@micnorton9487 He said "Shipping" you twit. That means Merchant Ships. Yes - the Japanese sent their submarines after WARSHIPS - not Merchant Ships. That was their mistake. Yes - they got a few Warships - but - they made no impact on logistics which is what submarines are good at. Look at what the Germans were trying to do in the Battle of the Atlantic. The Germans knew how to use their Submarines - the Japanese didn't. .
