The accompanying sketches reproduce a minefield intelligence report in
the form of an overprint of an aerial photo. This report proved to be of great
value and was found to be accurate in detail when later on the minefield was
cleared. It confirms the usefulness of a study of air photographs in determining minefield
location when circumstances are favorable.
Information indicated by examination and interpretation of the aerial photo
on which the overprint was made was as follows:
Minefield 45 to 55 feet wide, 2,600 feet long. Inferred field would make it
5,000 feet long. There are four rows of mines, three yards between the first and
second, and the third and fourth rows, ten yards between the second and third
rows, five yards between mines in all rows. Mine holes (spoil) are generally
circular, indicating German Tellermines, Italian wooden box mines, or other mines
of similar shape. Definitely not Italian B2 or V3s. Mine density 4 to 5 mines
per yard of front.
Dotted lines on overprint indicate inferred continuation of minefield to
its natural anchors. Previous air cover does not actually show these mines but
the disuse of former paths across these questionable areas indicates mined
areas. On this later cover all evidence of the original mines is gone but new paths along
limit of fields verify the minefield's existence. Field probably has small vertical
fence around it.
