author
Best known for co-authoring Old Fort Garland, this writer is connected with a practical, history-focused account of life at a frontier military post. Reliable biographical details are scarce, which only adds a little mystery around the name behind the book.

by James T. (James Taylor) Forrest, Rosamund Slack
Available sources link Rosamund Slack to Old Fort Garland, a nonfiction work written with James T. Forrest. The book is presented as a study of daily life, duties, and conditions at Fort Garland, giving readers a grounded look at a remote military post in the American West.
Beyond that authorship credit, trustworthy public information about Rosamund Slack is very limited in the sources I could confirm. Because of that, it is safest to describe this author through the surviving book record rather than make broader claims about a life or career that are not clearly documented.
