Could X1 fight a German auxiliary cruiser on the surface?

How would HMS X1 have fared in a surface action against a German auxiliary cruiser?

Very badly; it would have to rely on torpedoes because its gun armament did not make it survivable in a surface duel.

X1 would be destroyed very quickly in a surface action against a German auxiliary cruiser. The submarine's conspicuous gun battery did not provide the protection, stability, or sustained fighting power of a surface combatant. In such an encounter, its torpedoes would become its meaningful weapons and preserve the basic submarine advantage of attacking from concealment. The comparison exposes the gap between cruiser-like armament and cruiser-like combat capability.
