Lieutenant Rzhesky saves Emperor Alexander. Russian joke.

Lieutenant Rzhevsky is the hero of Soviet and Russian jokes. He is an amazing liar, a boor, a womanizer, a vulgar, a merry fellow and a drunkard.
Please write in the comments if you understand the meaning of this anecdote. Thanks in advance.
...........

1812 year. Battle of Borodino.
Emperor Alexander is watching the battle from behind the parapet.
Suddenly, a stray ball falls at his feet and begins to spin with a hiss.
His whole life flashes before his eyes.
But then lieutenant Rzhevsky appears. Famously throws the core over the parapet, and covers the king with his body. There was an explosion. The lieutenant with the king rises whole and unharmed and shakes off the ground.
Alexander says:
- Lieutenant! You saved my life, ask what you want.
Rzhevsky:
“Your Majesty, I don’t really need anything, except that General Tuchkov doesn’t want to marry his daughter to me.
The tsar, addressing the adjutant: "Come here, General Tuchkov!"
Tuchkov appears before the tsar at attention.
Emperor Alexander says:
General! I suggest you marry your daughter to Rzhevsky.
Tuchkov says:
- Your Majesty, I would love to, but I am a general, and Rzhevsky is only a lieutenant.
- You did not understand me, General, I suggest that you marry your daughter to General Rzhevsky!
- Oh, Your Majesty, I would love to, but I'm a count, and general-general Rzhevsky is nobody.
- You misunderstood me General, I suggest you marry your daughter to PRINCE Rzhevsky!
- Oh ... Your Majesty, I would love to, but I enter the court of Your Majesty, and Prince Rzhevsky ...
- You did not understand me General, I suggest you marry your daughter to MY BEST FRIEND Rzhevsky!

Rzhevsky, who up to this moment had modestly stood aside, comes up to Alexander, takes him by the arm and tells him:
—Alex! Fuck him! What, you and I can’t find women for ourselves?!!!!
