The wet sponge rule

The wet sponge rule was a technical protocol central to the operation of the electric chair at Cold Mountain Penitentiary, governing the conduct of executions on the Green Mile. Its purpose was to ensure that the electrical current passed efficiently through the condemned man's body, causing a rapid death. The rule's deliberate violation by guard Percy Wetmore during the execution of Eduard Delacroix produced one of the most harrowing and consequential events in the history of E Block, transforming a state-sanctioned killing into a prolonged atrocity that haunted every witness.

Purpose and Mechanism

The rule dictated that a circular piece of sponge, cut to fit precisely inside the metal cap placed on the condemned man's head, must be soaked in brine before each execution. The brine-saturated sponge acted as a conductor, channeling the direct-current electricity from the wire, through the cap, and directly into the brain. Paul Edgecombe, the block superintendent, explained that the sponge was kept in a galvanized tin bucket and soaked before use. During rehearsals, the sponge was not used; the cap was placed on the stand-in's head dry, but for the actual event, the wet sponge was essential. The rule was so fundamental that during the rehearsal for Arlen Bitterbuck's execution, Brutus Howell pressed a finger into the sponge, licked the tip to confirm it was wet, then returned it to the bucket, knowing it would be used only when the real execution took place. The sponge's function was to create an "electric bullet to the brain," as Jack Van Hay, the switch-room operator, explained to Percy Wetmore.

The Deliberate Violation

Percy Wetmore, resentful of being laughed at by Delacroix and seeking revenge, deliberately sabotaged the execution by using a dry sponge. During the execution of Eduard Delacroix on a hot, thundery night in October 1932, Percy, who had been placed in the prominent role of capping the condemned man, deviated from the established routine. Instead of bending over the bucket to retrieve the wet sponge and then placing it in the cap, he brought the cap to the sponge, partially blocking the view of the other guards. He then jammed the cap with the dry sponge onto Delacroix's head. Edgecombe realized the horror only when he saw that no water was running down Delacroix's cheeks from beneath the cap—a detail that should have been present if the sponge had been properly soaked. He understood in that instant that Percy had learned from Van Hay what the sponge was for and what would happen if it was dry.

Consequences of the Violation

The use of a dry sponge transformed the execution into a prolonged, agonizing death. Instead of a swift surge that would have rendered Delacroix unconscious, the current met high resistance, causing the sponge and the man's flesh to burn. The humming of the electricity wavered and was joined by a crackling sound. Smoke curled from beneath the cap and from the hole in its top. Delacroix began to jitter and twist, his legs pistoning, and he emitted choked howls of pain audible even over the roaring rain. The mask on his face burst into flame, his eyes were blown from their sockets, and his skin charred. The execution lasted at least two minutes, during which Delacroix was conscious and screaming. The witnesses panicked, one woman fainted, and the doctor collapsed. Afterward, Edgecombe noted that Percy had known exactly what he was doing; he had listened carefully when Van Hay explained how the brine-soaked sponge conducted the juice, channeling it into a kind of electric bullet to the brain. Percy later claimed he "didn't know the sponge was supposed to be wet," a lie he had rehearsed, but the evidence of his deliberate sabotage was clear to the guards who understood the rule.

Significance and Aftermath

The violation of the wet sponge rule became a turning point in the narrative, deepening the moral crisis for the guards and solidifying their determination to act against Percy. The botched execution was a direct result of Percy's cruelty and his desire to punish Delacroix for laughing at him. The rule itself, a simple technical precaution meant to ensure a humane death, was weaponized to inflict maximum suffering. The event underscored the guards' complicity in a system that allowed such cruelty, and it directly led to their risky plan to take John Coffey to heal Warden Moores's wife, an act of atonement for their part in Delacroix's "bad death." The rule's violation also demonstrated the profound danger of placing a man like Percy, who was mean, stupid, and connected to the governor, in a position of power during an execution. The wet sponge rule, in its breach, revealed the fragile line between state-sanctioned killing and outright torture.
