Henry Ernest Dudeney/Modern Puzzles/153 - Transferring the Counters

Modern Puzzles by Henry Ernest Dudeney: $153$

Transferring the Counters

Divide a sheet of paper into six compartments, as shown in the diagram,

and place a pile of $15$ counters, numbered consecutively $1$, $2$, $3$, $\ldots$, $15$ downwards, in compartment $A$.

The puzzle is to transfer the complete pile, in the fewest possible moves, to compartment $F$.

You can move the counters one at a time to any compartment,

but may never place a counter on one that bears a smaller number than itself.

Thus, if you place $1$ on $B$ and $2$ on $C$, you can then place $1$ on $2$, but not $2$ on $1$.
