INTRODUCTION
Most Evony Skill Books work as expected, the exception is the Battlefield Speed & Range Skill Books.
A common area of confusion is the difference between March Speed and Troop Speed. The March Speed Increase Skill Book is for getting to the Battle (which is graphically visible in-game) faster. The Ground and Mounted (Movement) Speed Increase Skill Books should work during the Battle (which is NOT graphically visible in-game) to increase movement speed per turn. However, it appears that Evony currently has those two (2) Skill Books turned off.
The following is speculation, but it appears that the Evony game designers were going to make changes to increase the overall Battlefield length around the same time the Siege Ranges were changed, but for some reason the Battlefield length changes didn't work (probably because it tipped the troop balance in one direction or another too much). So, as a temporary solution, the battlefield length changes were dropped and the Speed Skill Books were turned off, but the Siege Range changes were partially left in place (as they are currently). I'm sure at the time, they were thinking that they'd get back to it and fix it, but it's been this way for around 3 years, and doesn't seem to be high on the priority list to fix.

Use the best six (6) choices from the list of fourteen (14) above for your individual Defense Strategy (best choices will vary from Keep to Keep).
Mounted (Movement) Speed Increase and Ground (Movement) Speed Increase do NOT work so don't waste a Skill Book slot on either of those.

Use the top six (6) choices that will work on the selected pair. The bold choices (1-4) are important to have functioning on the pair (if possible). In most battles, the non-bold choices (5-13) probably don't make much of a difference.
For the Ground (Movement) Speed Skill Book, just because it's probably turned off right now, doesn't mean you shouldn't be using it. It may make a difference in more complex battles, or it may make a difference in a way that's never been tested. There's just never been a test done to prove that it makes any difference. Also, Evony could decide to turn it back on and not tell anyone. Unless you have premium Debuff Skill Books to replace it with, choices 6-13 are probably not going to make any difference either.

The HP & Defense Increase Skill Books will help reduce the number of wounded, but they will NOT help get the number of wounded to zero. Only increasing the total attack damage will do that.
Note: The Mounted (Movement) Speed Increase Skill Book does NOT work for PvM. This has been tested and proven with published data.
