to embark in a liner
on the Clyde on the same day. The stores for the three
Ports should arrive at Rosyth
and Clyde on 4th April. 3 cruisers of 1st
Cruiser Squadron and 1 of 18th C.S. should,
therefore, arrive at
Rosyth early on Thursday 4th

Battalions of the Narvik
Force should be ready to sail from the Clyde in a
liner about 7th April, accompanied by 2

be notified later but will

paragraph 13 and Diagrams
I, II, and III to Plan R.3
AIR COOPERATION –
7. Diagram II shows four cruisers as sailing
noon from Rosyth to arrive
Bergen and Stavanger
(presumably two cruisers to each place) before noon on the
following day. In
addition to A/S Air protection, long
protection will probably be required during daylight
hours. Dawn and dusk
searches of southern half of the North Sea may also be
required to give warning
of movements of enemy surface craft.
8. A/S protection will be required for both Trondhjem
and Narvik forces on
passage on West coast of Scotland and subsequently on
passage across the North
Sea. Long range fighter
protection from Shetlands may
also be necessary for the North Sea crossing for
the Trondhjem force.
There is no mention in Plan R.3 of an air
Stavanger force and presumable the subsequent movements
will adhere to the
outlined plan shown in paragraphs 11 to 27 of Plan R.3
9. Withdrawal of cruiser support from Northern
require reinforcement of air patrols between Faroes
and Iceland and between Faroes
and Shetlands. This
may require the withdrawal of Sunderlands
in 15 Group. Flying boats to operate
from both Shetlands and Invergordon.
SEAPLANE BASES ON WEST COAST OF NORWAY

and Bergen though it is probable that many other
anchorages exist in the
fiords. Military aerodromes exist at Vaernes
near Trondhjem and Bomoen
Bergen. The main civil aerodrome is 7 ½ miles southwest of
approximately sea level.
