Is it possible to defeat 1000 Archangels with just one Imp?

By the way, such a situation can actually occur. Let's say it's already the seventh week of an even match between the computer (with a handicap) and a human player. The armies are colossal. Let's say the human player was utterly defeated by a powerful hero and retreated. At the same time, on the seventh day, a hero with a large number of archangels attacks his castle (all troops have been hired, and there are no more left). Let's say there are 1000 of them. To defend himself somehow, the human player hires his powerful, but defeated hero with high stats and cool artifacts, and his army will consist of that very 1 demon, if it's, for example, an Inferno creature. So, it's a perfectly plausible in-game situation.
