How to Defend While Offline in Frontkrieg: Overnight Guide

The simplest way to protect your army while you sleep is to never leave it in the open field. Pull every stack into a province with a fortress, keep morale above 50, place a scout on each likely approach, and hold one mobile reserve 1-2 provinces behind the border. In Frontkrieg one in-game day equals 24 real hours, so an 8-hour night is a third of a day - more than enough time for a neighbour to run a full offensive. This guide is for players who already have a few matches behind them and keep losing ground overnight or during work hours.

Why the night is the most dangerous part of a match

Frontkrieg runs in real time and never pauses. While you are offline, everything keeps working: production, morale, enemy marches and combat. An opponent in a different time zone sees your front standing still and gets the initiative for free.

Three mechanics make this worse than it looks:

• A captured province starts at 25 morale. Even if you retake it in the morning, that region's economy stays weak for several in-game days.
• A province below 10 morale revolts and turns neutral. An overnight breakthrough hits your loyalty map, not just your army.
• After 3 in-game days without logging in, the AI takes over your nation. That is no longer an overnight problem but a lost match - details in the guide on inactivity and AI takeover.

The good news: morale recovers 40% of the gap to its target on every daily tick. One bad night does not end a match as long as you keep your key cities.

Step 1. Never park an army in open terrain

An army on the march, or sitting in a province with no fortifications, is a target with no bonuses. Before you log off, move every stack into a province with some defensive profile.

Overnight placement priority:

1. A province with a fortress (level 3 or higher is ideal).
2. Your own city with high morale.
3. A province behind a river or deeper inland, not on the border itself.
4. As a last resort, two armies stacked so they cover each other.

The worst option is stopping a march halfway because you assumed you would arrive in time. Pacing and march mechanics are covered in the guide to troop movement.

Step 2. The fortress is your main overnight investment

A fortress in Frontkrieg has 5 levels. Each level costs 10,000 money and 100 iron and takes 24 in-game hours to build at base speed. It delivers two effects that matter specifically while you are away:

• +5 province morale per level. Level 5 means +25 morale, so the region absorbs pressure instead of sliding toward the revolt threshold.
• A fortress at level 3 or higher hides your garrison count from enemy reconnaissance. Your opponent sees the province is held but cannot tell whether it holds three infantry or twenty. Attacking blind is exactly what a night raider wants to avoid.

If you can only afford one fortress, do not bury it in the rear. Put it in the province that sits on the shortest path from your strongest neighbour to your capital. General build order is covered in the article on buildings.

Step 3. Reconnaissance is your night alarm

You cannot respond to an attack you never saw. Sight radii vary widely, and they decide whether you can reconstruct what happened when you log back in:

• infantry - 90;
• cavalry - 130;
• fighter - 200;
• observation balloon - 400.

Beyond exact identification there is a detection mode: an enemy shows as a blip at 1.8 times the sight radius. A single balloon in a border province gives you coverage no infantry screen can match. Fog-of-war details are in the reconnaissance guide.

Step 4. A reserve and a railway beat a continuous line

The classic mistake is spreading every unit into a thin line along the border. At night that line breaks at one point and you wake up to a breakthrough in your rear.

A workable layout:

• 60-70% of your strength in 2-3 fortified nodes on the likely approaches;
• 30-40% as a mobile reserve, 1-2 provinces behind the border;
• a railway in the reserve provinces: it grants +50% army movement speed, so your reserve reaches the breach twice as fast as enemy reinforcements.

The reserve also covers you against misdirection: overnight strikes usually land next to your strongest province, not on it.

Step 5. Diplomacy is a free shield

The cheapest way to survive the night is to leave nobody willing to attack. One non-aggression deal with the neighbour whose army sits closest to your border outperforms two fortresses and costs zero resources.

Practical rule: before a long absence, message everyone bordering you and get the terms in writing in chat. Players rarely break an agreement on the first night - a predictable neighbour is worth more to them. How that plays out, and how to avoid being betrayed, is covered in the defensive tactics guide and the article on province morale.

A 3-minute overnight checklist

Run this list before you log off:

1. No army is standing in open terrain or halfway through a march.
2. Key provinces are above 50 morale.
3. A scout (balloon or cavalry) covers the main approach.
4. The reserve is in one stack, not scattered.
5. The production queue is full - resources should not sit idle.
6. Your diplomatic status with the most dangerous neighbour is clarified.

Three minutes on that list usually costs less than one lost province.

Frequently asked questions

Can I pause the game while I sleep?

No. Frontkrieg is a real-time strategy game, the world runs continuously, and one in-game day equals 24 real hours. That is exactly why preparing your defence before logging off matters more than any single battle.

How long before the AI takes over my nation?

Three in-game days without logging in. After that the AI runs your nation and you lose control of its decisions even if you come back later.

Do damaged buildings repair themselves?

Yes, damaged buildings self-repair at roughly 2% per hour. Full recovery from a minimal state takes about two days, so an overnight raid on your fortress is not a death sentence.

Many small garrisons or one big stack overnight?

One big stack in a fortress, plus light garrisons in rear cities. Armies scattered in groups of 2-3 units lose to a concentrated strike one by one, when together they could have held.

Summary

Defending while offline in Frontkrieg is not a separate mechanic but a discipline: armies in fortifications, morale above the threshold, scouts on the approaches, a reserve behind the line and an understanding with your neighbour. Run the overnight checklist once and logging back in stops being a lottery.
