The case cited represents the maximum that was achieved in food production by any army organization, so far as I know. But that maximum was no mean thing. That division, at least, did not depend on the civil population for food.
Several trips through Serbia and Macedonia in the same year showed me what the German "economic" and occupation troops had done in those parts.
On the whole, the efforts at food production of the "economic" troops--organization of older men barely fit for service in the firing-line--had not been fortunate. The plan had been to put as much soil under crops as was possible. For this purpose traction plows had been brought along and whole country sites had been torn up. Though the soil of the valleys of Serbia is generally very rich, and the climate one of the best for farming, the crops raised in that year were far from good. Some held that it was due to the seed, which had been brought from Germany. Others were of the opinion that the plowing had been carelessly done, leaving too much leeway to the weeds. Be that as it may, the work of the economic companies was not a success.
The occupation troops did much better, however. Together with the Serbian women they had cultivated the fields on the intensive principle. Yields had been good, I was told.
In Macedonia the fields had also been put to use by the Germans, Austro-Hungarians, and Bulgars. The last named, familiar with the cultivation of the tobacco plant, were exchanging with the others tobacco for grain. Food production was also attempted by the Austro-Hungarians on the Isonzo front. But since they were fighting on their own territory in districts which still had their civil population, there was little opportunity, all the less since the soil of the Carso and Bainsizza plateaus, and the mountainous regions north of them, is not suited for agriculture on a large scale. Every _doline_--funnel-shaped depression--of the Carso had its garden, however, whence the army drew most of the vegetables it consumed.
The food that was being raised for the army never reached the interior, of course. If an organization produced more than what it consumed, and such cases were extremely rare, it sold the surplus to the army commissaries. It took men and time to cultivate the fields, and these could not always be spared, especially when the losses in men were beginning to be severely felt and when the opponent engaged in offensives. It had meanwhile become necessary to throw, several times a year, divisions from one front to another, and that, too, began to interfere with the scheme, since the men no longer took the interest in the crops they had taken when they were established in a position.
