hehe, a typical middle age strategy when attacking a fortress/city. With a siege you waited months around the fortress. A note is that probably the wall cost should be much more expensive and/or the farm land should be much wider. In History creating a wall that include also the farm land was far too costly/unpractical. And also to be effective you need soldiers watching the wall, else the attackers could easily build a hill on top of the wall and climb it. For example Rome had two big walls, the inner Servian Wall build in IV B.C. (red line) and the outer Aurelian wall (black line) build in 4 years between year 271 and 275. The big Aurelian wall where long 12 miles but also at that time the population of Rome where around 500.000 inhabitants! So like nowadays cities, the farming/food creation was done always outside the city walls. http://en.wikipedia.org/wiki/Servian_Wall http://en.wikipedia.org/wiki/Aurelian_Walls Another example the ancient Etruscan (later Roman) city of Rusellae (build on a 600ft hill) had a wide and big wall and was build around VII B.C. The walls are nearly 2 miles in circumference and consist of somewhat irregular, unworked blocks of travertine often measuring as much as 9x4 ft (2.75x1.2 m). Still within the "limited" wall area farming was just not possible a part of some trees maybe. http://en.wikipedia.org/wiki/Rusellae http://it.wikipedia.org/wiki/Area_archeologica_di_Roselle
