'A ship doing between 15 and 22 nautical miles an hour is in their opinion an almost imporrible victime for a U-boat.
And such ships can be built easily in their opinion.
Instead, our Victoryh [Liberty] ships do little better than ten miles and English ships are built to do only eight and nine.'
In fact, those 2,700 Liberty ships maxed at around 13 mph (11.5 knots) on their 2,500 HP engines.
But the US was also building 500 Victory ships, whose 8,500 HP engines drove them to nearly 20 mph (17 knots).
But the first of the faster Victory ships was not delivered until 1944, by which time the U-boat Battle of the Atlantic had been pretty much won by the Allies.
So the need for speed was not so great there.
Still, the Pacific was different, in that longer distances made faster speeds a logistical advantage.

Here's another Baldwin quote:
Indeed, Admiral Doenitz's alleged exhortations to his sailors to "Kill! Kill! Kill!" are reminiscent of the ruthless "spurlos versenkt" policy of the first World war."
They are also reminiscent of Adm. Halsey's exhortations to his sailors to "Kill Japs! Kill Japs! Kill more Japs!"
