Tobruk Fortifications

In preparation for the attack on Tobruk, Division z.b.V. Africa issued a number of detailed drawings of the Tobruk fortifications to the assault troops, to help them in overcoming these.

I am not an expert, but the fortifications look quite substantial to me. They were built by the much-maligned Italians.

Diagram 1: Schematic outline of the fortification line in the breakthrough sector.
