They heard Albrecht typing on a computer keyboard. “Give me a moment to get a better perspective on this computer map. There. No, I think you’re right. The old Chinese sources say that five hundred men worked two years to build the fort. They were in the middle of the Sino-Xiongnu War. Xiongnu was the Chinese name for the Huns. Zhizhi, leader of the Huns, was expecting a Han army of up to three hundred thousand men to arrive at some point, so the fort would have had to be strong. It would be built in the heights, and it would need a water supply. We know it was high-walled because when the Chinese did come, the only way they could storm it was by piling dirt up beside it until it was even with the wall. The fight was furious, and even Zhizhi’s wives shot arrows from the battlements. The Chinese overwhelmed them and won. I don’t think the fort was at the modern marketplace. The ruins under the market are more likely to be either a habitation or a cemetery.”

“What will Mundzuk’s grave consist of?” asked Remi. “What do we look for?”

“I’m sending you pictures of the known burials of the earliest Huns in Mongolia. They were buried under mounds. There’s a burial chamber made of stone, and then over it are layers of stone, soil, and logs of Siberian larch.”

“That’s close to the sort of thing we found in France. It had been made of logs plastered with mortar.”

“Look for any natural feature that could have been a mound. Most likely, it was leveled intentionally or by time, the wind, and the river. But Mundzuk would never have been in the fort, which was destroyed three hundred years earlier with Zhizhi’s defeat. It was a ruin long before Mundzuk’s time. Remember, we’re looking for a king who died just during the migration to Europe. If the market is over a burial complex, Mundzuk’s grave would be one of the last.”

Remi said, “Is there any way to know how his father’s death affected Attila?”
