What quote explains why the Drover family left their London home in "The Demon Lover"?

Here's another quote that highlights why the Drover family left their London home:

at thirty­ two she was very greatly relieved to find herself being courted by William Drover. She married him, and the two of them settled down in the quiet, arboreal 8 part of Kensington: In this house the years piled up, her children were born, and they all lived till they were driven out by the bombs of the next war.

Of course, the "war" here refers to World War Two, and the setting of the story is London. In the quote above, the "bombs" constitute the main reason the Drover family left their London home. Mrs. Drover has only returned to the house to check on its condition and to pick up some needed items for her family.

In the story, Bowen references Mrs. Drover's "married London home," which is empty and devoid of the voices of her family. The home is compared to a "cracked cup," its dilapidated condition the result of German bombing campaigns. In fact, these campaigns were called "The Blitz." This blitzkrieg or lightning war resulted in many casualties: about 43,000 British civilians were killed. Meanwhile, about another 139,000 were wounded.

The text highlights some of the structural damage sustained by London homes during the Blitz. We are told about broken parapets and chimneys.

Because of the dangers, many civilians like the Drover family left London for the countryside during the war. Some, like Mrs. Drover, often made dangerous journeys back to their homes to pick up necessities, such as clothing or food (non-perishables).

Why did the Drover family leave London in "The Demon Lover"?

The Drover family left London to escape the bombings from German planes during World War II. These bombings were called the Blitz. Blitz was short for "Blitzkrieg," which meant "lightning war." German planes dropped bombs over London many times. In 1940, the Germans dropped bombs onto London for almost sixty nights in a row. The citizens of London had to seek shelter every night during this time. Some had backyard or neighborhood shelters. Others found safety in London Underground stations. Many people relocated to the country, boarding up their houses. The Drover family chose to relocate to the country. They hired a caretaker to look after their boarded-up London house.

When Mrs. Drover arrived at her London home, she noticed that "there were some cracks in the structure, left by the last bombing." She found her house dark because the windows were covered with boards. In the street outside her home, Mrs. Drover saw "broken chimneys and parapets." As she walked down the street near the end of the story, "the unoccupied houses opposite continued to meet her look with their damaged stare." There was evidence throughout the story of what London had become. Houses were abandoned and buildings were in ruins. Some were still standing, but damaged. Even though the bombings had stopped for a time by August of 1941, the Drover family stayed in the country. This was most likely to avoid future bombings. It could also have been because of how much destruction had occurred near their home.
