In 1915, the 1st Canadian Division was recognized as a fighting force, for holding their ground against a new type of warfare: chlorine gas. It was at the Battle of Ypres where the Germans released 160 tons of poisonous chlorine gas on a large section of the Western Front. As the thick yellow clouds of chlorine gas drifted over British and French forces, soldiers started to drop dead, and many tried to run from the area.

Luckily, a soldier from the Canadian Lines discovered that by pressing urine-soaked clothes over their noses and mouths the gas would not penetrate their bodies. By the end of the day, there was a four-mile gap between the allied lines.

The Canadian Division worked all day and night to attempt to fill the gap between the allied lines. On April 24, the Germans attacked in an effort to wipe out the enemy once and for all. Another violent attack was followed by a gas assault. This time the target was the Canadians. In a matter of two days, the Canadian Line experienced 2,000 deaths and 3,000 wounded. Even though the Canadian Division suffered so many loses, it was the first time that a small Canadian force caused a major European power (Germany) to withdraw.

First paragraph is fine.

See if that reads OK to you.

That sounds pretty good. Thanks a lot =]

In 1915, during the Battle of Ypres, the 1st Canadian Division faced a new form of warfare: chlorine gas. The Germans released 160 tons of poisonous chlorine gas on a large section of the Western Front, causing British and French forces to be enveloped in thick yellow clouds. As a result, soldiers began to die and many attempted to flee the area.

However, a soldier from the Canadian Lines made a discovery that would save lives. He found that by pressing urine-soaked clothes over their noses and mouths, the gas would not be able to penetrate their bodies. This makeshift solution helped the Canadian soldiers withstand the gas attack.

Nevertheless, the gas assault left a significant impact. By the end of that day, a four-mile gap had formed between the allied lines. The Canadian Division worked tirelessly throughout the day and night to attempt to fill this gap. However, on April 24, the Germans launched another attack, aiming to eliminate the enemy once and for all. This time, the Canadians were the primary target, and they faced both a violent attack and a new wave of gas assault.

Over a span of just two days, the Canadian Line suffered heavy casualties, with 2,000 deaths and 3,000 wounded. Despite these losses, the Canadian Division achieved a significant milestone. It was the first time that a small Canadian force had managed to successfully cause a major European power, Germany, to withdraw.
