Thank you for your enthusiasm.Byzantine Emperor Manuel I Komnenos contacts or tries to contact to Henry II about the war with a letter to Henry II. In the letter, Manuel I Komnenos says that he also sends ambassadors with the letter. But, we don't know if this letter even reached out to the Henry II. If the letter reached, there is a high chance of finding registered documents about it, and this can lead us to some new informations to pinpoint the exact location. Sadly, there are only few sources to gather information about this war, and none of them gives the exact place of the war. Due to the lack of ground survey about this matter, many cities claims that this war happened in their territory. If we can find the logs, we maybe can find the true location of this war.
