Thematic try:
1. Dxc4? (2. Dd4+ Kxd4#) Kf2+! → crash or interference causing; 2. Dxc1... Over

1. Dc8! (2. Dh8! ~ 3. Dd4+; 2. - Kd2 3. Dc3+ Kxc3#) Kd2?/axb4? 2. Dh8 axb4/Kd2 (3. - bxc3) 3. Sxb4 (4. Dc3+) Ke3 4. Dd4+
1. - Ld2! (2. - L~)
2. Dxc4! Kf2? now mate!
Therefore: 
2. - Lxb4/L~ → flight, dresdnerisch, leaving battery-position instead of battery-fire!
Final:  
3. De2+ Kd4
4. Dd2+! Lxd2#, retour

Sujet: Quiet destruction of black batteries, here also in compressed form (= fourmover), but with black King as frontpiece.

Full sideline: 
1. - Sc5/Sc8/Sd6 
2. D(x)c5+! Kd2
3. Df2+ Kc3+
4. De3+! Lxe3#
