Additionally, according to the , it formed subunits for its parent division in the blue group from A+54 to A+60:

Horse-drawn transport column No. 812 Horse-drawn transport workshop No. 809 Weapon park platoon No. 802

During the requisition of horses, wagons, harnesses, and transport equipment, sabotage was encountered in the areas of Nakło, Mrocza, and Prędocin, primarily from the German-descended population. In the 2nd Squadron, mobilization proceeded without major issues. However, there were shortages of uniforms for some reservists due to delays caused by overloads in the supply depots in Bydgoszcz.

On August 25, the squadrons were dispersed from Bydgoszcz; the 2nd Squadron to Osielsko and Niemcz, the 1st Squadron to Osowa Góra and Czyżkówko. The regrouping of the entire regiment was completed by August 27. The 15th Artillery Regiment headquarters was located in Morzewiec, the 1st Squadron in Jachcice, the 2nd Squadron in the Janowo farm, Smukła Seminary, and the carbide factory, and the 3rd Squadron in Samociążek. Training and team integration of the horses was initiated. On the evening of August 27, the 3rd Squadron was moved to the Luchowo Forestry Lodge, where it arrived on the morning of August 28. By August 30, the 3rd Squadron command had recognized the area of Trzemiętowo as the future operational zone for the squadron. On August 30, an alarm was declared, and the regiment took up combat positions. The 3rd Battery of the 15th Artillery Regiment positioned near Witoldowo, the 2nd Battery near Wojnowo, and the 1st Battery near Osowa Góra. The 3rd Battery of the 16th Artillery Regiment secured an advanced position, providing support to a company outpost from the 61st Infantry Regiment in the village of Nowa Dąbrówka. Observation points were established: the main one in Kruszyn and the forward one in Nowa Dąbrówka. The 2nd Squadron advanced the 4th Battery to the Chmielów area. The 3rd Squadron advanced the 9th Battery to the Wierzchucice and Wierzchucinek area.

Combat operations

Defense of the Bydgoszcz bridgehead On September 1, the 15th Regiment carried out artillery fire on the border region where units of the German 50th Infantry Division had infiltrated, in the area of Wiktorówko, Badecz, Wysoka, Łobżenica, and Wyrzysk. The 2nd Squadron of the 15th Regiment fired on the German "Netze" Infantry Brigade near Nakło, halting their movement.

On the morning of September 2, due to lingering fog, the regiment did not fire on German troops but was instead shelled by German artillery at the observation point of the 9/15 Squadron, resulting in some casualties. After the fog lifted, the 3rd Squadron of howitzers shelled two German batteries in the area of Teresin farm and Gliszcz village, forcing them to cease fire and possibly destroying two guns. The 8/15 Squadron shelled two advancing columns of German infantry observed from Trzemiętowo. Around 2:00 PM, the 9/15 Squadron came under inaccurate German artillery fire but managed to return fire with approximately 260 shells before retreating to the main defensive positions. In the evening, the observation post of the 3/15 Squadron was shelled, and at 6:00 PM and 7:00 PM, the 15th Regiment shelled German positions at hill 120.

During the night of September 2–3, the 15th Regiment, excluding the 3rd Squadron, regrouped from Mochle and Morzewiec to positions west of Bydgoszcz to support the 61st and 62nd Infantry Regiments. The 3rd Squadron crossed the bridge at Smuka on the Brda river and provided support to the 59th Infantry Regiment on the northern section from Borówno Lake to Gądecz village. After some adjustments, the 3rd Squadron was reassigned to support the 62nd Infantry Regiment in the Szczutki area, near Łącznica Manor. The 2nd Squadron took up firing positions near Osowa Góra.

On September 3, starting at 07:00 AM, the German 50th Infantry Division attacked the Bydgoszcz bridgehead three times in the Tryszczyn and Szutki area. The 3rd Squadron of the 15th Regiment effectively shelled German infantry in the Mochle and Wojnowo areas. On the Tryszczyn-Wojnowo road, concentrated fire from the 3rd and 1st Squadrons destroyed many German trucks transporting infantry and supplies. The 1st Squadron shelled the Nakło-Bydgoszcz road, while the 2nd Squadron fired towards Wtelno and Koronowo. In the morning, German artillery heavily shelled the infantry's defensive positions. The 8/15 Squadron destroyed a German observation post and vehicles carrying infantry. In the afternoon, the 2nd Squadron's positions were detected by a German reconnaissance aircraft and shelled by German artillery, while the observation post of the 1st Squadron and its ammunition column were bombed. The 1st Squadron lost several gunners and horses.
