Incremental Backup recovery

Hi there,

 We have made the incremental backup of an SQL server database.  Unfortunately, all the "full" type backups of the database are all destroyed.

We woul like to be able to use those several incremental backups so as to recreate the database.

The only things we have are either use an old full backup of the named database.

How can we restore the incremental backups that are available?

Thank you for your help.

AYAO
