When me and my friend were playing as the Turks, we wanted to recapture Silesia from the French (an absolutely enormous country), so we build a Jihad in Rum and filled it with 2000 soldiers, before heading off into Trebizond to get to Silesia (it was the only way there).

However, this was both of our first Jihad (I have used crusades, but he has done neither) and we had no idea that Orthodox nations don't allow Jihads to pass through (Trebizond and Constantinople were held by the Byzantines) and so when we tried to march, it asked if we wanted to declare war. Well, being already in a constant war with France, and having the threat of a huge Almohad force in the Middle East, we decided not to, so our Jihad slowly lost numbers as it stayed in Rum.

Bugger.
