Guelf stood, his balls crawling up inside as he saw what remained of the enemy rank; smoke and flame billowed up behind them. Even if the asphalt of the surface didn’t catch, it would be a while before anyone could cross that bridge.

It only takes one dart thrower . . . he thought.

“Back, retreat!” he shouted, and the oliphants echoed it. He stooped and snatched up an intact shield someone had dropped. “Back! This place is rigged to burn. Fast, fast!”

The men turned and trotted away; some of them had the arms of wounded comrades over their shoulders, and others were making rough carrying seats from two pairs of crossed hands. One giant even had an armored form slung across his back. The knights and squires were last, backing in a controlled rush and trusting to their fuller armor to shield their subordinates.

Chenoweth’s eyes flicked back and forth over the broken bodies they left behind. Guelf was doing the same. Stopping to pick up the dead was out of the question; even the wounded weren’t always possible. If they could recognize the fallen, it made it easier later to compile the lists of the dead.

Then they were out, running, running for their lives to the rail bridge, 84 to the left and Westbridge dead ahead, engulfed in flames. The warehouses behind them burst open like an overripe watermelon dropped off a castle’s battlements, the stacked incendiaries collapsing as the thermite charges ruptured their glass walls. A wave of liquid fire poured out of the ruined buildings, running knee-high like surf on a beach.

The screams of the enemy rose to a peak and then died as the fire ripped the air out of the narrow alley. Men fled burning; even Boise’s discipline couldn’t take this.

Guelf leapt aboard the first of his contingent’s pedal cars, ignoring the Odell brothers doing likewise ahead of him.

“Push, damn you!” Guelf screamed. “Half push, half pedal!”

His men threw their weapons and shields on the cars; some clambered aboard and threw themselves into the recliner seats, booted feet searching for the pedals. The rest rammed their shoulders into the sides, so enthusiastically that Guelf had to grab for a support as his car almost came off the tracks. It began to rock forward with the rough, irregular neglected bed giving it a sickening side-to-side motion as it gathered speed. He and a few others went around the edge, bending and straining to get the now-trotting groundlings up and onto the surface.

“Pull your arms and legs in, don’t get in the way of the men pedaling!”

“Too close!”

More stacks of incendiary shot and barrels of the noxious stuff were going up in the warehouses to either side. The wave of heat washed over them. Men covered their faces and held their breaths and pedaled even while they coughed and retched. The heat seared the membranes of their noses and throats, and hoarse screams sounded. Fortunately the only way to panic was to pedal harder.
