The customary service of one The value of the knight's fee fully armed man for each five hides must already have been fixed was probably the rate at which the --twenty pounds a year.[32] newly endowed follower of the king would be expected to discharge his duty ... and the number of knights to be furnished by a particular feudatory would be ascertained by inquiring the number of hides that he held.[31]

The variation in the number of hides contained in the knight's fee.[36]

Mr Freeman's views need not detain us, for he unhesitatingly accepts Dr Stubbs' arguments as proving that the Norman military tenure was based on 'the old service of a man from each five hides of land'.[37]

We find then, I submit, that the recognized leaders of existing opinion on the subject cannot agree among themselves in giving us a clear answer, when we ask them what determined the amount of 'service' due from a Norman tenant-in-chief, or, in other words, how that 'service' was developed in unbroken continuity from Anglo-Saxon obligations.

The third point that I would raise is this. Even assuming that the amount of 'service' bore a fixed proportion--whether in pecuniary or territorial units--to the extent of possession, we are, surely, at once confronted by the difficulty that the owner of _x_ units of possession would be compelled, for the discharge of his military obligations, to enfeoff _x_ knights, assigning a 'unit' to each. A tenant-in-chief, to take a concrete instance, whose fief was worth £100 a year, would have to provide _ex hypothesi_ five knights; if, as was quite usual, he enfeoffed the full number, he would have to assign to each knight twenty librates of land (which I may at once, though anticipating, admit was the normal value of a knight's fee), that is to say, the crown would have forestalled Henry George, and the luckless _baro_ would see the entire value of his estate swallowed up in the discharge of its obligations.[38] What his position would be in cases where, as often, he enfeoffed more knights than he required, arithmetic is unable to determine. I cannot understand how this obvious difficulty has been so strangely overlooked.
