DELETION (*7, 4-2)

We found a TWO for shelter from the sun-
So unrelenting was the summer heat-
And looked out at the sparkling Gulf of ONE,
Where long ago the Turks had met defeat.

(Do you want to go on to THREE = sin and TWO = in? In NPL terms, those are not deletions but one curtailment and one beheadment. You could still use all eight words in one puzzle, but you’d have to warn the solver that two-unspecified-steps were a curtailment and beheadment, not deletions.)
