wounded, and captured, of which more than 2,250 were buried by the Bulgarian defenders (The Infographic Show, 2019). The heavy losses during the first and second attempts, with casualties, thwarted further attempts because the outcomes no longer favored the British.
Logistical Advantages
British Commitment on Multiple Fronts
The reinforcement the British needed to increase the advantage to at least 3 to 1 required moving troops from elsewhere to Doiran. It meant the British would have to bring forces from further North. However, an intense fight with the Germans prevented the reshuffling of such an army force(The Infographic Show, 2019). Reinforcing the Bulgarian assault might mean allowing the Germans a breakthrough elsewhere, which would be an impossible compromise. The inability to move troops played to the Bulgarians’ advantage, allowing them to sustain a more substantial fight.
Nearby Fresh Source of Food
In 1914, Bulgaria was a young nation, having only recently attained independence, and was still seeking ways to bring all its lands under its control. Bulgaria was worn out after two wars and was experiencing an economic crisis following the humiliating Treaty of Bucharest, which marked the end of the Second Balkan War and the loss of the wheat-producing Dobrudja (New Zealand History, n.d.; Vpandeliev, 2012). The Vazov set up farming communities behind the front lines and looked after soldiers to bring in crops and livestock. The strategy was ideal, given the shaky supply chain, and having a nearby source of fresh food helped him feed the army and boost morale.
Conclusion
The Bulgarian defenses in the Battle of Doiran were the best defense system of any nation in the First World War. General Vazov, through their tactical intelligence and experience, played a crucial role in planning and executing the tactical approach that helped his troops win the war. During the conflict, Vazov’s forces constructed an outstanding defense barrier that included trenches, barbed wire, and concrete galleries, all critical to effectively distinguishing and repelling the German army. Bulgarian soldiers deployed two continuous trenches as fallback positions, allowing them to retreat if overwhelmed and strike as needed.
Furthermore, telephone wires improved communication, allowing commanders to plan for supplies, reinforcements, and retreats more effectively, marking a significant milestone in the battle. Other elements that could have contributed to the triumph include the intelligence service, geography with hills, galleys, and ravines integrated into a defensive system, British commitment on other fronts, and the availability of fresh food. All these factors enabled the Bulgarians to sustain the fight, replenish their supplies, and gather accurate intelligence to launch precise and devastating attacks.
