During the Russo-Japanese war, the effect of shrapnel, in spite of the mediocre matériel and the lack of shields, forced the artillery of both belligerents to seek shelter on the reverse slope of heights. When this was neglected and when batteries went into position in the open, within effective range, they were quickly silenced. The fear of shrapnel caused both sides to advance cautiously, to relinquish all close order formations at an early moment, and to employ the spade extensively. This alone was evidence of the fact that the artillery had accomplished a good deal. Moreover, it was not altogether accident that the first few of the larger Japanese night attacks occurred coincidentally with the appearance of Russian artillery matériel, which was superior both as regards numbers and power. The new German I. D. R. (par. 444), in contrast with the previous edition (II, par. 82). prescribe that the infantry attack should not be postponed until a superiority of fire has been gained. Thus, the regulations draw logical conclusions from the modern armament and seek to avoid useless bombardments of hostile positions (such, for instance, as the Russians indulged in at Plevna and the British in South Africa).
"The principal duty of field artillery is to support the infantry in the most effective manner. Its duties are inseparably connected with those of the infantry. It should, on principle, always fight the targets that are most dangerous for its infantry." (Par. 364 German F. A. D. R.).
The German Field Artillery Drill Regulations prescribe that the guns should fire over the heads of the advancing infantry (par. 375), and that single batteries should accompany the infantry attack to within close range of the enemy (par. 471). When an assault is to be made, the infantry expects the artillery to direct its fire against the point of attack until immediately before the assault begins.
"But our infantry should never be obliged to dispense with the support of artillery. The gun shields afford considerable protection, even at the short ranges. At the decisive moment the artillery should not shrink even from the heaviest infantry fire." (Par. 369 German F. A. D. R.).
