While the soldier loosened the bottle the dog stood still. Then he grasped the end of the strap in his mouth and speeded away.
Like all Red Cross dogs, he had been taught to seize the strap in his mouth whenever he found a wounded man, and to return home with the news.
When the Red Cross workers saw him coming with the strap held in this way, they knew that a man lay out on the battlefield in need of help.
It was not long before the brave dog was again standing by the side of the wounded soldier, this time with the helpers he had led to the spot.
With gentle hands two Red Cross orderlies lifted the rescued man into the Red Cross ambulance which was waiting near by.
Very soon he found himself in a clean hospital bed with an army surgeon using all his knowledge and skill in dressing his wounds.
When his wounds were dressed, he looked up to see a quiet, cheerful Red Cross nurse standing by his bedside with a bowl of warm broth for him to drink.
His life had been saved by the Red Cross.
