"Well we have to work with what we got Gil, nothing else for it."
"(Sigh) I don't know, I tried already, and none of them have any kind of fighter instinct."
"You probably were treating them like something you scraped off your scales."
"Oh and I suppose you'd treat them better?"
"Not really, but they might respond better to me, I can be diplomatic."
"Ha ha ha ha! YOU!? Diplomatic?! Alright I'll help because I gotta see this!"

You and Gil go to back to Moreau's freak town, where the freaks stare at you again. You call everyone to gather around.

"Alright you freaks come gather around! Now then, it has become quite apparent to me that all of you are a bunch of hippy weaklings who would've been killed a long time ago, if you actually lived in reality. Well soon the reality will come to rectify that mistake if you don't stand up to the Martians that will be coming to annihilate this little so called paradise you all have."
"Oh maybe if we're real nice to them, they'll let us live!" one says.
"Not familiar with Martians are you? They're not the nicest beings in any sense of the word. They've attempted to conquer this planet several times and have killed millions of humans. What do you think they'll do to you freaks?"
"I'm sure they can be reasonable, if we just ask them nicely to live with us in peace."
"Argh! Didn't you fucking freaks hear what I said?! I said they'll fucking kill ALL of you! Now if you fight back you might have a chance! All you have to do is evacuate your town and whatever little settlements you have on this island and take to the wilderness. You could easily conduct a successful guerilla war on here. Martians aren't very good tacticians and have bad immune systems. They'll probably catch malaria and every other disease under the sun attempting to root you guys out and I of course will be the one leading you to victory!"

Your speech is met with more silence and disapproval.

"No! We shall not give in to hatred and violence! Those are the old ways!"
"Yes and some of us never followed those ways in the first place!"

"That went over real well, got any other ideas?" Gil asks you.

You continue to speak

You're determined to make these freaks fight, mainly because you're too stubborn to give up. You start going on about natural law, survival of the fittest an all those other might makes right philosophies you subscribe to. After about a day of this, some of the carnivorous and omnivore freaks begin to find something that still dwells within them. Even the herbivores start tapping into their human side to get that aggressive streak within them.

Now you've got something to work with! Unfortunately you don't have much time. You and Gil only manage to give the bare minimum of training when the Martians arrive. You manage to get most of them to evacuate before they do their initial saucer bombardment. Dr. Moreau stays behind to die after seeing what you're turning his "citizens" into; he doesn't want to be any part of it. As far as he's concerned his Utopia is over.

But your battle is just beginning! Just like you suggested you, Gil and the freaks take to the jungles which they all know like the back of their paws, hoofs, etc. You get some of the freaks that have burrowing skills to create a system of underground tunnels, where you do your training, planning and where you strike from.

The Martians meanwhile use their superior technology to combat you, but they aren't very successful. They can't just destroy the entire island since they're attempting to hold it, this all results in a war of attrition that ultimately ends very badly for them as they die of diseases, ambushes and the like. It also doesn't help when you get a hold of some of their weapons. Eventually they pull out. Gil parts ways with you at this point and goes back to live in his bit of swamp where he originally wanted to spend the remainder of his days. Nobody ever bothers him again. You however take control of the island. The freaks are a lot more to your liking now. No more of that pussy peace shit. No more "No spill blood law" either. The only law now is the law of the jungle. (Well since you're in charge, you tend to make "rules" that benefit you though)

You live out the rest of your years in relative luxury mating with a Fox woman on a regular basis. Amazingly she gives birth to some weird crossbreed. You "imaginatively" call him Wox and teach him the same thing you taught everyone else. When Wox grows up he's so grateful for your ruthless teachings that he decides that you've earned you rest and kills you for ruler ship of the island.

You don't blame him though it's the natural order of things.
