Abstract: The long time asymptotic behavior of the Cauchy problem solution of the Korteweg–de Vries equation with reflectionless nondecreasing initial data is studied. The data is assumed to be vanishing as $x\to-\infty$ and tend to a periodic function as $x\to+\infty$. It is shown that in a neighbourhood of the back front this solution splits in the infinite series of slow asymptotic solitons as $t\to\infty$. The explicit formulae which describe this phenomenon are obtained.
