The Cross-Time Engineer by Leo Frankowski

So he refers the matter to the Holy Inquisition in Rome.

Conrad confesses his real identity to his priest, who can't decide whether this is an act of God or the Devil.

Conrad gives the order to advance to his three kolomels it's then passed on to their eighteen barons, their hundred commanders, their six hundred captains, their 3,600 platoons, their 21,000 knights, and their 126,000 soldiers (who of course only say, 'Yes sir!').

Used to show the size of Conrad Stargard's army when they march out against the Mongol invasion.

Given that an army of nomad warriors who had already conquered large parts of Asia and Eastern Europe would be used to taking casualties and have no shortage of combat-experienced soldiers adept at taking the initiative, this is rather implausible. This is used to explain the Idiot Ball later when the Mongols ride straight into the trap set by Stargard's forces. Decapitated Army: In The Flying Warlord, Conrad Stargard sends in a commando force who somehow identify and kill every commander in the Mongol forces in the middle of the night.Cool Horse: Conrad Starsgard finds that his mare Anna is as intelligent as a human, can outrun any normal horse, can kill if necessary and can even understand Polish! She's actually a genetically engineered gift from a time-traveling relative, trying to covertly aid Conrad after he was accidentally sent back to 13th Century Poland.Unfortunately this makes an enemy of the knight who had spent months setting up a trap for it. Beastly Bloodsports: In The Cross Time Engineer, one of Conrad Stargard's first controversial acts is to euthanize a bear that's being used for bear-baiting.However, Conrad himself does get shot in the face after removing his helmet, resulting in him losing sight in the eye on that side. The English longbows still readily put holes in the armor, but the Mongol horsebows largely just stick arrows in the armor's surface. Annoying Arrows: In the Conrad Stargard books, Conrad introduces the concept of plate armor to the Poles.

Alternative Number System: In the Conrad Stargard series, the new civilization Conrad starts up in Medieval Europe uses base 12 mathematics, because Conrad believes it's more useful than decimal.Adjective Animal Alehouse: The Pink Dragon topless bar in the Conrad Stargard series.Other works by Leo Frankowski contain examples of: Works by Leo Frankowski with their own trope pages include: Kren of the Mitchegai with Dave Grossman.
