This weekend many commercial genealogy websites are giving free access to some of their military and veteran’s records. Not everything is free but enough is available that you may find records for some of your family. Most are only available until Monday evening. All three of these websites will try to get to to subscribe to see other non-military results.
World Vital Records Military Collection is available until may 28th. For Revolutionary War pensions I found file numbers but then it linked to records on another website which wanted me to subscribe.
The My Heritage collection only has some of their military records for free. Other search results want you to subscribe. Look for the small green “Free” tag after you do your search.
Ancestry has the most free records available but they are mostly WWI and WWI records. Plus Ancestry always gives you too many search results.
