The IJN had a major role in the Pacific in several ways, including the siezure of several German island bases, and above all the siege of Tsingtao, the largest German base in the Pacific, their Pacific Gibralter which they had lavisxhed vast amounts of money and effort. THis was both a naval and a land engagment and lasted a long long time and involved thousands of troops on both sides and ships and many remarkable feats by both sides. Unfortunately the isolation of the base doomed the German efforts hence the dispatch of Graf Spee to try to get home. He almsot made it, if he had only engaged the British ships as they lay at anchor in Stanley Harbour trying to get steam up. The outcome might have been very differnt, tho acts of valour continued after that, it was a doomed result for the two surviving ships.
This would be an ideal battle scenario for the mod.
