How does Longfellow describe Paul Revere in the seventh stanza?

Longfellow describes Revere as impatient, determined, and eager to begin his ride.

Meanwhile, impatient to mount and ride,
Booted and spurred, with a heavy stride,
On the opposite shore walked Paul Revere
Now he patted his horse's side,
Now gazed on the landscape far and near,
Then impetuous stamped the earth,
And turned and tightened his saddle-girth;
But mostly he watched with eager search
The belfry-tower of the old North Church,
As it rose above the graves on the hill,
Lonely, and spectral, and sombre, and still.
