THANK YOU for finally answering my question.
From: Koop/Schmolke, Die Panzerschiffe der Deutschland Klasse; 1993; p230.
The 10.5cm guns (4.1”) were hardly used, only 80 rounds used without any hits
A question I'd like the experts on this board to answer; during the River Plate battle, I know that GRAF SPEE's main battery did virtually all of the damage, with the secondary 5.9" guns not doing that well. My question...did the British cruisers ever approach close enough for the 4.1" guns to engage them and if so, did those guns score any hits or were they silent throughout the battle?
