2025 Symposium at the National WWI Museum and Memorial in Kansas City, USA, hosted online and in-person.

Riflemen “going over the top” is the iconic battle image of World War I.

But as large armies fought for mere meters of dirt and mud along the Western Front, strategists increasingly turned to finding other ways to gain advantages over enemies. WWI veteran and British military theorist B. H. Liddell Hart advanced the idea of an “indirect approach” in battle. Aviation technology, tunneling and mining, proxy fighters, insurgents and spies – these all achieved flexibility and surprised the enemy.

Explore the wide variety of battle strategies beyond trenches, including:

  • Diplomatic, economic and information warfare
  • Proxy forces and irregular warfare in the Age of Empire
  • New technologies: aviation, tunneling and mining
  • Maritime operations in support of land forces
  • Environmental and geographic considerations
