That the United States Army came to the war with Spain poorly prepared for that conflict was only natural, because its background and tradition were unique. For the better part of a century it had had a special job to do, and it had done it very well. The nation had not needed an integrated force constantly ready for a fight with a regular European power, and so in 1898 it did not have one. What it did have was an army adapted to the special needs of the innocent age which ended with the nineteenth century.
An understanding of the special circumstances which had shaped the Army can be gained from a meaty little book called Army Life on the Western Frontier , put together by Francis Paul Prucha. This book is largely made up of extracts from the reports of Colonel George Croghan, an Army inspector general from 1826 to 1845, who spent those years touring the western military posts and telling the War Department how its frontier service was getting along.
