The following excerpts are taken from an order issued by the 90th Light Division in
Libya on April 24, a short time before the start of the Axis offensive.
"Renewed accidents have shown that measures for the fencing of mine fields are still
inadequate. In the future, strong wire fences 1 meter high, or stone walls at
least 40 cm high, will be built. If shortage of men and material make it impossible to
complete this work immediately, mines already laid will be secured or removed. All
available substitute materials, such as barrels, concertina wire, tin cans,
derelict vehicles, etc., will be used to mark mine fields. If engineers are
not available, the work will be carried out by other arms.
"When a mine field is laid, the engineer unit will deliver to the commander of the
sector or strongpoint a 1:25,000 map of the mine field. The removal of mines must
likewise be reported to the sector or strongpoint commander.
"The sector or strongpoint commander is responsible for guarding the mine field and
for traffic control in its vicinity. Both he and the troops under his command must
know the exact location of the mines."
