The following is a list of frequently asked questions, as gathered from the EU3 forum...

How do I transport my army overseas?

(see the manual; Naval transport of armies, p. 112)[1]

To do this, you need one transport ship for each regiment in the army. Move the fleet to a seazone, and move your army into the same zone.

Note that you cannot load troops onto ships in port, only onto ships at sea in a coastal seazone.

To unload, either sail the fleet into a port you control or have access to (the troops will be unloaded automatically), or move the fleet to a coastal seazone, select the army (via the tag on the right of the fleet information panel) and move the army ashore.

I have taken all of my enemy's provinces. Why can't I annex them?

(see the manual; Annex, p. 80)[1]

The only countries you can annex are:

  • Countries that have only one province, or
  • Pagan countries
  • Since HTTT.png HTTT 4.1, you can also annex non-pagan countries with more than one province, if the total war score cost of their provinces is less than 100.
  • You can also annex a country of any size that has just broken away from you in a war of independence.

So if you have soundly beaten France and occupy all of their 25 provinces, you can not annex due to this One Province Annexation rule. You can take part of their land and come back for the rest later.

Note that if the enemy controls a province that it doesn't own, you aren't considered to be occupying all it.

Sometimes the enemy will own provinces that lie within your terra incognita, and unless you send conquistadors you will not be able to conquer those provinces. You can check your warscore and if it is less than 100%, it means you have not taken all of their provinces, and it is very likely that one or more are unknown to you.

If your warscore shows 100% but you still cannot annex, then this will be because the country has overseas colonies below city size, which you possibly cannot see.

Why are my regiments getting no reinforcements?

Normally, if you have a depleted regiment (one with less than 1000 men), it will receive reinforcements automatically on the first of every month, until it reaches full strength again. If this is not happening (the regiment remains depleted), there are several possible reasons:

  • You have run out of manpower. If your total manpower (displayed on the top left of the main screen) reaches zero, and your regiments' demand for men is greater than your monthly manpower gain, some of your regiments will not be reinforced.
  • Your army support is too low. If your support slider (in the military screen) is set to less than 100% support (slider to the left of middle), none of your regiments will receive reinforcements, no matter what your manpower.
  • Your army is suffering from attrition. Check the small number under the skull at the top right of the army information box; if is greater than 0%, your army may be losing men to attrition faster than it is reinforced. If for example you send 10 regiments into a province with an effective support limit of 5, the army will steadily attrit down until it is under 5,000 men (500 per regiment), then reinforce above 5,000, then attrit back down again and so on. This is a dangerous situation in the long term as it can bleed away your manpower for no gain. Note that some unsettled tropical provinces have an effective support limit of 0, and will slowly destroy any regiment placed there.
  • In tropical provinces, in addition to max attrition being +5, the support limit is -5 as well. (i.e. an African province with supply limit of 6 is required to keep 1 regiment at full strength, 7 for 2, 8 for 3, and so on.
  • Seasonal changes in northern or mountainous regions can also temporarily affect attrition rates, additional -2% for mild winter, -5% for severe winter

Why do my troops keep running away?

It's always annoying to have 5,000 of your troops run away from 2,000 opponents. There are several reasons why this might happen:

  • Your troops have low morale. Their moral is shown by the green/red indicator at the top left of the army information box - if it is mostly red (because your troops are newly raised or recently defeated), your army will likely run away in the first few rounds of combat.
  • You have your army support set too low. Unless the support slider in the military screen is all the way to the right, your troops will have less than their maximum morale - which makes them prone to running away a lot. Note that the morale indicator shows morale only as a proportion of the maximum for the current slider setting - it does not show whether your maximum morale is lower than it could be.
  • You have lower Land technology than your opponent. Maximum troop morale rises steadily with increasing land tech.
  • You have poor Domestic policy slider settings. Setting your domestic policy to favor Quantity, Naval or Serfdom will reduce your army morale.
  • You are badly outnumbered. While a small, high-tech army with a good general can cut swathes through outclassed opponents, its morale can be worn away in a long battle. If the enemy army is ten times the size, it can take ten times the morale hits before it routs.
  • You recently went bankrupt. Bankruptcy ruins the morale of your armies for several years afterwards (no-one wants to die for Monopoly money).

The AI is slaughtering my armies. Why is this happening?

It's even more annoying to send 5,000 or more troops against 2,000 opponents and watch them get cut to pieces without even inflicting significant losses in return. There are several reasons why this might be so:

  • You are using outdated troops. As you research land technology, you will gain the ability to recruit more modern troop types, but to actually do you have to select them by clicking the appropriate troop type bar in the military screen (this will also automatically upgrade your existing regiments). If you take obsolete troops up against modern ones (because you forgot to upgrade, or you have lower land technology than your opponent), expect to get hurt.
  • You are using infantry against cavalry. Early in the game, cavalry are much more effective at killing things than infantry. Later on (above about land technology 15), it starts to even out, but low-tech infantry are lance fodder.
  • Your regiments are understrength. If you have many more regiments than your opponent, only some of them will be able to fight at once. The amount of damage a regiment does is proportional to its remaining strength - so 10 500-man regiments will usually lose badly to 5 1000-man regiments.
  • You are fighting in bad terrain. Attacking up hills or across rivers gives a -1 penalty to your attack score (see the manual; Making an Attack, p. 103).[1] Attacking from sea to land, or using cavalry in woods gives a -2 penalty. These penalties are indicated by coloured boxes saying "-1" or "-2" on the battle resolution display.
  • You are fighting a lucky nation. Lucky countries get a bonus to their leader abilities.
  • The enemy army has a good leader. Leader skills are added directly to unit ratings for attack and defence, so an early unit with a 0/0 shock rating becomes a 5/5 when led by a shock-5 general. Shock skill is particularly important in the early part of the game when fire effects are minimal. Net leader skills (difference between one side's general and the opponent's) are indicated on the battle resolution display in boxes with flash (fire) or lightning bolt (shock) symbols. If you see a high shock value in your opponent's half of the battle resolution display, consider running away!

My king died, and suddenly I'm a junior partner. Why did this happen?

(see the manual; Offer Royal Marriage, pp. 70-71)[1]

If you have one or more royal marriages when your king dies, there is a chance that the heir to the throne will be the king of another country. That monarch will then rule both countries in a Personal Union. As the junior partner in the union, you will be limited in your diplomacy, and you will pay half your monthly tax income to the senior partner, as if you were a vassal.

How do I get out of it?

Up to In Nomine (IN.gif), the junior partner in a personal union could not attempt to break free by declaring war on the senior partner. This is however possible in HTTT (HTTT.png).

See Getting out of a Personal Union for specific things to do to get out of a Personal Union as soon as possible.

I have good relations with another country, but why can't I ally with them?

All countries are limited to a maximum of two voluntary alliances.
If you already have two (or more) allies, the only countries you can make new alliances with are your vassals and countries in a personal union with you. All other alliance attempts will be marked as "impossible", even if you have an honourable reputation, a royal marriage, +200 relations and a high-DIP monarch.

I sold a province to my ally, and suddenly I'm bankrupt?

This is a well-known bug, not fixed as of 1.1. Attempting to use the "sell province" diplomatic function can result in a number of unwanted outcomes, including you unintentionally paying war subsidies to the intended purchaser at a rate equal to the intended purchase price, per month - which tends to bankrupt even large empires rather quickly. If you want to sell provinces, save the game first.

Why are my manufactories going up in cost, even with inflation of 0%?

This happens because every time you build a particular manufactory it goes up in cost. So the second Refinery will cost more than the first, even with no inflation! This is working as designed.

Why do I have so much difficulty trading?

Trading requires a lot of work to be very successful, there are really 2 ways, in one you must focus on it and get a lot of money from it, the other you get less but you don't need to limit yourself as much. Tips-

  • You need a low badboy (reputation) for trade in foreign COT's, if you keep a badboy of even 10, you will have difficulty in foreign COT's. (The penalty does not exist when you trade in your own)
  • You should get the three trading ideas to allow you to get more merchants and being able to hold them there.
  • A king with a high admin skill will help. (You cannot control this)
  • Not Having a COT that is not a core province, for this will give you a penalty. (in 2.1, on 1.3 it is a different culture COT)

Why is everyone attacking me?

Have you been a badboy? If you have been annexing your neighbours, declaring war or taking over provinces, you have been acquiring a negative reputation which will only disappear slowly. Your reputation is visible from the Diplomacy tab. The higher your reputation the more likely that your neighbours will gang up on you.
