Female brown/grizzly bears have a legendary reputation for fiercely protecting their young. We watched this mother with three cubs charge and back down this much larger male bear. Interestingly the male bear was minding his own business fishing in a stream about 75m or so from the sow and her brood. After forcing the male to retreat, she returned to gather her cubs and leave only to decide the male was still too close. She did a repeat performance and the male retreated again. She repeated this six times. For the final attack she literally had to run over 200m and assaulted the male who was up to his belly in water simply trying to get away. The male bear was so much larger than the female that we feared she wouldn't survive if she kept pushing her luck with him. Three orphaned cubs would have no chance of survival.
We were amazed at this series of "andfurthermore" attacks by the momma bear. We decided the boar must have been the father of the cubs and had failed to help support the household

This series of photos is from the initial encounter between the two bears. In this first shot the boar has already retreated from the creek bank where he was fishing. They are in the marsh grass at the tideline.
Here you can see the male is back pedaling into the tide flat. The marsh grass is barely visible at right of frame.
Here both bears are on all fours and you get a better sense of the difference in size. In body mass the boar was easily twice as big as the female. There was an impressive volume of roaring and gnashing of teeth. But as far as we could tell no actual contact ever occurred.
