The organization, equipment, and deployment of the Iron Brigade was something that would take several months to organize. Which Bruno had anticipated well in advance. After all, there was a reason he proposed its creation in October of 1904, rather than waiting for the following spring when the Bolsheviks would have already occupied Saint Petersburg and its port.
As for the Tsar, he was quickly alerted to the formation of the Iron Brigade, and that roughly 6,000 German Volunteers, consisting of an Infantry Brigade, and an attached Artillery Regiment would be sent to Russia to aid in the war effort.
The numbers seemed rather lacking as far as the Tsar was concerned. Especially when the enemy's numbers were quickly approaching the 100,000 mark. And showed no signs of slowing down, but at the end of the day any help was welcome.
