1. As Heine said, a small army can defeat a larger army with wit and strategy. Also, your army is spread across Italy whereas the majority of Constantinoples army was focused on Rome.
Wit and strategy? When Anarchy's orders are as detailed as Napoleon's at Aushwitz, I'll believe your story. But all it is in this is "send army force A to location B." There is no strategy in this game on a micro scale.
2. Just because they don't have a military navy, that doesn't mean they can't have supply or transport ships. Also, since it was a small army, They could've easily snuck through enemy territory. After all, I have visited that region of Italy and the terrain there is very rugged and good for hiding out.
Wait. So, they have ships under government control, sending troops to places and sending their supplies to the troops under orders of the government...but the government has no ships? It's a contradiction. The navy includes transports, not just warships.
3. Could have been Roman built forts.
EQ said they weren't over AIM.
4. How do you know how many men the fort required? It can take two men to operate a cannon effectively.
"Massive" forts according to EQ. "Massive." You cannot man the entire fort chain if they are all "massive." Secondly, they would have been outnumbered and outgunned.
5. See number 1.
Whatever.
6. Boats could've come under the cover of darkness. Also see number 2.
Unless they were ordered to come under the cover of darkness, they didn't. EQ cannot give one force the strategic advantage by giving his own orders to the troops.
7. They could've easily brought small amounts with them and gotten more money from citizens they conquered.
Unless it was in the orders, they didn't have it.
8. This is probably the lamest argument here. This is a story NES, anything realistic is possible here and bribing the guards is not by any stretch of the imagination unrealistic.
It's not unrealistic, granted. However, it is an entirely new, unexpected element to the game. I have a prosperous economy. Can I bribe the Constantine general in Southern Italy?
