You Win!

It is not that hard to solve this compact chess puzzle in 6 knight moves. You can give it a try and see yourself first. The harder challenge, though, is to solve it in just FIVE moves. Will you have enough patience to accomplish the goal in a series of 5 elegant moves?

Wikipedia:
Stone crosses in Central Europe are usually bulky Christian monuments, some 80–120 cm (31–47 in) high and 40–60 cm (16–24 in) wide, that were almost always hewn from a single block of stone, usually granite, sandstone, limestone or basalt. They are amongst the oldest open-air monuments. A larger variant of the stone cross, with elements of a wayside shrine is called a shaft cross (Schaftkreuz).

Chess Knights - an epitome of a kingdom. A stone cross - an epitome of a kingdom's landmark artifact. Combined together in a chess puzzle they poses a non-trivial challenge of finding the solution's shortest sequence while dealing with a non-standard chessboard. Though at first glance it might seem like an easy task, don't be misled by it. A degree of optimization challenge is hidden inside.
