Overrun rolls and results:
2 CP is destroyed
4 CA Java is destroyed
3 CA Sumatra is destroyed
10 CA De Ruyter escaped
4 CP is destroyed
Pretty impressive overrun.
When CA rebases, Germany intercepts (2 rolled) it in North Sea and sends NAV to box 2. Allied roll is 7.
CA De Ruyter sinks in North Sea.

If your attack is going really well, it's an ambush.
