Question about ships and defense

[Taurean]

Two scenarios.

1) I keep a cruiser in town, fortified. Town square is built on grassland or plains. When it is attacked by any military unit (sea, land air), it is "cathed in port", which i have read, if i remember correctly, reduces defense by 50%?

So, defense 6 - 50% = 3 + fortify 50% = 4.5? Very unsure about this calculation, just throwing it out there.


2) I keep a cruiser in the ocean square next to a town, on sentry/sleep. It cannot be fortified, but will operate with normal defense numbers? Sentry/sleep does not reduce defense, because it supposedly "wakes up" when a unit is viewed by it?

So the defense of 6 will be used?


Bonus question:
3) I have noticed that in cities with cannon fortress, when a unit with 1 in firepower is attacked by ships, it suddenly gets 2 in firepower. I.e. ships take 2 damage each battle turn or dice roll. Anyone else noticed this?

Here is the combat calculation.

Here, FoxAhead explains when the explosions are animated.

1) I keep a cruiser in town, fortified. Town square is built on grassland or plains. When it is attacked by any military unit (sea, land air), it is "cathed in port", which i have read, if i remember correctly, reduces defense by 50%?

The attacker's firepower is doubled, while the defender's firepower is reduced to 1. Only ground units are eligible for a fortification bonus

2) I keep a cruiser in the ocean square next to a town, on sentry/sleep. It cannot be fortified, but will operate with normal defense numbers? Sentry/sleep does not reduce defense, because it supposedly "wakes up" when a unit is viewed by it?

Sentry/Sleep has no impact on defense values.

Shore bombardment doubles defense, but this might look like the unit is dealing more damage based on when combat animations take place, per FoxAhead.
