Yes, it's possible considering the PoW. However he maneuvered Norfolk too to keep her very close to PoW protection.
Why, wanting just to protect Suffolk precious radar, he did not work round to starboard with Norfolk (a very expendable ship, without a good radar) to cover a possible Bismarck maneuver in this direction ? During the previous night, he had acted this way (keeping just a bit too far from enemy.....), but possibly the PoW big guns were too reassuring to leave their protection....

No, he just says, "
for reasons of tact" that W-W postponed the effectiveness of his shadowing (his only D U T Y as per his own choice since some hours......) to the "Security" of his ships. In time of war this has just one name....timid attitude (to be nice).

I did find it already, took from Ellis official report, only referenced in the autobiography. Please
read my transcript
before posting nonsense, in the urgency that you feel to "cover" the shame of this flag officer.
you wrote: "It is the responsibility of any naval officer to create a delegate who can take over in case he is incapacitated"
This just demonstrate that you apparently have never served in the Navy, did you ?
I have, and I know very well that the ultimate responsible on board is ALWAYS the commanding officer. When I was officer of the watch, I remember my commanding officer
always ordered to be called immediately in case of any emergency, and it was peacetime......
Wake-Walker could have delegated Phillips for the normal situations while sleeping, but
in case of emergency he SHOULD have asked to be awakened from his "incapacitating"

deep sleep. He possibly failed to instruct Phillips (or he requested NOT to be disturbed

) and apparently Phillips (if he was not asleep too

) failed to take any logical initiative (e.g. spreading the three ships to cover different directions) to re-locate Bismarck
for almost 2 hours......
I can't believe that a responsible officer (Phillips) could evaluate that it was not the case to awaken his Admiral while Bismarck was lost in Atlantic and all the 3 ships were stupidly moving in a single line behind Suffolk as in a naval parade.....
If you don't want to consider Phillips a total stupid, then it's ONLY Wake-Walker's responsibility if 2 precious hours were lost while Suffolk was desperately trying to locate Bismarck again, but in the wrong direction.
you wrote: " Since nowhere is there criticism of Wake-Walker's performance there can be no accusation of being asleep on duty."
There was not ONLY because Ellis "
for reasons of tact" did not accuse him, taking himself the responsibility of having lost Bismarck.....
I guess, however, that in case of a Court Martial asking "difficult" questions, all this "tact" would have been forgotten....
