I want to explain those hits.
On the 19th, simians robbed 2.9m gc from us, making no attempt to get a ceasefire afterwards. On the 20th, they waved their opponent. On the 23rd, we noticed the robbing and made an appropriate level of retaliation. At 100 gc per acre per hour income and over a 100-hour period, that's right about 10k gc income per 1 acre so we hit for 290 acres. We would have been just as happy to rob our money back, but allowing them to farm gold from us to fight someone else was a no-go. Frankly, they should have known better.
At any point after those 4 days have passed we are happy to return the 290 acres.
Also, their opponent is not called mercy.
