Lyrics
oh, the sun is burning so much, and the bottle is already empty
but we have fresh courage despite the hot sun
look there comes a cool forest the captain calls halt
puts down the heavy backpack, puts together the rifles
comrades now rested food and drink gives good courage
settle down in the fresh green and forget your worries and troubles
Listen, the musicians are playing, comrades are coming in droves
when a happy song sounds the heart leaps in the chest
forward we go after a short rest happily forward always to
our happy song resounds merrily over field and forest
Our fresh, cheerful spirit is not dampened by dust or the heat of the sun
cheerfully we go through thick and thin always with a happy mind
