The following German method of attack on permanent fortifications was
observed in Russia; the steps were--
(a) Heavy dive-bomber attack on the Soviet artillery;
(b) Selection of two or three front-line pillboxes which were subjected to
terrific box barrage;
(c) Under cover of barrage, a small party of storm troops crawls up, and
either attacks the embrasures with flame throwers, or attacks with small,
accurate, antitank guns, which put shell after shell into the same hole;
(d) When the selected pillbox has been captured, infantry advances, and
occupies the position.
It is interesting to compare the above with the method employed against
the Maginot Line:
(a) Casemates were subjected to 2 hours' heavy artillery fire followed
by dive-bombing attacks for 20 minutes;
(b) Special engineer assault detachments, under cover of antitank,
machine, and infantry guns, advanced and threw explosive charges into
the embrasures;
(c) Smoke grenades were used to protect the assault troops from enfilade
fire;
(d) Infantry advanced as soon as the casemates were captured.
The above methods are in keeping with the normal German practice of
concentrating the maximum effort at one point with the object of
effecting a breakthrough.
