V.V. (12) assonance, alliteration

[jbor]

     ... General Lothar von Trotha, having demonstrated to Berlin
    during his Chinese and East African campaigns a certain expertise
    at suppressing pigmented populations, was brought in to deal with
    the Herero. ... (245.3)

The alliteration and assonance in this sentence seem to me to preempt the
facetious/sarcastic tone of the narratorial aside which ends the paragraph.

Q. Which of the ostensible narrators (Pynchon, Mondaugen, Stencil) is
responsible for the substance and tone of the historical summary here, and
the comparison with the Shoah which rounds out the paragraph?

The segue from Kurt's dream to the execution of the Bondel is effected by
the appearance of Vera Meroving. (244-5)

Q. What is the significance of Vera's sudden appearance in Kurt's dream, and
then her reappearance in the "real time" of the narrative? (Indeed, apart
from the prepositional phrase "At dawn ... " at 244.4 up, what indication is
there that there has in fact been a move from Kurt's dream back into
"reality"?) Does Vera's apparent savouring of the Bondel's execution as a
spectacle relate back to the way Victoria Wren "turned away to gaze, placid,
at the rioting" in Florence (209.3)?
