"The time is out of joint; O cursed spite, \ That ever I was born to set it right!" William Shakespeare (1564-1616), "Hamlet" act I, sc. v, l. 188.

The goal is to make the half-battery on the 4th rank ready to fire by a move of a wN. There are two ways to do that. On 1. Ne3? (2. Qc4#) d5! defends, so the solution blocks this pawn by 1. Nd6 with the same threat and allowing Black to capture wNd6 in two ways 1.. Nxd6, Qxd6 2. Qc5#, Ne5# also 1.. Qf7, Qf1 2. Nf6#, Nf2# with changed battery-mates.
