In a war between Vampires and Werewolves, Vampires would win.

Well said opponent. First of all vampires could not even get into your fortified strongholds because they cannot go into a place uninvited so your moats are just a waste of time HA! All joking aside though the fact that vampres exist off of human blood does not necessarily put them at a disadvantage. Lets assume that the vampires knew that the werewolves were about to resist. They would obviously stockpile humans in their caves and fortresses in order to hopefully keep from starving during this devastating war. Also let me clarify that vampires do not die within hours or days without human blood they can survive for at least several weeks (I would say less than a month, maybe half) purely off of animal blood. Werewolves do not necessarily need blood to live but they do need meat, so why would they waste all of their time killing off all the humans. There are four big reasons why they would not. First, humans are as good of a food source for them as for the vampires, killing them off would be a waste of sustenance (unless they eat them all after killing them but that many humans at one time would make them bloated and slow) and while they are exterminating humans the vampires could be exterminating all animal life but then the war would just be a silly waste of time and both species would die of starvation before the war was even concluded and then the earth would be devoid of all life. Secondly, depending on the time period that they are busy exterminating human life (I would assume they would do it during the day also) this could be a major distraction from the war. Thirdly, while humans are weak, petty creatures compared to these two races, beginning a holocaust on humanity would only draw them into the war. Humans are vulnerable when they believe vampires and werewolves are just fairy tales but what if they suddenly decided to take up arms against them. Fourth, humans are excellent recruits for both sides. Both vampires and werewolves merely need to bite humans to turn them. Killing all of them would merely keep your side from replenishing their numbers. The final point I will make on the food and sustenance issue is that while vampires merely need to drink blood werewolves need to eat flesh. If vampires rationed blood out appropriately they could make their stockpiled humans last forever because blood replenishes. When you bite the leg off of a person it isn't going to grow back so, as I have made very clear in this segment, I believe werewolves eating habits to put THEM at more of a disadvantage than VAMPIRES eating habits. Now I hate to break it to you sinister but werewolves do not have the mental capacities of vampires. Yes they can take human form just as easily as vampires can but one thing is fact, when werewolves are in wolf monster form they at the very least have less mental capacity than in their human form. Some sources would portray them as mere mindless monsters when in wolf form but still others merely say that have less mental process and more hunger for flesh and death (which is not necessarily a weakness but at the same time could be used against them). If I have read correctly, while werewolves are great in power they are still technically human and therefore mortal. Vampires on the otherhand are immortal, while there is a middle stage where they are half human and half vampire, once they turn full vampire there is only a human appearance and no matter what form they are in they are vampire and nothing else. Except for recent additions to their numbers vampires are old and wise. This could be a major advantage especially if the vampires were to have a council of elders to guide them on what to do during this epic war. On another note, alot of werewolf tales say that they only turn into wolf monster form during a full moon. That means the battles would merely occur once a month. During the rest of the month the vampires, who are only limited by daylight not by a certain type of moon, could spend their time figuring out who of the humans is actually a werewolf and pick them off one by one without a hitch and they could spend that time greatly increasing their numbers in preparation for the next battle. Now that wouldn't be a very exciting war now would it. I will conclude by saying that while my side is weak to such thing as crucifixes and such, werewolves are weak to silver. I do not know if vampires would use firearms necessarily, I think I have heard in some variations that vampires do not believe in using them, but the werewolves, whom I have never heard of using weapons and who typically engage in close combat, would be in trouble if vampires armed themselves with swords and other handheld weapons crafted from silver. Even if they did happen to start using atoprophic objects as weapons that would not put them at an advantage if vampires took advantage of the werewolves main weakness by utilizing silver weapons. Before I bring up the ever present topic of vampires sleep cycles I would like my opponent to address in his next argument how much sleep werewolves need exactly. I would assume that they need to sleep eventually but I do not know of any film or literature that addresses that so before I attack that subject I would like my opponent to educate me on werewolf sleeping cycles.
