1210 - Incoming Radio Reports:

From O.K.W.:
a) Despite the Möhne reservoir dam and the Edersee reservoir dam still damaged from the 17 May 1943 British raid, total water output was restored to full capacity by today, achieved by the implementation of the emergency pumping scheme inaugurated the previous year.

From B.d.U.:
a) If numerically possible, U 180 (IXD1; Fregkpt. Werner Musenberg) is to be escorted by Ju 88 from 8° W, as of 26 June. Destroyer escort is also anticipated. The boat is carrying Japanese Officers, also, valuable apparatus and gold.

To U 115: As there is still no reports from supply group U 488 (Oblt.d.R. Erwin Bartke) and "Schliemann", all southward bound boats are duty bound to proceed at economical cruising speed in order to have more freedom of movement in the event of enemy contact. RST: Switch to Circuit Afrika-II, on 28 June, 1400h. - BdU -

a) British Chiefs of Staff circulated the "German Long-Range Rocket: Evidence Received from All Sources" report, with details of our V-Weapons potentially capable of carrying 2 to 8 tons of high explosives.
