So,

how do I load my cannonfodder into Ferries? I've already tried right clicking but it doesn't work. I want to see my army getting crushed as soon as possible so...HELP!

It should be as simple as moving them there. Make sure you've built a transport ship and not a warship. Also make sure that the ship is able to get close enough for them to board it.

hmmm already tried that, no luck.

So, describe in a bit more detail. What's the map, what is the name of the type of ship you're trying to board. Are you boarding it on a beach, or on a cliff? I can't remember if the beach / cliff thing matters. I think in the options when you select a ship, there's one of them to then select people to board it. Have you tried that route, i.e. select the ship, then click the "load" icon, and select people (It's been a while since I played this, so I may be confusing it with other games)?

well it looked cliff-like... it is an island map. and all of the island are kind of surrounded by cliffs. maybe thats the reason?
Because whenever i chose a group of cannonfodder and want them to board a ferry, they just run around for a while then stop.

If you let me know the map, I'll have a look, but that may take some time depending on how far you are through the game.

As a said, it should be simple, so the cliff thing sounds likely.

the problem is, i forgot which map it was...the game crashed so i couldn'T save

Ok, well if you find it again, let me know. I'm afraid that as it stands there's not much I can do. I can tell you that the ferries work, normally...

The name is Islands of death i think. still doesn'T work right clicking on them.

Warlords Battlecry 3 DOES NOT SUPPORT working ferries. Only WBC1 does.
