than that from the west.
    Thirty-six hundred feet—twelve hundred yards—was well within the maximum range of the Model 10 rifle, but the Model 10’s effective range was only about eight hundred yards, although trained snipers with telescopic sights could score killing hits at twice that range. The twin-barreled, crank-driven Faraika I machine gun fired exactly the same round, and although its ballistics were a little better than the rifle’s due to its heavier, longer barrel, its accuracy in aimed fire was poorer, giving it approximately the same effective range. The heavier Faraika II, with its massive .54 caliber bullet, had slightly less maximum range than the Faraika I, but its effective range was actually greater: over fifteen hundred yards. That range would be reduced firing vertically because of gravity, but the Faraika II should still be able to reach thirty-three hundred feet.
    Fatigue parties armed with mattocks and shovels had hacked machine gun and rifle pits into Mount Karek’s recalcitrant soil on either side of the portal even before chan Serahlyk and Banchu’s bulldozers—assisted by liberal applications of dynamite—had gouged out proper approach roads. They couldn’t be provided with overhead cover if the weapons in them were going to have sufficient elevation to cover the portal’s airspace against the Arcanan dragons, but judging from the attack on Fort Salby, the heavy machine guns outranged the dragons’ weapons significantly. Nonetheless, chan Geraith had regarded rifles and machine guns as a purely interim stopgap until better arrangements could be made, which was precisely what chan Serahlyk was doing at the moment. His engineers were emplacing dozens of two-point-five inch Yerthak pedestal guns in permanent concrete-footed and protected positions placed to sweep the portal faces. The four-barreled Yerthaks had become at best obsolescent in their designed role as light anti-torpedo boat weapons for the Navy’s capital ships, but they had a maximum range of over six thousand yards and a vertical range of twenty-four hundred. They also had a peak firing rate of forty-five rounds per minute, and if their explosive six-pound shells were too light to stop warships, the Arcanans had discovered the hard way what they could do to dragons .
    If there’d been any doubt in their minds on that point, it had probably been resolved last week when a trio of dragons attempted to pass through from Karys. One of them had slammed to earth less than half a mile east of the portal, killing its pilot and nine of the twelve Arcanan infantry aboard when it crashed. A second, obviously badly wounded had made it back through the portal despite a savagely shredded wing. It had plunged through the opening in obvious distress and clearly out of control, yet somehow avoided plummeting to earth—undoubtedly thanks to yet another of the Arcanans’ unnatural magical spells—and staggered in to a clumsy, just-short-of-disaster landing. The third, made wise by its companions’ misfortune, had wheeled and fled before it ever crossed the portal threshold into the Yerthaks’ range.
    Ultimately, the pedestal guns would be augmented or even completely replaced by the heavier “Ternathian 37.” Formally the Cannon of 5037, from the year of its introduction, the 3.4 inch weapon was the most deadly field gun in the world, using cased ammunition and firing a nineteen-pound shell at a maximum rate of twenty rounds per minute. It had been in service less than twenty years, but the “37’s” reputation for reliability, toughness, and lethality had already attained legendary proportions. The Model 1, the lightweight version designed for high mobility with mounted units like the 3rd Dragoons, had an effective range of nine thousand yards; the Model 2, with a split trail to permit greater elevation and a slightly longer barrel, could reach eleven thousand. First Brigade’s artillery had been reinforced when it was dispatched
