"Stand down. They won't attack for now. Nevertheless, I shall set up a proper alarm. Now watch carefully men, this may one day safe your life and that of many others. You can't always rely on having trained wolves around."
Ludmilla brings one of the horses to a tree a bit outside of the camp, towards the direction the wolves would come from. With a long rope, she ties it to a tree, and with a shorter rope, to a wooden construction that is easily build with just a few hacks of a hatched. It only took a few moments, clearly a step she has practised a lot.
"Tired soldiers tend to miss things in the darkness three times out of four, and their warnings are late and often further delayed by them argueing wether "they heared something or not". This is more reliable. Horses sleep standing, and would be easy targets out in the open. They are too big to hide. But nature is kind to them, and has given them senses far keener than that of any humans, and a sleep much lighter than many a soliders "awake" status. A well trained horse will stand where you tied it, and this construction here is sturdy enough to withstand a bit of pulling. But when a horse senses a wolf nearby - and I mean nearby, no wide in the distance - it will panic and pll itself free. The contraption will come tumbling down, and wake up even the laziest of you motherfuckers. The second, longer rope is the security rope. Horses are valueable, and we do not actually want it to run away now do we? Do you understand? Good. Then Ms.Gelibte here will build a second one, over there, and you will watch her carefully."
