SUBJECT:    Scandinavian Operations - Resume of (Continued)
---------------------------------------------------------------------------.
 
   (e)  The RENOWN engaged the SCHANHORST off Narvik. Reported
that SCHARNHORST was hit, but escaped in mist and smoke screen laid
by the cruiser HIPPER.
 
    5. On 10 April,  an air attack was made on Scapa Flow; 50-60
planes participated. There were several capital ships, cruisers, and
other light forces at the base at the time. There was no damage to the
ships and no casualties aboard. Some damage ashore and some civilian
casualties. No fewer than 6 German planes were brought down.
 
  6. April. 12, the British were reported to have undertaken 
landing operations with preparatory attacks from the sea end by air at
various points on the west coast. Attacks on Narvik, Trondheim, Ber-
gen and Stavanger have been reported.
 
             On 16 Apri1, the British occupied the Faroe Islands.
 
             On 18 April, the British made a determined air and naval 
attack on Stavanger to-destroy the important air field located there.
 
  7.  An analysis of the various reports of operations in Norway
leads to the conclusion that Narvik, Trondheim, Bergen, Stayanger, and
Kristlansand remain in German hands, but that British and perhaps some
French units have effected landings in force at Andelsnes,  about 100
miles south of Trondheim, and at Nansos, about 100 miles north of Trond-
heim. From these two points columns are converging toward the area to
the eastward of Trondheim.
 
  8.  The main effort 0f the Germans is being made to the north-. 
eastward of Oslo,  in which area they are estimated to have 30,000 to
40,000 troops. The German advance from Oslo has been impeded by the
Norwegian Army, which is reported now to be well organized, with com-
petent staff work, in this area. The Norwegians plan delayed action
tactics with retirement toward the coast instead of toward Sweden. The
reports of land engagements in the Oslo area have been too contradictory 
and confusing for satisfactory analysis, although it is evident that Nor
wegian operations have appreciably slowed the German advance. The most
recent reports indicate two major engagements - one north of Trondheim; 
the other, north of Oslo.
 
   9.  The British minefields planted in the Baltic and in the 
Skaggerack are apparently not sufficiently dense to interfere seriously
with the movement of German vessels. The minefields in the Skaggerack
can not be defended against German sweeping operations. According to
