Attorney-General Sir John Banks, ancestor of the Bankes of Kingston
Lacy, in whose occupation, or rather in that of his wife, it was to
have its invincibility put to the test. Sir John was with the king's
forces at York in 1643 when the army of the Parliament gathered upon
the Knowle and East hills. During six weeks repeated attacks were made
by the forces of Sir Walter Earle, but without success, and eventually
the siege was raised. In 1646 treachery succeeded where honest warfare
failed. Colonel Pitman, an officer of the royal garrison, admitted a
number of Roundheads, who obtained possession of the King's and
Queen's towers. The remainder of the building became untenable by the
poorly armed defenders, who had parted with their ordnance long before
as a matter of policy.

[Illustration: PLAN OF CORFE CASTLE.]

Months were spent by the victorious Parliamentary forces in mining the
foundations and in the systematic destruction of the magnificent
defences. As we see it to-day, the actual masonry is practically in
the condition left by the explosions, so massive is the material and
so indestructible the mortar.

The sketch which accompanies these brief notes will make the plan of
the castle clear, but no description can give any adequate notion of
the strange havoc wrought by the gunpowder. It speaks well for the
good workmanship of the builders when one remembers that these leaning
towers, that appear to be in immediate danger of collapse, have been
in the same condition for nearly three centuries. The western tower
has been carried down the hill nine feet from its original position,
but is still erect and unshattered. Part of the curtain wall was
completely reversed by the force of the explosive and now shows its
