Chech Alexandria if you visit the mediterranean. It's a nice city with Nelson, three Dido class cruisers, a large tanker, large merchant, various smaller cargo ships, and of course destroyers lying at the harbor. Visited it myself last night, got Nelson, 4 destoyers and 2 Didos before running out of eels.
And just outside I found a task force with Nelson (again!), Rodney, 2 more Didos and King George VII. But i didn't dare to pursue them with my deck gun.
It's late 1941 and GWX 2.1.
