The idea was to use Nazi attack on London as an excuse and a diversion in order to invade and wipe out heretics. Since Maxwell was Catholic while England is mostly Protestant, to Maxwell everyone in London except for his men was a heretic that had to be destroyed, Nazis, Hellsing and civilian Londoners included.
Major only had around 1000 soldiers, Maxwell had 3172 knights trained and armed to fight monsters (and that is without Anderson's Iscariots), so he thought it was enough. Also originally Catholics thought Alucard was out of the picture stuck in the middle of the ocean, yet when it became clear Alucard was coming back, Maxwell decided to continue with his plan regardless, since he became super arrogant with his new title at this point.
Man_Internet said:2. Alucard is the first vampire right? How did he become one? All I could find in the wiki is that seconds before he was executed he licked some blood off the floor. How \ why that would turn someone into the first vampire in history is unclear to me.
It was never stated he was the first vampire, we actually have no idea about that, also since he's only around 600 years old, there must have been other vampires throughout history. What is known is that his vampirism didn't come from another vampire, but was self-obtained, which is a rare origin for a vampire, yet not completely unique either, which we also know for a fact.
Basically by Hellsing lore on large battlefields where lots of people were slaughtered, sometimes consciousness/souls of those countless killed unwilling to parish try to cling to this world by entering a body of their last standing dying/soon to be killed comrade. This kind of life transfer occurs through blood that gathers and flows to the chosen person, that person can accept the offer by drinking said blood in order to become a vampire carrying consciousness/souls of the blood overpast owners or refuse the deal altogether. Alucard did accept the deal, after his army was defeated and destroyed by Ottomans he licked the blood of his executed soldiers right before he was himself beheaded by an Ottoman slaughterman. On the other hand, after getting shot by a Soviet shooting squad in Berlin, Major also had a chance to become a vampire the very same way as Alucard did, yet Major refused the offer since he despised vampirism due to its hive mind properties.
Man_Internet said:3. Why did Walt turning into a vampire cause him to get younger? For every other vampire it made them stop ageing but not become progressively younger.
Major's army was made from old men WW2 Nazi veterans. They all did become younger after Doc turned them into artificial vampires. Walter's age became unstable because his turning had to be done in a hurry, plus Doc made an artificial vampire on steroids out of him, much more powerful from regular Major's soldiers, so there was a price to pay for such experimental treatment.
Man_Internet said:4. What's up with Walter's "powers"? They are far beyond what a human can do with regular wires. Is there magic involved? Any explanation beyond "he's very skilled"?
No detailed explanation here, sorry.
Man_Internet said:5. In the wiki it's said The Doctor is immortal, which explains why he hasn't aged between the first time we see him in the 40's in The Dawn and during Hellsing. However it doesn't look like he's turned into a vampire so how did he achieve immortality?
No detailed explanation as well. Also Doc was a genius biologist, so I guess he just figured something out. He would not age, yet he also seemingly had no special battle abilities whatsoever, so whatever he did to stay young had no military use to Millennium anyway. Or maybe he was an artificial vampire after all, yet simply didn't care to learn any fighting skills.
Man_Internet said:6. Alucard is "dead" at the start of the show which is around the 1980's and is revived by Integra's blood. This means someone \ something managed to "kill" him between 1945 and the 1980's. This incident is never mentioned in the show, as far as I noticed. How did this happen?
He's not dead at this time period, more like hibernated. While Integra treats Alucard as a person, it appears that Arthur Hellsing thought of him more as of a living weapon. During WW2 Alucard was deployed to the battlefield, did his job, got back and was put on a shelf on stand-by mode until he was needed once more.
Man_Internet said:7. Anderson is shown to have incredible regeneration powers in episode 3 when he basically comes back to life after being shot in the head, however in the final battle his arm is injured and does not regenerate at all. Why? seems very inconsistent.
A couple of bullets from Alucard's Casull pistol is nothing compared to Alucard's Jackal. Remember, Walter made Jackal specifically as an ace weapon against Anderson. It just inflicted damage faster and in more volume than Anderson was able to regenerate on the fly.
Man_Internet said:8. How does magic work in the show's universe? This isn't really a plot hole, I'm just curious because the logic and mechanics of magic are never properly explained.
Some magic was explained while some wasn't, you'll have to be more specific with that question.
