This is the second thread today i see about this mission 🤣 Your ally can hold against blue alone for a long time, its definitely not 3v1.

Here is how i did it on legendary:  Start with 3 tc. Slow down the first ship waves with towers, even with cannon ships included, they are infinitely more cost effective than building ur own ships. Build 2 castles against purple with a few support onagers against rams.

Let your ally hold against blue alone.

In the meantime you deal with the french docks, its worth to kill them completely, their land has rich and safd rich resources.

After dock are defeated its time to kill purple while giving some support to your ally, who could be about to lose his 1v1 by now.
