RE: RiverSource Life Insurance Company
    RiverSource Variable Account 10
          Request for Withdrawal of Post-Effective Amendment No. 50 on Form N-4
               File Nos. 333-79311/811-07355
               Accession Number: 0000950137-08-011989

Dear Commissioners:

On or about September 25, 2008, RiverSource Life Insurance Company (the
"Company") on behalf of RiverSource Variable Account 10 ("Registrant") filed
electronically Registrant's Post-Effective Amendment No. 50 ("Amendment No. 50")
on Form N-4 pursuant to Rule 485(a) of the Securities Act of 1933.

Pursuant to Rule 477(a) of the Securities Act of 1933, Registrant hereby
respectfully requests withdrawal of the filing captioned above.

The Amendment No. 50 was filed to supplement the prospectus for RiverSource
Retirement Advisor 4 Advantage Variable Annuity, RiverSource Retirement Advisor
4 Select Variable Annuity and RiverSource Retirement Advisor 4 Access Variable
Annuity and increase the current fee for the Accumulation Benefit rider. The
Company has since determined the need for a new fee change at a later date and
will file another post-effective amendment. No securities have been issued in
connection with the Amendment No.50.

The Amendment No.50 has not yet become effective, but will become effective on
November 24, 2008, pursuant to Rule 485(a) of the Securities Act of 1933.
Therefore, the Company and the Registrant respectfully request that an order be
issued granting their request for withdrawal of the Amendment No.50 as soon as
is practicable.

If you have any questions, please contact me at 612-671-2237 or Boba Selimovic
at 612-671-7449.

Sincerely,


/s/ Rodney J. Vessels
