The development of artillery weapons has greatly changed over the centuries, from the first use of rock-hurling catapults of the Romans, to the invention of gunpowder in the 13th century, and eventually the creation of mortars, cannons, and rockets. Artillery usually describes howitzer cannons, rocket launchers, and mortars. This documentary, narrated by Oscar-winning actor George C. Scott, examines the history of artillery weapons using archival photographs and film. The program highlights their functions and impact during the course of war and profiles the men who developed and improved these weapons over the centuries, as well as the tactics and strategies employed to effectively use these artillery pieces in the fields of battles.
