First Use of Tanks: Battle of Flers-Courcelette (September 15-22)
On September 15, 1916, during the Battle of Flers-Courcelette, the British Army introduced the tank to the battlefield for the first time in history. Forty-nine Mark I tanks were deployed, though many broke down or became stuck. Despite their limited immediate impact on the overall battle, their appearance marked a significant technological milestone, foreshadowing future armored warfare. The objective was to capture key villages and positions held by the Germans. -
Battle of Thiepval Ridge (September 26-29)
A crucial part of the broader Somme offensive, the Battle of Thiepval Ridge took place from September 26 to 29, 1916, in the Somme region of France. The Allies' primary objective was to seize the high ground strongly held by the Germans between the villages of Thiepval and Courcelette. This battle saw heavy fighting and ultimately resulted in the capture of Thiepval village, a significant German stronghold, by the British. -
Other Somme Engagements
Throughout the month, numerous smaller but equally fierce engagements occurred as part of the Somme offensive, including the Battle of Morval (September 25-28), which saw further Allied advances, and the Battle of Combles (September 25-28), where British and French forces linked up to capture the strategically important town.
Eastern Front Developments
On the Eastern Front, the massive Russian Brusilov Offensive, which had begun in June, continued to exert pressure on the Central Powers. While its initial momentum had slowed, it still tied up significant German and Austro-Hungarian forces. Fierce fighting continued in Galicia and the Carpathians as Russia sought to exploit its earlier successes.
Romania Enters the Fray
After declaring war on Austria-Hungary in late August, Romania became a new theater of conflict. In September, Romanian forces advanced into Transylvania, facing immediate counter-attacks from German and Austro-Hungarian forces. This new front stretched the resources of the Central Powers further, but Romania quickly found itself in a precarious position.
Macedonian Front Offensive
In the Balkans, the Allies launched a major offensive on the Macedonian (Salonika) Front. This offensive, aimed at breaking the deadlock against Bulgarian and German forces, included the Battle of Monastir, which began in September and would continue for several months. The goal was to relieve pressure on Romania and pin down Central Power forces in the region.

Broader Context and Impact
September 1916 underscored the attritional nature of World War I. While new technologies like tanks were introduced, they did not immediately break the stalemate. The fighting on the Somme continued to incur massive casualties for relatively limited territorial gains. The opening of the Romanian Front, while initially promising for the Allies, quickly became a drain on resources as the Central Powers responded decisively. Overall, September was a month of intense, costly, and largely indecisive fighting that continued to shape the brutal landscape of the First World War.
