In The Beginning:

“Heinrich Gimpel glanced at the report on his desk to make sure how many Reichsmarks the United States was being assessed for the Wehrmacht bases by New York, Chicago, and St Louis. As he thought, the numbers were up from those of 2009. Well, the Americans might grumble, but they’d cough up what they owed – and in hard currency, too; none of their own inflated dollars. If they didn’t, the panzer divisions might rollout of those bases and take what was owed the Germanic Empire this year. And if they collected some blood along with their pound of flesh, the USA might complain, but it was hardly in a position to fight back.”
