Source A: Xenophon, Constitution of the Spartans 11
'Most people think that the Spartan battle formation is very complicated, but in fact it is very easy to understand. In the Spartan formation the men in the front rank are all commanders, and each file has everything it needs to play its part. The formation is so easy to understand that no one who can recognise the men around him could go wrong: some have been given the job of leading, and the others are told to follow. Changes of formation are announced by the enomotarch's voice, like a herald's, and in this way the line is made thinner or deeper. None of this is at all hard to learn. But to keep on fighting just as well when the line has been thrown into confusion, alongside whoever happens to be next to you - that is not easy to learn, except for men trained under the laws of Lycurgus.'
Figure 1 shows a phalanx from above, with its front rank and one file marked.
Using Source A, explain two reasons why the Spartan phalanx was so effective. Make two points, supporting each with evidence from Source A.
Model answer
First, the phalanx had a very clear command structure. Xenophon says 'the men in the front rank are all commanders' and that 'some have been given the job of leading, and the others are told to follow', so everyone knew whom to obey and orders were carried out quickly.
Second, the Spartans were so well trained that they could cope with confusion. Xenophon says that to 'keep on fighting just as well when the line has been thrown into confusion, alongside whoever happens to be next to you' is hard to learn 'except for men trained under the laws of Lycurgus' - so a Spartan phalanx did not collapse when its order was broken, as other phalanxes often did.
Explanation
Most Greek hoplites were part-time citizen-farmers who could do little more than advance in a straight line; the Spartans, trained from childhood, could change formation on the word of command and keep fighting when their line was disrupted. The figure shows what Xenophon means by a file (a column of men one behind another) and the front rank, where the leaders stood. Good answers make two different points, each with a precise quotation.
