SHRAPNEL FIRE OF FIELD 
ARTILLERY. 
BY 
COLONEL H. BAINBRIDGE & CAPTAIN H. B. STRANGE. 
Cononut Watrorv’s translation of Major-General Rohne’s essay on Section 
Shrapnel Fire of Field Artillery, lately published by the Royal Artillery Torte 
Institution, naturally causes inquiry as to how our shrapnel shell com- %™ 
pares in its effect with the shrapnel dealt with by the General. The 
object of this article is to draw such a comparison between the English 
15-pr. Mark II. shrapnel, the 124-pr. Mark II., and the German and 
ideal shrapnels of General Rohne, working out the effect by the formula 
given in his essay.

The width of the target covered at 54 yards, angle of opening 10°, is #ndosmr- 
-10 yards. Therefore area of target attacked is 20 square yards. 
The number of hits per round will be 2°8 x 20 = 56, as compared 
with 20 for the German shell. By doubling the width of the target, 
the Hnglish shell remains 56,and the German highest possible is 37 hits.
