what is the meaning of the quote?

It means: After you have enough experience, you should pass it on.

It means that after an event everybody can reflect on the outcome and analyse the specific decisions taken to achieve the end result.

The implication in the use of the word ‘general’ is that those doing the analysis will often suggest that had they been in charge they would have done things differently and therefore achieved a better result.

The saying points up the irony of ‘being wise after the event’. Away from the immediacy of the ‘battle’, in the safety of hindsight, we re-play the event saying what ‘should’ have happened.

as i understand this, it means that during the “battle” only the “general” makes decisions and gives orders and is therefore responsible for the outcome. After the “battle” is over, is easy to say “u should have done this instead of that” and judge knowing what has already happened….

Something like : it is easy to talk, decide and judge after all is finished….

“po bitvě je každý generálem”…

(after the battle, everyone is a general)…

I guess you could compare it to:

“Monday morning quarterback”…

basically meaning, once it’s over, everyone has advice how things could have been done better….

I don’t know the quote, but it sounds like a close relative of “on Monday morning, everybody’s an all-star quarterback”; “hindsight is 20/20”: or or “everybody”s a critic”.

“On Monday morning, everyone thinks he could be a quarterback.”

When the contest (or battle) is over, everyone thinks he could have done better than the leaders who were actually there.

It means the same thing as hindsight is 20/20.

Probably after everyone is home they stretch the truth. They’re a hero in their own mind.

I think it means everyone wins and reaches the very top of the level.

in hindsight everyone can see where thing went wrong, and has an opinion on it
