Dig-In For Victory!
A reference book presenting facts, figures, tables, and extracts from the Royal Engineers’ Manual of Field Engineering, 1911. It covers the construction of defensive works and bridges, demolitions, and explosives, with reproduced illustrations from the original manual. The material supports the design of late 19th- and early 20th-century wargames, and can also be adapted for medieval settings and roleplaying games.
