Shaft poised, he hurled and his spear’s long shadow flew
and it struck Achilles’ shield – a dead-center hit –
but off and away it glanced and Hector seethed,
his hurtling spear, his whole arm’s power poured
in a wasted shot. He stood there, cast down…
he had no spear in reserve.

– Homer

The Iliad, Book 22, lines 341-346. Hector lets fly spear at Achilles, it strikes the great shield crafted by the god of fire and the forge Hephaestus, but it bounces away. Since he has no spear in reserve, Hector is worried.
