We found that for mutual and smooth co-operation in battle it is most important that batteries should operate as far as possible with the same regiments of infantry. Close touch is established, and each arm unselfishly supports the other. I often heard the expression, “our battery,” “our regiment,” and in these simple words a deep, underlying sentiment was expressed. Each battery should be capable of acting independently of the artillery regiment to which it belongs. For hill warfare mountain artillery should be allotted to infantry in the same proportion as I have suggested for field artillery. Our gun proved an excellent weapon; but our shrapnel, which was very effective against objects and troops in the open, was of no use against invisible targets, earthworks, and mud walls. Our artillery fire against villages held by the enemy, therefore, produced very little result. I consider that a new pattern of shell should be introduced with thicker walls and a heavier bursting charge; but even then the effect of such light projectiles as our field-guns fire will not be great against the earthworks which are nowadays so quickly thrown up on positions. To prepare the way for the assault on such fortifications, and to obtain any speedy result in attacking defended localities, we must have field howitzers of a modern type. They should be organized in regiments of two batteries (twenty-four howitzers), and attached to a corps as corps artillery. Finally, it is essential that every army should have a light siege-train to assist in the capture of strongly defended posts and heavy works. The organization of park units was well conceived, but the vehicles were unsuited to the Manchurian roads. I am afraid to express an opinion in favour of a further increase of mobile parks, because we were so overburdened with baggage of different kinds. I think it is preferable to improvise local parks at railway-stations and junctions, as we did in Manchuria. Small-arm ammunition rarely ran short, but there was often a great lack of gun ammunition, and after the battles of Liao-yang, the Sha Ho, and Mukden, our reserves for filling up battery and park stocks were exhausted. The average expenditure of rifle ammunition worked out as follows: For a whole-day battle for one battalion, 21,000 rounds, with a maximum of 400,000; an hour’s fighting for one battalion, 1,700, with a maximum of 67,000. The total reserve taken with a four-battalion infantry regiment was 800,000. The average expenditure per quick-firing field-gun in a one-day battle worked out at 55 rounds, with a maximum of 522; an hour’s fighting, 10 rounds, with a maximum of 210.
