Hellsing: The Dawn Season 1

Young Walter and Alucard in his coffin are flown to Nazi-occupied Poland in 1944 to stop the Nazis' attempt to create a vampire army. Meanwhile, the Major arrives at the Nazi facility to see how the Doctor's work is progressing.

Young Walter on top of Alucard's coffin breaks into the Nazi facility and interrupts Major's dinner.

As Walter's fight with Major's supernatural driver, the Captain, escalates unfavorably, Alucard finally shows up, although in the shape of a small girl, and assists Walter. Also, Arthur Hellsing's loose behavior angers Hugh Islands.
