The failure of Bridge Four’s side-carry tactic occurs during a bridge assault in which Kaladin attempts to turn the bridge itself from an instrument of exposure into a shield. The maneuver protects his crew with striking success, but its wider effect is disastrous: the bridges reach the chasm at different speeds, the Alethi archers lose a coherent target pattern, and the cavalry charge cannot begin as planned. The episode therefore makes a sharp distinction between local survival and operational success. Kaladin saves Bridge Four from the immediate volley while undermining the battle formation that Sadeas’s army depends upon.

Causes and Background

The tactic arises from the brutal logic of Torol Sadeas’s bridge system. Sadeas deliberately uses unarmored bridgemen as bait, arguing that the Parshendi are drawn to exposed crews and will therefore fire less heavily at soldiers and horses. His method depends on sacrificing several bridge crews during each assault while preserving the army’s more valued fighters. The bridge is not treated as equipment carried by soldiers but as a weaponized burden assigned to men whose lives the command structure has already priced cheaply.

Bridge Four’s danger becomes especially acute when the crew has been reduced to thirty members. Earlier losses could be absorbed because a bridge crew retained enough people to keep moving after four or five men fell. With so little margin remaining, another four or five deaths could make the bridge wobble or topple, inviting the Parshendi to concentrate their arrows. Kaladin estimates that the run could cost fifteen or twenty lives, and the decision to improvise follows from that immediate arithmetic of survival rather than from a general desire to alter the army’s strategy.

Kaladin proposes moving ahead of the other bridges and carrying Bridge Four on its side. The arrangement allows the wooden structure to intercept arrows while the crew runs beside it. He tells Teft that the plan may fail and that he will be the first to die because he intends to lead from the front. If he falls, the others are to return to the practiced shoulder-carry method. His willingness to place himself at the point of greatest danger gives the maneuver a moral force absent from Sadeas’s system: the leader shares the risk instead of assigning it exclusively to the lowest-ranked men.

The Maneuver and Its Immediate Success

Bridge Four charges after turning the bridge on its side. The shorter men form a line beneath the structure while the taller men bunch behind them, reaching through or upward to steady the bridge. Practice and endurance allow the crew to move faster than the other bridges despite the awkward load. Kaladin leads them ahead of the formation and angles slightly to the right, making the crew appear to be drifting off course.

The Parshendi archers kneel and prepare their volley. At the crucial moment, Kaladin turns sharply left, presenting the broad face of the bridge toward the archers. The arrows strike the wood, snap against it, or rattle against the stone. He then turns the bridge again, exposing the men and provoking the Parshendi to ready another volley, before using the structure as cover once more. The tactic exploits the interval between volleys: the crew runs exposed only while the archers are drawing, then places the bridge between itself and the next storm of arrows.

The immediate result is extraordinary for the crew but grim for everyone around it. Bridge Four reaches the chasm on mark, and no member is wounded. Other crews do not fare nearly as well. Bridge Seven is cut down row by row before its bridge crashes onto the stones; Bridge Twenty-seven begins to waver; Bridge Six reaches the chasm with more than half its members lost; and several other bridges have already fallen. The contrast reveals the tactic’s power as a protective device. Against the direct threat of the arrows, the side carry works.

Operational Failure

The maneuver fails because the assault is not merely a race to place individual bridges. The bridges must arrive in an aligned, unbroken sequence so that the heavy cavalry can cross in a coordinated charge. By running ahead, Bridge Four creates a gap in the timing of the assault. Other crews see how Kaladin uses the bridge as a shield and attempt to copy him, but they lack a common pace and do not coordinate their movements. Some stumble, while others try to lower their bridges for protection even as their companions continue forward.

The improvised defense consequently produces a fragmented battlefield. Each crew moves at a different speed, and the Alethi archers can no longer tell where to concentrate their volleys in order to soften the Parshendi before the bridge landings. Kaladin’s bridge is placed successfully, but when he orders the crew to pull back, the cavalry does not come. The heavy cavalry has been cut off, and without an unbroken line the charge cannot function. Its force depends not only on physical access across the chasms but also on the intimidation created by a massed, continuous advance.

This is the event’s central reversal. Kaladin’s plan changes the value of the scene from near-certain death for Bridge Four to immediate survival, then reverses again when that success damages the larger assault. His tactic is neither simply foolish nor simply triumphant. It solves the problem he can see—the slaughter of his own men—but exposes the incompatible demands placed upon him: protect bridgemen as human beings or preserve a battle plan built on their expendability. The maneuver fails at the level of army coordination precisely because it succeeds at making the bridge crew less disposable.

Repercussions and Punishment

Kaladin recognizes the consequences before anyone else celebrates them. Rock praises the fact that no one has been wounded, and Moash declares that Kaladin has changed bridge runs forever. Kaladin instead understands that he has completely undermined the assault. Because many bridgemen had a clear view of Bridge Four’s method, the innovation has spread across the formation without passing through the army’s chain of command. He expects repercussions once the generals and captains finish revising their plans, but the danger arrives almost immediately.

Gaz and Lamaril approach with reserve spearmen. Kaladin realizes that the officers may attempt to conceal their own responsibility by making the maneuver appear to have been Lamaril’s idea or by punishing the person who acted without authorization. He points out that Lamaril did not stop him and that soldiers saw Gaz speaking with the lighteyed officer. Lamaril responds by ordering that Kaladin be beaten but not killed, then withdraws toward the Alethi reserve lines. The command converts a tactical dispute into disciplinary violence and preserves the hierarchy that allowed the assault to use bridgemen as bait in the first place.

The beating is accompanied by the destruction of Kaladin’s limited resources. A spear butt knocks him down, soldiers kick him, and one boot tears open his belt pouch. His spheres scatter over the stones; they have lost their Stormlight and are now dull. The scene makes punishment material as well as physical. Kaladin is not merely reprimanded for disobedience: his body is attacked, his possessions are scattered, and the fragile means by which he sustains himself are emptied of their value.

Wider Significance

The episode exposes the division between the army’s official objectives and the lives required to achieve them. Sadeas defines bridgemen as a distraction whose deaths are acceptable so long as the regular soldiers and horses advance. Kaladin’s side carry contests that definition in practice. It demonstrates that the supposedly lowly crew can learn, coordinate, innovate, and survive when the structure is adapted to protect them. Yet because the broader assault was designed around their exposure, reducing their vulnerability destabilizes the very plan that exploits them.

The aftermath also shows why the tactic cannot be judged solely by its casualty count. Bridge Four survives untouched, but the army loses the timing necessary for its cavalry charge, and the officers respond by targeting Kaladin rather than reconsidering the system. The event thus turns a technical adjustment into an ethical confrontation. A bridge can shield the men carrying it, but it cannot by itself shield them from the command structure that has decided their deaths are useful.

The failure also becomes an important stage in Kaladin’s development as a leader. He accepts responsibility for the battle’s disruption even while understanding that his decision was made to prevent an otherwise foreseeable massacre. His authority comes from the front of the formation, from practiced movement, and from sharing danger; the army’s authority comes from rank, punishment, and the power to define which losses count. The side-carry disaster leaves that conflict unresolved, but it makes the contradiction visible: the survival of Bridge Four is both a tactical achievement and, within Sadeas’s war machine, an act that threatens the established order.
