10th intergermanland's hussars regiment in Russia

[Aida]

Hello!

Recently when looking for my family in Russia I discovered people in
Habarovsk, who probably are my cousins. This is complicated so I just
tell that the ONLY thing to know it is to check if their grandfather was
brother of mt grandgrandfather - there is no documents however and all I
could do is to find if he was fighting in 10th "Intergermanland's"
hussars regiment, and "missed" at war with Japan in 1904 year near Ussurisk.
Man's surname was Rytel (written also Ryttel or Ritter) BUT if he
decided to use another name in army (he was from Polish-Russian family)
he could use name van Kreiter after his mother or even perhaps Lavrov -
after first husband of his mother, the tzar's chamberlain. In regiment
he was officer and hide himself in faraway Russia near 1904 after a
battle (he was wounded and rescued by his Kossack's friend, then he
changed belief and name, and married Kossack's woman with 4 children -
it's all complicated. I know only that after marriage his name was Piotr
(Peter). It is important to know - if his name BEFORE was Alexander then
he is brother of my grandgrandfather. There is no documents so the only
clue is to find soldier named Alexander Rytel (or Kreiter or Lavrov)
among oficcers in 10th "intergermanland's" regiment of hussars.

Summarising - I need a list of soldiers who were enrolled to 10th
intergermandland's regiment of hussars. I do not live in Russia so I
cannot check in archives. Is it possible to find it anywhere else?
Please help me, I will be very thankful!
regards!
