Warspite transported to the Falklands War

How would Warspite react if transported to the Falklands at the Argentine invasion?

Assuming the battleship, withdrawing toward Ascension to join the task group is the proposed response; isolated action would be more dangerous.

The scenario is taken to mean the battleship Warspite, although the name could refer to a submarine and produce a different answer. Fighting alone would put the battleship in difficulty. Sailing north to Ascension and joining the task group would make her more useful. Her unfamiliar appearance could complicate identification and radar-based engagement. The proposed response is a deliberate withdrawal to cooperate with the fleet, possibly after attacking something nearby.
