Hello everyone,
I tried to search a few sites and posts in here to find some kind of explanation of how combat using warhammer worked. Aside from some information like this: "The major advantage is the ability to transfer energy through armor, as well as to cause disabling dents", there isn't much about the combat itself.
I wanted to know a few technics using the warhammer as the main weapon of combat. There is any where that I can find? Or any information that you can provide me with?
Thank you so much for your attention and I am glad for any type of help you can provide me.
I am sorry for not being a profesional historian, rather just some nobody with a thing for medieval combat. But anyway:
What we often today call a warhammer can refer to a wide variety of weapons, and your failure to dig up techniques using it, I think, stems from the fact that most period (and modern) practicioners used different names. First of all, a hammer (in source material) is a, or several, spike(s). The tool now known as hammer is a maul or mallet. The weapon with a flat striking area is a poll. Note that weapons of this era, especially polearms, have widely varying names for things. You can find pollaxes consisting of a spiky end (hammer), hooky end (beak, pick or sickle like implement) and spearhed on the top. No axe or poll in sight.
If you are looking for techiniques for "flat surfaced striking weapons"/"hammers" look for pollaxe techniques. For "spiky bits"/hammers you can expand your search with bec-de-corbin, lucerne hammer or, you know, pollaxe. Either way, Talhoffer and HEMA (historical european martial arts) forums are good sources of departure.
This is a video showing what I understand is what you are looking for. https://www.youtube.com/watch?v=gTVC25hYJaY
I hope this was an informative post helping in your search for more knowledge, even if I am myself not at all an historian or authority on the subject.
Perhaps you might try the folks at /r/wma?
