Q & A

What is the significance of Halifax during the First World War as described in the script?

Halifax is an important hub during the First World War due to its strategic location and busy port, facilitating the movement of ships and supplies crucial for the war effort.

Why was the SS Mont-Blanc in Halifax, and what was its mission?

The SS Mont-Blanc was in Halifax to join a convoy of ships bound for France, carrying explosives intended to support the allies in the war effort.
