BDU Ark Royal messages - does it exist?

[claretabroad]

I'm at sea in february 1940 and I get several BDU messages telling me the Ark Royal is heading to Portsmouth.

Would this be eye candy or an actual scripted event?

Messages are as follows:

1) Proceed to channel approach between start point and Quessant

2) take up attacking position along the line of lizard head - los sept isles. Ark Royal is expected to pass eastward early on 13/2. Renown and Exeter early on 14/2

3) Message 2) repeated

4) Ark Royal was in 45 degrees north, 15 degrees West @ 1900/12/2 speed 22 knots expected port of destination is Portsmouth

5) U-37 and U-48 (I'm U-30) make every effort to take up attacking positions ordered. Until boats are dismissed from this position only particularly valuable targets are to be attacked. U-26 to occupy sqaure 3000 BE right half and square 1000 BE left half as attack area

6) U-26 to operate North of 40 degrees 30 minutes North. U-48 South of the line.

Any advice would be greatly appreciated.
