Several references have already been made in Tactical and Technical Trends to
the use by the enemy of metal spikes - "crowsfeet" - dropped from the
air on landing fields and motor transport roads.
In addition to dropping several hundred spikes on one of our airdromes
in North Africa, according to a recent announcement antipersonnel mines, said
to resemble pencils and fountain pens, were also released.
It was reported that a skirmish line of all available men provided the
best method of removing spikes, and shrapnel and bomb fragments. Shells and
dud bombs are flagged for subsequent removal. In the case in question, the
engineering unit furnished sand bags for collecting stakes and the flags
for spotting the location of duds or holes.
Following each of these attacks, it was indicated that commanding officers
must prescribe that all available personnel report for duty.
