Derry Fire responded to a reported fire at 30 High St. Thursday afternoon.

On arrival, firefighters saw heavy fire in the back corner of a large Victorian=style house. Crews went to work, and a second alarm was requested for additional manpower.

Crews had difficulties accessing the fire that spread in the walls and to attic. A third alarm was requested so that fire crews could be rotated due to the heat the firefighters faced.

Mutual aid response came from about 14 cities and towns to the scene or for station coverage.
