Why HMS Warspite watched the Battle of Iquique

Why was HMS Warspite present to watch the Battle of Iquique?

She observed the fighting for lessons and reports while safeguarding British interests and people in the region.

The Royal Navy used Warspite to watch the fighting at Iquique rather than intervene in another state's war. Direct observation let officers assess how weapons and tactics performed under battle conditions and turn those observations into reports. Her presence also represented British interests in a region where trade and nationals might be affected by the conflict. The episode shows how a station cruiser could combine intelligence collection, lessons learned, diplomacy, and protection without becoming a belligerent.
