The Belgian Antarctic Expedition (1897–1899), led by Adrien de Gerlache aboard the Belgica, was the first expedition to overwinter in Antarctica, and it marked the beginning of the Heroic Age of Antarctic Exploration. Although plagued by hardship, it produced important scientific results and unforgettable stories of survival.

Here are the key events:

⸻

🚢 Preparation and Departure
• Leader: Adrien de Gerlache (Belgium).
• Ship: Belgica, a converted Norwegian whaler.
• Crew: A multinational team of 19 men, including:
• Roald Amundsen (Norwegian) – first mate, later first to reach the South Pole.
• Frederick Cook (American) – ship’s doctor, later controversial Arctic explorer.
• Departed Antwerp, Belgium in August 1897.

⸻

🌊 Voyage South
• Sailed via South America, stopping at Rio de Janeiro, Montevideo, and Punta Arenas.
• Reached the South Shetland Islands and then pushed further south into the Bellingshausen Sea.

⸻

❄️ Exploration and Discovery (Early 1898)
• Conducted scientific surveys: charting coastlines, collecting biological and geological samples.
• First confirmed entry into what is now called the Gerlache Strait (named after the leader).
• Collected extensive data on Antarctic wildlife, including penguins and seals.

⸻

🧊 Trapped in Pack Ice (March 1898)
• Belgica became trapped in the Bellingshausen Sea near Peter I Island.
• Despite attempts to cut the ship free, the ice closed in — forcing the crew to spend the winter of 1898 in Antarctica.
• This was the first recorded Antarctic overwintering (unplanned and nearly disastrous).

⸻

🌑 The Long Polar Night
• Crew endured 70 days of continuous darkness.
• Extreme cold, scurvy, and mental health crises took a heavy toll.
• Deaths: Norwegian sailor Carl Wiencke died (washed overboard) earlier in the voyage; later, sailor Emile Danco died of heart failure during the winter.
• Morale sank — de Gerlache himself became incapacitated by illness.

⸻

🩺 Cook and Amundsen’s Leadership
• Frederick Cook improvised medical and psychological strategies:
• Treated scurvy by insisting the men eat raw seal and penguin meat.
• Encouraged exercise and exposure to daylight when possible.
• Roald Amundsen kept morale up, helping with sledging and maintaining discipline.
• These efforts likely saved the crew from mass death.

⸻

🪓 Escape from the Ice (January–March 1899)
• When the sun returned, the crew spent weeks cutting channels through the ice with saws and explosives.
• By March 1899, the Belgica finally broke free after more than a year trapped.

⸻

🏠 Return to Civilization
• Returned to Punta Arenas, Chile, in March 1899, and then to Europe.
• Despite hardship and limited exploration, the expedition was hailed as a success for:
• Scientific achievements (meteorology, magnetism, biology, geography).
• Pioneering survival in Antarctic winter conditions.
• Inspired the next wave of explorers, including Amundsen himself.

⸻

✅ In short:
The Belgian Antarctic Expedition’s key events were:
• The Belgica becoming trapped in pack ice (1898).
• The first Antarctic overwintering, with deaths, scurvy, and near disaster.
• Cook and Amundsen’s crucial roles in survival.
• The eventual escape and return in 1899.

It was a mission of hardship rather than conquest, but it proved humans could survive the Antarctic winter, making it the true starting point of the Heroic Age.
