"Any number under six"

The answer given by Englishman Richard Peeke when asked by the Duke of
Medina Sidonia how many Spanish sword and buckler men he could beat
single handed with a quarterstaff.

Note the ferro-concrete ships were smaller,4600 tons, than the
Liberties, 14,000 tons, and took longer, three to six weeks, compared
to the Kaiser-built ship every ten days. And, the ferro-concretes
generally were only made late, 1944-5.
