While the "winter offensive" failed to reach any strategic success, it certainly helped. CP morale at the beginning of this operation was 95, mine - 91. With no action, it would have been 93 and 89 respectively. After three major (and a couple of minor) battles CP and Eastern Entente are tied at 91, and the revolution has been pushed back a month. Go Brusilov!
Of course by now the front has been stabilized. German troops have poured in, and I have no choice but to fall back.
On a sadder note, Britain is now 97% aligned with rebels. I fear we may be losing their assistance soon.
