Page "Waterloo (1970 film)" Paragraph 28

To recreate the battlefield authentically, the Russians bulldozed away two hills, laid five miles of roads, transplanted 5, 000 trees, sowed fields of rye, barley and wildflowers and reconstructed four historic buildings.

To create the mud, more than six miles of underground irrigation piping was specially laid.

Most of the battle scenes were filmed using five Panavision cameras simultaneously — from ground level, from 100 foot towers, from a helicopter, and from an overhead railway built right across the location.
