The Gas Shell Gambit: Separation and Capture in the Trenches

In the labyrinthine trenches of Skaro, the Doctor, Sarah, and Harry stumble upon a macabre illusion of defense—corpses propped up as sentries—revealing the war’s desperate, cyclical nature. Their discovery of a locked service tunnel (potentially leading to Davros’s bunker) is abruptly interrupted when a gas shell explodes nearby, forcing them to scavenge respirators from the dead. As they struggle to survive the toxic attack, a ragtag militia ambushes them, only to be swiftly cut down by a disciplined Kaled military unit. The Doctor and Harry are captured and dragged away, while Sarah is left behind in the chaos, the smoke obscuring her fate. This brutal sequence fractures the group, thrusts the Doctor and Harry into Kaled custody, and leaves Sarah isolated—setting up her solo journey into the heart of the war’s horrors. The event underscores the war’s inhumanity, the Doctor’s vulnerability, and the mission’s escalating stakes as the Daleks’ genesis looms closer.

Decoy Corpses' Patchwork Uniforms

The corpses propped up as sentries serve as a grim illusion of defense, symbolizing the desperation of the war on Skaro. They are discovered by the Doctor, who notes their role in making the trenches appear fully manned. During the gas attack, the group scavenges respirators from these corpses, using them to survive the toxic fumes. The corpses thus transition from a symbolic element to a practical tool for survival, highlighting the war’s inhumanity and the lengths to which the characters must go to endure.

Gas Shell

The gas shell explodes nearby, unleashing poison gas that forces the Doctor, Sarah, and Harry to scavenge respirators from the corpses. This sudden threat disrupts their exploration of the service tunnel and creates chaos, during which the ragtag militia ambushes them.
