The inaugural voyage of Greenpeace began when the 'Phyllis Cormack', a converted fishing vessel, departed from Vancouver, Canada, in a bold effort to protest against the Cannikin nuclear test, which was scheduled for later in the month in Alaska. The protestors, motivated by the growing global concern over nuclear weapons and their environmental impact, intended to draw attention to the potential dangers associated with such tests. The small crew, composed of environmental activists, scientists, and journalists, aimed to reach Amchitka Island, where the U.S. was conducting its controversial nuclear test, thereby placing themselves in harm's way to prevent environmental damage and encourage a wider public discourse on nuclear proliferation.

As they sailed northward, the crew faced the perils of rough, icy waters while simultaneously trying to raise awareness about their cause. Their determination was underpinned by a burgeoning environmental movement, with individuals increasingly advocating for ecological preservation and public awareness of nuclear risks. The mission was fueled by a sense of urgent morality, positioning it within a broader context of anti-war and peace movements of the time. This act of civil disobedience and activism would inspire subsequent generations to take action against environmental degradation and military practices threatening the planet.

Despite their peaceful intentions, the protest was met with governmental resistance, highlighting the conflicting interests between environmental activism and national security agendas. The daredevil nature of their mission, set against the backdrop of the Cold War, positioned Greenpeace as a pioneering organization in the realm of environmental protection, as they began to cultivate support against nuclear testing, elevating the environmental urgency on the global stage.
