But their main use was for high-angle fire, such as that from the suburb of St Roch under the walls of Quebec.

Only howitzers capable of employing high-angle fire could usefully occupy such a position, and, as it was, our shells could not clear the crest except at pretty large elevations.

Later, when it became clear that the rebels could not be dislodged from this stronghold by street rushes, no attempt was made to shell them out of their strong position by a high-angle bombardment of plunging explosive shells.

By the time we reached the roof of the hotel Belgian high-angle and machine-guns were stabbing the darkness with spurts of flame, the troops of the garrison were blazing away with rifles, and the gendarmes in the streets were shooting wildly with their revolvers: the noise was deafening.

The aeroplane was greeted by a storm of shrapnel from the high-angle guns mounted on the fortifications, the only effect of which, however, was to kill two unoffending citizens who were standing in the streets and were struck by the fragments of the falling shells.
