GEOLOGY IN MOTION: The Battle for Oil in WWII - Part 1 - European, African, and Middle Eastern Theatres

Geology and warfare have been closely linked throughout history. Geology can shape battles through the terrain, while other battles are fought for the terrain itself. Beyond serving as the objective and theatre of war, geology also provides essential natural resources that can drive conflicts. In the case of World War II, access to oil was a major factor. The availability, or lack thereof, of natural resources for each side, significantly influenced their military strategies and helped shape the war’s outcome. By the early 20th century, petroleum had evolved from a mere industrial resource into a crucial element of global geopolitics. World War I highlighted its strategic importance as mechanized warfare became increasingly reliant on oil for tanks, aircraft, and naval vessels. A pivotal moment came with the British Royal Navy’s shift from coal to oil fueled ships, implemented under Winston Churchill’s leadership as First Lord of the Admiralty, raising oil’s vital role in military operations (Yergin, 1991). Following World War I, the collapse of the Ottoman Empire allowed European powers—especially Britain and France—to take control of key Middle Eastern oil resources, particularly in present-day Iraq and Iran (Yergin, 1991). At the same time, the United States became the world’s leading oil producer, thanks to its vast domestic reserves. The Soviet Union emerged as a major oil power, boasting substantial reserves in the Caucasus region, especially in Baku, Grozny, and Maikop (Bellamy, 2007). In contrast, the future Axis powers including Germany, Italy, and Japan—faced significant challenges in securing reliable sources of petroleum. By the 1930s, Germany’s rearmament under Adolf Hitler highlighted a critical weakness: a lack of domestic petroleum reserves. Unlike the United States or Soviet Union, Germany was largely dependent on imported oil, particularly from Romania (Glantz & House, 1995). As World War II loomed, securing a stable and adequate oil supply became one of the Third Reich’s primary objectives.
