I see a few hits on the post so there's some people out there at least curious about Operation Juno. I'll pass on what I have learned about how SHIII GWX 1.~ treats the British evacuation of Norway so far.
On 6/5/1940, I was camped out at the entrance to Harstad and picked up a contact 190 degrees. It was a convoy of 5-6 Large Tankers, 2 Auxiliary Cruisers, 5-6 Troopships and about 4-5 destroyers. The destroyers were Hunt 1 and 2 class, and tribal classes. The screenshot below should clear up where I made my intercept.
Based on the internet link I posted before, I would say this is Group 1. I am also assuming they form up with Ark Royal and Glorious further out on 6/8/1940. The GWX team has been pretty accurate so far in regards to Weserabung (you do intercept Warspite if you know where to go), so I would assume they stick to the story of Juno pretty close.
The convoy travels at 10 knots, so I went to All Ahead Flank at 16-17 knots, got 90 aob to the Auxiliary Cruiser in front, went to periscope depth, rigged for silent running. I waited until the lead escort passed almost 45 degrees to port, put up the scope. The Aux cruiser was 30 degrees to starboard, 1000 meters away. At 20 degrees I loosed 2 torpedoes at him, one in fuel bunker, one under smoke stack. I also had a large tanker come into view at 350 meters. Loosed one in fuel bunker forward the engine room. The aux cruiser went down, the large tanker was smoking.
No pinging yet, but I'm also not leaving scope up either. No DDs coming at me. At this time, a Ju-88 makes a pass on a Large Merchant. Bomb hits amidships, makes fire and smoke, but does not sink him. The Junkers must be a lucky diversions for me becuase the escorts are filling the sky with lead. I see a Troop ship at 600 meters come into view. I launch my las forward torpedo. I aim just forward the 2nd mast where the fuel is. I over shoot and hit the tip of the bow. After I dive to 50 meters, the soundman reports I sank him! Wow, I new weak spot discovered for a troopship.
The convoy is 13,000 meters west of me, leaving the smoking ruin of the large tanker behind. I surface, run at full speed, man the desk guns. 4,000 meters out, lookouts report a Tribal 20 degrees to port at 8000 meters. He's either the rear guard for the convoy or hanging out as protection for the wounded tanker. At 3000 meters I pump deck gun rounds into tanker. 5 shots later the watch oficer reports that she's going down. At this point, the Tribal is 6000 meters away, closing straight at us at 36 knots. I crah dive to 165 meters. At 135, I cut engine from all ahead full to slow at 2 knots. Rig for silent running. The DD cuts his engine to medium speed at medium range, makes a few passes, drops charges, loops back, dos it again. But he's not following my track. He just makes passes over the same spot over and over again. I track all this on the hydrophones. 30 minutes later he quits to join the convoy. They are 20 kms out, but I'm not done yet. We'll see where this goes.
