Rise of the Horde

Aldrath’s consolidation plan changed the terrain of the campaign in the way that major decisions changed terrain, not by removing the difficulties but by replacing them with different ones whose character the existing defensive responses could address.

The supply depot consolidation eliminated the dispersed convoys. The relay stations’ replacement by direct messenger communication made the Throat Teams’ interception operations more difficult because single riders on varied routes were harder to predict than network traffic on fixed relay paths.

The consolidated camp’s tighter geographic footprint reduced the isolated elements that the Hammer Teams had been finding outside the main body’s protective umbrella.

In exchange, the consolidation produced a force whose supply chain now ran in daylight on heavily escorted routes whose predictability was enforced by the reduced number of available paths.

A camp of twenty-three thousand soldiers consolidated from dispersed positions into a single tighter footprint required a perimeter that the standard Threian camp design had not been built for, and the extended perimeter required more sentries to maintain adequate coverage, and more sentries meant more of the main body committed to standing watches rather than to the offensive operations that the campaign’s resolution required.

Khao’khen received the Verakh assessment of the consolidation on the third day after it was implemented and sat with it.

"They have solved the immediate problem," he said.

"At cost," Sakh’arran said.

"At cost that is sustainable in the short term. The supply chain runs slower and on fewer routes, but it runs. The communication network is less efficient but functional. The main body protection of the consolidated perimeter reduces offensive mass but maintains cohesion." He looked at the map. "It is a good solution to the problem we were creating. We do not fight a good solution. We create a new problem."

"What problem?"

"The problem that consolidation creates for the ground itself. The provincial roads that supply the consolidated position are now the only supply routes. They have been built for civilian traffic, maintained by the provincial road authority, carrying the weight distribution of grain wagons and merchant convoys. A consolidated military force of twenty-three thousand soldiers receiving supply by heavy-escort convoy on two predictable routes is applying sustained heavy traffic to road surfaces not designed for it." He pointed to the specific sections of the approach routes where the road’s grade and construction made it most vulnerable.

"We do not attack the convoys. We attack the road’s ability to carry them."

"Road interdiction."

"Road displacement. We use the troll specialists. At night, in the sections where the road surface is oldest and the substrate beneath it is softest. We remove the paving stones from their bedding and stack them beside the road in organized fashion. The removal requires repair before heavy convoy traffic can use the surface. The repair requires the provincial maintenance equipment that the combined force is not carrying. The repair must be improvised from available materials, which is slower than standard repair, which means the convoy arrives later than planned, which means the consolidated depot runs at lower stockage than the operational plan requires."

Sakh’arran ran the calculation. "Persistent displacement across multiple sections simultaneously could extend convoy transit time by half a day per run within a week. A full day within two weeks."

"At current supply consumption rates, a consistent half-day delay compounds. The depot stockage does not crash. It shrinks gradually, and gradual shrinkage is the supply equivalent of what the Throat Teams were doing to the nervous system: a persistent wrongness that cannot be addressed by a single corrective action."

The road displacement teams went out for three consecutive nights, working sections of the two approach routes in the pattern that maximized the repair burden and minimized the risk of encountering the combined force’s cavalry patrols, whose routes the Verakh network had mapped with sufficient precision to allow the troll specialists to work in the windows between patrols.

The troll specialists were not just warriors in the conventional formation sense. They were the engineering and construction corps whose value the campaign had demonstrated in multiple contexts, from the catapult assembly at Greywater to the tunnel preparation at Thornfield.

What they brought to road displacement was the combination of raw physical capability and methodical work habit that produced consistent results even in the darkness and the time pressure that the operation required.

On the first night, three road sections. On the second, five. On the third, four, with two sections repaired from the previous nights’ work displaced again. 𝕗𝚛𝚎𝚎𝐰𝗲𝗯𝗻𝚘𝚟𝚎𝗹.𝕔𝐨𝕞

The combined force’s supply convoys began arriving at the consolidated depot a quarter-day late by the fourth day. Half a day late by the seventh.

Aldrath dispatched engineer teams to repair the roads. The engineer teams required cavalry escort because unescorted construction crews were precisely the kind of isolated element that the Hammer Teams had been operating against. The cavalry escort came from the main body.

The roads were repaired. The troll specialists went out the following night and displaced them again.

Snowe brought the logistics summary to Aldrath on the eighth day of the consolidation phase and placed the numbers on the map table. Effective fighting soldiers in the main body: nineteen thousand two hundred. Supply depot stockage: sixty-four percent of planned. Mage replacement equipment integration: three of six practitioners at full readiness, three still adjusting to unfamiliar equipment.

"We are being worn," Aldrath said. "Not beaten. Worn. Every action we take to address the wear creates a new exposure that the wear finds and exploits."

"Yes," Snowe said. "That is the pattern."

"He is driving us toward a threshold. A point where the accumulated wear has reduced our effective mass to the ratio where his force size begins to overcome our numbers on the kind of ground he chooses."

"He has been driving toward that threshold since the depression engagement. The question is how far he is from it."

Aldrath looked at the numbers. "Close enough that waiting for the threshold is worse than forcing the engagement before we reach it."

"The valley," Snowe said.

"The valley," Aldrath confirmed. "Everything. One axis. Through the northern mouth. The valley’s geometry costs us at the road. We pay that cost now at the level we can manage rather than paying a worse cost at the threshold level he is preparing for."

It was the logic of a general who had run out of safe options and was selecting the least unsafe one remaining. Snowe understood the logic. He had been watching it develop for weeks.

"When?" he asked.

"Night," Aldrath said. "He expects the daylight approach because every previous Threian assault on the valley has been daylight. We move at night, before his surveillance can fully assess the formation, at the pace that keeps us in the valley’s narrowest section for the minimum possible time."

"He will know we are moving."

"He will know. He will not know we are inside the valley until we are inside it."

"That is a very narrow window."

"Yes," Aldrath said. "It is the window we have."
