R. V. K. Applin, Machine-Gun Tactics
“ In no phase of modern war are machine guns so valuable as during a retreat, and it is quite probable that, properly organised and handled, they may make the pursuit so difficult and costly as to render the retreat a far less dangerous undertaking than it has been in the past. It is not difficult to realise that an arm possessing such great mobility, together with rapidity and concentration of fire, before which no closed bodies can exist at effective range, will be able not merely to check and delay pursuing cavalry, but may even prevent any effective pursuit by mounted men alone. ”
