if an sea zone with a naval base is hostile with enemy ships in it -- can i still build ships on that naval base?

Eight years later your post I have the game box here on my laps.
It says WWI 1914 and A&A game. So they didn’t really call it Axis and Allies. The game is super cool and since I am a great fan of the The Great War I have to say that I enjoy it even more than the other ( so far I have playes only anniversary). Kind regards. Meerko

@ragnell804 All hits must be applied. The transport is destroyed. If the Ottomans had scored only 1 hit, the Italians could have broken off the attack and saved the transport, at least for the time being.

@knp7765:

Yes you can. You are supposed to announce to the other players if you are making an amphibious assault (resulting in combat this turn) or an amphibious reinforcement (with NO combat in the contested territory this turn).
What’s more, if you do an amphibious assault, accompanying battleships can conduct shore bombardment and any defending artillery can take shots at your landing units. With an amphibious reinforcement, your battleships do not bombard and the defending artillery do not take shots at your landing units.

Battleships and defending artillery do not fire if you are offloading to a contested territory whether you conduct combat there or not.  They only fire if you offload to a hostile territory.

There is no such thing as a contested sea zone.

Personally, I don’t think this should even occur. One round of sea combat only; if the defender survives the attacker must retreat (and can still do so even after a victory).

I can understand the logic behind a land force not being allowed to retreat after a victory - they have to consolidate their hold over the conquered tt.

But why would ships remain behind in an empty sea zone, especially if they can retreat back into a friendly port for repairs and/or reinforcements from newly launched ships? Unless they wish to launch amphibious assault or enact USW why should they be obliged to remain behind and quite possibly become sitting ducks for enemy fleets? A case of being punished for success?

The anomaly occurs when a player places new ships into a sea zone occupied by enemy fleet. Should a battle immediately occur? Or should the new ships only be “launched” in his next movement/combat cycle?

You can only move land units out of a contested territory into a territory which at the beginning of your turn was either under your control or contained units belonging to you.  Since Ukraine meets neither of those conditions for Germany, Germany may not move land units there from contested Poland.  However, since Moscow is not contested, Germany may move land units into Ukraine from there.

How did things in Africa go for the CPs, and how do you feel the naval balance affected this, Chacmool?

Well like everytime in my games the northern African Units of the Allies were early shipped to the European theatre (to reinforce and/or activate Minors like Albania or Portugal) and the British Egypt Army invaded Trans Jordan.

South of the Sahara the Germans took some british colonies until the Allied armys catched them. There were some battles without hits/results in this contested areas until the Germans as defenders could decimate the attacking Aliies in South/East Africa. The naval forces of Britain were too busy bringing more troops into Arabia to push the turks back but after the colossal german/austrian naval investements they had to reduce their Mobilizatian in India to a minimum to enlarge their own Fleet in the North Sea… In the med Italy wasnt capable to answer this naval race and France had to buy Infantry…

At the End of the game strong turkish forces captured the last African tts that werent already in german control while Austrian units landed in Northern Africa.

@Tavenier:

I wish I knew how to do that!

Download the Battlemap app in the Software section of the Forum and I will teach you how.

Krieghung, thanks for the quick response.  That poor Russian battleship in SZ12 has to thread the needle through SZ11 and SZ10 even if there are no ships there and I guess once the UK Navy is gone in SZ29, you just need to start ground pounding your way through Ottoman to get into the fight.
