On the second day after Ernst arrived in First Town, there was nothing particularly special to do. His main focus was presiding over the preparations for war against the Boers. The Boers must be fought, and there was no other reason; it was purely a strategic consideration for East Africa.
If we don't annex the Boer land now, we will face not just the Boers in the future, but also the British.
Secondly, East Africa must use force against the Boers. There is nothing to discuss between the two parties. The Boers may surrender to the British, but they will absolutely not surrender to East Africa unless East Africa grants the Boers significant privileges, which the East African government will never agree to.
At Sweet Palace, Ernst was discussing the war against the Boers with army generals.
