The Desert Chessboard explains the battlefield itself: Tobruk, the frontier, the escarpments, desert tracks, supply routes, ridges, and the deadly open spaces between them. The episode shows why the Western Desert was never truly empty, even when it looked open on a map. Small localities, airfields, passes, and lines of movement became critical because they shaped where tanks could advance, where infantry could hold, and where supply columns could survive. Crusader was fought across distance, dust, and uncertainty, and the ground itself became one of the campaign’s most important forces. Produced by Trackpads.com.
