I’ve read all the rules clarifications on amphibious assaults, bridging, and rules for sea zones that start the turn hostile due to enemy ships being present in them, and I can’t find an answer. If this has been answered before, please feel free to post a relevant link to the answer.
Relevant Rules
These are (copy-pasted from the A&A 1940 Europe rulebook):
- Hostile sea zones contain surface warships belonging to a power with which you are at war.
- A transport can’t load or offload while in a hostile sea zone.
- A transport can load cargo in friendly sea zones before, during, and after it moves.
- A transport can load and offload units without moving from the friendly sea zone it’s in (this is known as “bridging”). Each such transport is still limited to its cargo capacity. It can offload in only one territory, and once it offloads, it can’t move, load, or offload again that turn.
- At the beginning of the Combat Move phase, you might already have sea units (and air units on carriers) in spaces containing enemy units that were there at the start of your turn. For example, an enemy might have built new surface warships in a sea zone where you have sea units. When your turn comes around again, you are sharing that sea zone with enemy forces. If you are sharing a sea zone with surface warships (not submarines and/or transports) belonging to a power with which you are at war, this situation requires you to do one of the following:
- Remain in the sea zone and conduct combat,
- Leave the sea zone, load units if desired, and conduct combat elsewhere,
- Leave the sea zone, load units, and return to the same sea zone to conduct combat (you can’t load units while in a hostile sea zone), or
- Leave the sea zone and conduct no combat.
Here are the two scenarios. In both, I think the crux of the matter is the same, but each scenario has some slight differences:
Scenario 1
UK fleet in SZ 110 with 3 cruisers, 1 destroyer, 3 aircraft carriers, 6 fighters, 6 transports, and at least 12 infantry and three more fighters in UK. This fleet, without moving, could use the bridge rule to bridge 12 infantry into an amphibious assault on Holland or Normandy, along with 3 offshore bombardments from the cruisers, and up to 9 fighters could also join the amphibious assault. Now, let’s say that Germany has a factory in Normandy, and on its turn decides to build a destroyer and mobilize it into SZ 110. So, the SZ will start out hostile on UK’s next turn.
Since the transports cannot load in a hostile sea zone, does this prevent the amphibious assault on Normandy or Holland? Or, does the bridging rule come into effect here, where the bridging (loading and unloading both happen at the same time without the transport moving in between) takes place once the sea battle part of the assault is over, and thus the sea zone is now friendly and the units can be bridged during the land battle part of the amphibious assault? If the German destroyer prevents the amphibious assault, then it seems silly that all Germany has to do is spend a few IPCs each turn to buy and place a single blocker to keep the entirety of the Royal Navy and Royal Marines at bay.
So, I assume the relevant choice for what to do about starting in a hostile sea zone is (1) above “remain in the sea zone and conduct combat”. And then declare the amphibious assault: move aircraft to Normandy and then declare that you have the intent to bridge 12 infantry over to Normandy after the sea zone is cleared (assuming it is cleared, which in the case would be hard to imagine it wouldn’t be with three cruisers, a destroyer, and three aircraft carriers that could be used to soak up a hit if needed). The bridging would take place in a “friendly” sea zone since the zone has been cleared before the bridging begins.
Of course, the presence of the destroyer will prevent the cruisers from getting to bombard. All the sea units will have to take place in the sea battle and won’t be available for the land battle part of the amphibious assault. No matter what the case is on bridging, that part is clear.
I know in this example, the transports could always take option (3) above and withdraw to SZ 109 (assuming it was clear of enemy surface warships), load the 12 infantry (sinze SZ 109 is also adjacent to the UK where the 12 infantry are), and come back and declare an amphibious assault, and the net result would be identical, except that now the transports are loaded with 12 infantry before the SZ battle part of the amphibious assault begins, and the transports are no longer bridging since they moved between the load and unload operations.
Scenario 2
There is a large US fleet in SZ 95 (SZ west of Italy), with US troops landed on the islands of Sicily and Sardina (which are in SZ 95). Can Italy build a destroyer and mobilize into SZ 95 and prevent the US transports in SZ 95 from conducting a bridging amphibious assault against Northern and/or Southern Italy? Or can the sea zone be cleared first during the sea battle part of the amphibious assault, and then the transports there be used to bridge those forces from Sicily and Sardina into an amphibious assault on Northern or Southern Italy?
In this case, there is one main difference than Scenario 1: there is no option (3) since Sicily and Sardina are islands contained completely within SZ 95 and so there is no alternate place to move the transports to load them up before returning to SZ 95 for the amphibious assault. If again, it cannot be done, then it seems silly to me that Italy buying a single destroyer each turn can keep the entirety of the US Atlantic fleet and all the US Atlantic marines at bay indefinitely.
It is also very clear that the transports cannot load up the troops on Sicily and Sardina and then move to a different SZ to amphibious assault there, since that would require the transports to load in a hostile SZ and then move elsewhere during combat movement to declare an amphibious assault from a different SZ, which is explicitly called out in the rules as not possible. So the destroyer does pin down those troops from being deployed to amphibious assault elsewhere, that is clear.
Crux of the Matter
The rules don’t state (or I can’t find it) when bridging for an amphibious assault as to when the transports need to be loaded. The fact that the term bridging and the rule about it is explicitly called out in its own separate line, and says “A transport can load and offload units without moving from the friendly sea zone it’s in” seems to imply that when bridging, you can “load and offload” all at once as long in a friendly SZ as the transport doesn’t move in between the load and unload, and thus it happens whenever it is appropriate to do so (in this case, right before the land portion of the amphibious assault happens). To me, it seems to be the only reason for the whole bridging concept to be introduced in the rule book at all. Afterall, if bridging is covered 100% by all the other transport rules, then why even put in the section about bridging?
Thanks!
