This is the rule from AA40P page #30 (thought it might help)
Does Not Block Enemy Movement:
_The “stealth” ability of subs also allows enemy ships to ignore their presence. Any sz that contains only enemy subs does not stop the movement of a sea unit. Sea units ending their combat movement in a sz containing only enemy subs may choose to attack them or not. Sea units can also end their noncombat movement in a sz containing only enemy subs."
There is an exception to this rule, however. A sub can attack any transport that moves into or through its sz unaccompanied by surface war ships, in either combat or noncombat movement. Each sub fires once (using its attack value of 2) at the transport(s), and one transport must be removed by the moving player for each hit scored. Any undestroyed transports can continue their planned movement."_
This is the Q & A from the Unofficial Errata/FAQ on the subject from 1-26-2010 (soon to be out dated)
Q. Submarines can attack transports that move through their sea zone “unaccompanied by surface warships”. Under exactly what conditions do friendly surface warships prevent sub attacks on moving transports?
A. A surface warship that starts its movement along with one or more transports and moves with them will prevent sub attacks. Also, friendly surface warships that were already in the enemy sub’s sea zone and do not move will prevent attacks on transports that move through or into the sea zone.
If you notice in the answer part it sounds like the tpt and SW Ship roles are reversed, giving extra movement to the tpt. The SW Ship doesn’t need to start its move w/tpt, the tpt needs to start its movement w/SW Ship. (This should be pulled it makes things even more confusing)
This is the last Q & A Krieghund posted, I’m not sure if it is totally replacing the above Q & A, or is in addition to it.

OK, we’re taking this thing in a different direction:
Q. Submarines can attack transports that move through their sea zone “unaccompanied by surface warships”. Under exactly what conditions do surface warships prevent sub attacks on moving transports?
A. In order to prevent sub attacks, a transport or group of transports must make its entire move accompanied by a specific surface warship or group of surface warships.
From reading post from everyone, I’m getting confused as to what is rule and what is conjecture.
Krieghund will you clarify please?*
-
If a tpt will either move into or pass through a sz containing a sub, and it moved by itself (unescorted) prior to the sub sz, or after it left it, the sub is eligible to fire its one shot @ 2, even if the unescorted move was 2 sz away from the subs sz.
-
If a tpt is escorted properly into the sz containing a sub to preform an ampib (tpt is staying), but its only escort is moving on to the next sz for an attack, is the tpt safe from the sub. It was accompanied through all its moves. Seems if you abandon it though it should not be safe.

Is this line from the 1-26-Errata still in the running:
Also, friendly surface warships that were already in the enemy sub’s sea zone and do not move will prevent attacks on transports that move through or into the sea zone.
Why I ask is if you bring in a SW Ship to attack the sub, and it submerges you would have a SW Ship in the sz (that can’t move). It would be doing the same thing (patrol) as the above statement. This shouldn’t prevent attack in the CM phase (the combat/patrol took place after CM phase), but should offer protection afterwords in the non CM phase base on the same principle as above.
- A sub can attack …… in either combat or noncombat movement. Each sub fires once (using its attack value of 2)
This could be taken 2 ways:
a) The sub gets to fire its one shot in each enemy move phase (2 shots total per sub per enemy turn).
would need to say: Each sub fires once per enemy movement phase
b) The sub only gets one shot per enemy turn and must choose which phase to fire.
would need to say: in either combat or noncombat movement (choose one)
The way you want tpt protected at all times I think its probably (a), but I wouldn’t bet the farm on it.
