Battlefield is an American documentary series that debuted in 1994 on PBS that explores the most important battles fought primarily during the Second World War and the Vietnam War. The series employs a novel approach in which history is described by detailed accounts of major battles together with background and contextual information. The sixth and final series of the program was broadcast in 2002. The series provides a comprehensive narrative of the war; in addition to traditional tactical details, subjects such as personalities and motivations of the leaders, technological developments, management of war economies, strategic contributions of smaller battles, etc. are explored in terms of their contribution to particular turning points. The narrator (Tim Pigott-Smith) speaks throughout the series, seasons 1, 2, and 4, with no interviews of actual battle veterans. The show is entirely made up of archive footage and 3D graphics. Rare archive film, including rare colour footage specific to each battle is included. Battlefield presents a detailed analysis of the battle including leaders, commanders, soldiers and weapons. The show describes the events preceding the featured battle as well as details about its aftermath. The show also goes in depth to explain the political and military situation leading up to each battle, details about relevant weapons and tactics, analysis of the battle's cause, and its context in the war as a whole-all while using informative maps and graphical depictions of relative strength of the respective forces and their movements during the battle in question.
