I think I counted all of them. Tonight's siege of 20 minutes. First 10 minutes base on full hp. Next minute base down to 80%, you can't physically make that much damage in one minute. After next 8 minutes base is on 0%. After a minute more base destroyed. Same number of BSes were shooting it at that time. A core 5 base.
A reminder from the last siege, 17 Battleships and 2 Cruisers. After hours of sieging it was brought down to 93%, then Hessians gave up because they didn't want to spend countless more hours bringing it to zero.
A reminder for the Solitaire core 4 base, 17 Battleships and it lasted for 2 hours.
In any case, I did enough explaining. People can't be bothered to see the logic. Sleep time.
