As fierce battles were still fought in Kyushu in this period, the Army Ministry estimated further 18 million rounds of ammunition would be needed and examined a plan of sending Zundnadel guns to Kyushu because it had a great deal of stockpiles of ammunition for the gun; in fact, an emergency call-up troop in Wakayama (former Kishu Domain) was dispatched to Kyushu armed with Zundnadel gun, which they had used when they served for the domain, and a rear unit including medical soldiers in Osaka Garrison were also armed with Zundnadel guns and dispatched.
この時期、九州では依然として激戦が続いており、更に1,800万発の調達が必要と見積もられていたこともあって、大量の弾薬在庫が残されていたツンナール銃を九州に送る案が検討され、実際に和歌山（旧紀州藩）の臨時召集部隊は藩兵時代から使い慣れたツンナール銃装備のまま九州へ派遣されたほか、大阪鎮台の医歩兵など後方部隊もツンナール銃を装備して派遣されていた。
