This desertion, however, was the direct cause of Aquilonia's defeat by the desperate Nemedians, and brought down on the Bossonians the cruel wrath of the imperialists--intolerant and short-sighted as imperialists invariably are. Aquilonian regiments were secretly brought to the borders of the marches, the Bossonian chiefs were invited to attend a great conclave, and, in the guise of an expedition against the Picts, bands of savage Shemitish soldiers were quartered among the unsuspecting villagers. The unarmed chiefs were massacred, the Shemites turned on their stunned hosts with torch and sword, and the armored imperial hosts were hurled ruthlessly on the unsuspecting people. From north to south the marches were ravaged and the Aquilonian armies marched back from the borders, leaving a ruined and devastated land behind them. And then the Pictish invasion burst in full power along those borders. It was no mere raid, but the concerted rush of a whole nation, led by chiefs who had served in Aquilonian armies, and planned and directed by Gorm--an old man now, but with the fire of his fierce ambition undimmed. This time there were no strong walled villages in their path, manned by sturdy archers, to hold back the rush until the imperial troops could be brought up. The remnants of the Bossonians were swept out of existence, and the blood-mad barbarians swarmed into Aquilonia, looting and burning, before the legions, warring again with the Nemedians, could be marched into the west. Zingara seized this opportunity to throw off the yoke, which example was followed by Corinthia and the Shemites. Whole regiments of mercenaries and vassals mutinied and marched back to their own countries, looting and burning as they went. The Picts surged irresistibly eastward, and host after host was trampled beneath their feet. Without their Bossonian archers the Aquilonians found themselves unable to cope with the terrible arrow-fire of the barbarians. From all parts of the empire legions were recalled to resist the onrush, while from the wilderness horde after horde swarmed forth, in apparently inexhaustible supply. And in the midst of this chaos, the Cimmerians swept down from their hills, completing the ruin. They looted cities, devastated the country, and retired into the hills with their plunder, but the Picts occupied the land they had over-run. And the Aquilonian empire went down in fire and blood.
