Ultimately, under General Winter's cautious "persuasion," Shire grudgingly agreed to authorize production at a unit price of 50,000 francs.
This price seemed very reasonable to General Winter, given that it was 20,000 francs cheaper than Russia, especially since Shire originally didn't intend to sell. Now, not only did he agree, but he also offered a discount, indicating that he had successfully negotiated and could report positively to the British Government.
However, Shire attached a condition, casually mentioning during the negotiations:
"Since we used the 'Congreve' rockets to destroy enemy reconnaissance balloons, our demand for rockets has significantly increased."
"But the production of rockets has always faced issues, leading to some accidents during the process."
This was true. Due to process issues, an explosion at a rocket munitions factory had resulted in over a hundred casualties.
