This info is just the lead bit of info Ancestry.com shows is available on the Fold3.com website. It's from Lt Heermans' Compiled Service Record (CSR), which will contain much useful information on his service. I don't have a membership to Fold3 yet, but if you want the record you can initiate the "free 7-day trial" to get the record and then cancel, or you can order his CSR from the National Archives at
