I've been going throught the KTB and standing orders, and this is what I have come up with so far. I've only gotten up to the fall of 1941. My own shorthand about missing things are included, and if anyone can fill me in on some of the details, feel free.
Code:
Prize rules: (London 1936 Submarine agreement)
1. With any merchant, surface and order to halt, boarding party checks for contraband. Exempt: Escorted, refuse inspection, troop/military transports
Prize rules disbanded by May 1940, when exactly|||||NEED INFO
Torpedo settings:
Early 1939 to October 2, 1939: Torpedo fuses are only set in patrol- can't be changed
Sep 14, 1939: All targets under 3000 tons to be attacked with impact
Sep 18, 1939: No magnetic shots
October 7, 1939: Magnetic fusing allowed with TII, TI still use impact
October 19, 1939: Impact only
November 1, 1939: Torpedoes run up to 2 m deeper than set. Set depth 2 m less than draft. Depth must be at least 3 meters, 4 m in big waves. Coup-de-grace must be set at 3 m. Means five m is the minimum draft to engage a target.
November 8: New magnetic pistol introduced. Magnetic shots to be used, depth to draft minus 1 meter. Impact only on TI fast.
January 20, 1940: Magnetic fusing: All targets less than 40,000 use 4 m depth. Targets under 1000 are not to be magnetically attacked. All targets greater than 4000, use draft plus 1
March 14: No magentic shots E of 30 degrees longitude (needs confirmation)
March 19: Fast speed on G7a forbidden. Use impact in situations where boat's concealment is essential. Same magnetic depth rules apply. Minimum distance is 500 meters. 9 seconds between magnetic fan shots, no double shots
April 11: Boats in zone O and north: Keep three bow torps set impact, one with magnetic. Attack large targets with impact a 2 meters. Double shot against destroyers, with impact at 3 meters and magnetic shots at draft-1 8 seconds later. No change for southern Norway area
April 17: 1. G7a probably runs 2+ meters deeper than set.
2. Zone O: Fire with magnetic, except inside of fjords
3. Magnetic: No salvoes, and at least 8 second interval between shots
4. Magnetic. Set depth to draft, 4 meters v destroyers, 3/4 m against submarines. Impact to 4 meters, 3 in good wx.
April 21: TII: Magnetic set depth to draft-1 meter. Against targets under 4000, set to 2 m in good weather, 3 m in bad. For impact, 3 meters against all, 2 in good wx. TI is same except for minimum depth 3 meters. All capital ships attack with 5 meters impact.
June 1: Abandon magnetic fusing, impact only. April 21 depth rules apply. Try for shallow angle hits if possible- 30 degrees is optimal
June 4: Depth to draft-3 meters, not shallower than 3 m (running depth partially fixed?). Torpedo depth has been largely corrected, +_1 m can be expected.
June 20: G7a high-speed allowed again. Set depth to draft-3, and not shallower than 3 (2 in good wx). Destroyers can now be attacked
July 30: G7a high-speed banned again (WHEN ALLOWED AGAIN?)
Feb 1942: Torpedo depth keeping completely fixed|||||DATE? Maybe May 1942?
WHEN ARE MAGNETICS REINTRODUCED? (Paper says Nov 1942 tests in the mediterranean, by April 1943 standard)
1939
Sep 1: All Polish Vessels to be attacked, no attacks on English except for defense
Sep 3: Engage British warships, merchants with prize law. Evening, French ships are targets, do not attack French merchants
Sep 4: Reiterate no action at all against passenger vessels
Sep 6: No action against anything French at all
Sep 7-Sep 12: No attacks on capital ships (Does this really end Sep 12? Sep 12 is guess based on when Courageous was sunk)
Sep 10: Enemy convoys may be attacked north of Brest, even if they include French forces. No passenger ships, even if under escort.
Sep 24: French ships are valid targets (Channel troop transports can be attacked). Passenger order still in force.
October 2: Narrow area around England where darkened ships may be attacked without warning. No attacks in baltic and North Sea. PAX ship is one with 120+ passengers, 4 or more lifeboats along side, promenade decks, etc
October 4: Darkened ships attacked w/out warning zone extended to 15 west. Any armed vessel can be attacked without warning, PAX ships not included. Save crew w/out endangering boat.
October 5: Baltic approaches between Abelo and Skagen, submerge by day due to enemey s/m
October 27: Prize rules: No boarding, sink with torpedoes (no guns/scuttling)
October 29: PAX ships in convoys are valid targets. Keep distance in any gun action.
November 17: Armed PAX ships are valid targets
December 4: No using the Channel
//1940
Mid/Late March/early April: Weseruebun: No attacks on merchants, radio silence. Warships and screening are priority, remain undetected.
April 12: Norway Uboats attack all targets (not just warships/troop transports)
April 20: All uboats pull out of zone O due to torpedo failures
//1941
April 4, 1941: Unrestricted submarine warfare against all vessels in England blockade area- excepting Finnish and RUssian
May 8: At sea refueling only during night
May 16: Cleared to attack without warning (outside blockade zone):
1. British merchants, not including unarmed/unescorted PAX ships (120 passenger rule)
2. French/Norwegian/Dutch/Belgian ships which are armed
3. All darkened ships
4. Only warships if absolutely identified as enemy or darkened
Make efforts to rescue crew provided no danger to boat
June 20: Only attack US Warships if they are 20 or more nm inside of the eastern boundary of the blockade area.
June 21: No incident at all with US forces. Only attacks on warships will be on bb, ac, or cruisers and only if recognized as enemy. Darkened warship does not count as enemy.
//AMERICAN SAFETY ZONE- where?
To mirror the torpedo depth problems, I'm using this SH3 commander mod, see post #17.
