The First World War: Blood in the Trenches (Part 1)

The companion piece to Part 2 — Holland and Sandbrook cover life in the trenches in 1915, the German spring offensives, and the introduction of poison gas on the Western Front. At 84 minutes this has room to breathe, moving from the experiential reality of trench warfare to the strategic escalation that defined the war's character. Well-paced and properly focused on the fighting rather than the politics.
