🔰 Discover the history of Aden through rare photographs, maps, and historical documents (1839–1967).
During World War I (1914–1918), Aden held critical strategic importance as a fortified British coaling station and naval base guarding the Red Sea route to India and the Suez Canal.
1. Strategic Role & Defense
Guarding the Sea Lanes: Aden was the primary refueling and communications link between the Mediterranean, the Persian Gulf, and British India.
Command Structure: Operations were under the Aden Field Force (AFF), led by the Commander-in-Chief of the Bombay Army and later integrated into British Middle East command structures.
2. The Ottoman Invasion & The Siege of Lahej (1915)
July 1915 Advance: Ottoman forces under General Said Pasha, supported by allied Arab tribes, launched an offensive south from Yemen (then an Ottoman province) into the Aden Protectorate.
Battle of Lahej: Ottoman forces captured Lahej (Sultanate of Lahej), forcing the British garrison to fall back.
The Sheikh Othman Defense Line: British and Indian troops established a heavily fortified defensive line at Sheikh Othman and across the Khormaksar Isthmus, preventing Ottoman forces from penetrating into Crater or Steamer Point.
3. Military Units Deployed
Indian Army Regiments: The garrison was heavily manned by Indian Army infantry and cavalry units, including the 26th King George's Own Light Cavalry, 109th Infantry, and 51st Sikhs.
Royal Navy & Patrols: The Red Sea Patrol operated out of Steamer Point to enforce blockades along the Yemeni coast and intercept enemy movements across the Bab-el-Mandeb.
4. The Stalemate (1915–1918)
For most of the war, a stalemate existed along the Sheikh Othman perimeter. British forces held the Aden Peninsula and the immediate hinterland, while Ottoman forces controlled Lahej and the interior until the Armistice of Mudros in November 1918.

During World War II (1939–1945), the port city of Aden played a vital strategic role in the defence of Allied shipping routes across the Middle East and the Indian Ocean. At that time, Aden was a British-controlled territory and an important naval and commercial port located at the entrance to the Red Sea.
Because of its strategic location between Europe, Africa, and Asia, Aden became one of the most important military and logistical bases in the region during the war.
The geographical position of Aden made it a critical point for controlling maritime routes between the Mediterranean Sea and the Indian Ocean. Ships traveling through the Suez Canal often passed near Aden on their way to India, East Africa, and the Far East.
During the war, protecting these shipping lanes became essential for the Allied war effort. As a result, the British government strengthened the military presence in Aden and transformed the port into a major supply and defence centre.
Throughout the war, Aden served as an important base for the Royal Navy and the Royal Air Force. Naval vessels used the harbour for refuelling, repairs, and resupply before continuing their missions across the Red Sea and the Indian Ocean.
Military airfields were also established near Aden to support aerial patrols and reconnaissance missions aimed at protecting Allied shipping from enemy submarines and surface raiders.
The port facilities were expanded during the war to accommodate the increased number of ships and military personnel operating in the region.
A major responsibility of the forces stationed in Aden was the protection of merchant ships traveling through the Red Sea. These ships carried essential supplies, including fuel, food, military equipment, and raw materials needed for the Allied war effort.
Convoys of merchant vessels were organized and escorted by naval ships to ensure safe passage through potentially dangerous waters. Aden became a key staging point for these convoy operations.
The port also served as a logistical centre for Allied military operations in nearby regions. Supplies and personnel moving between India, East Africa, and the Middle East frequently passed through Aden.
Large quantities of fuel, ammunition, and equipment were stored in depots near the port and distributed to Allied forces operating across the region.
Despite the strong military presence, civilian life in Aden continued during the war years. The port remained active with commercial trade, and the city's diverse population included merchants, workers, sailors, and military personnel from many different countries.
However, wartime conditions brought increased security measures, military patrols, and restrictions in certain areas of the city.
During World War II, Aden became one of the region's most important strategic ports. Its location at the entrance to the Red Sea allowed Allied forces to protect vital maritime routes linking Europe, Africa, and Asia.
Military bases, naval operations, and convoy protection efforts centered in Aden helped the Allies maintain control of key shipping lanes throughout the war.
The war brought increased military activity to Aden. Soldiers, aircraft, and naval ships regularly passed through the port, turning the city into a bustling wartime hub.
After the war ended in 1945, Aden continued to play an important role in regional trade and international shipping.
