Contribution for Canadian Identity Essay Example for Free
Contribution for Canadian Identity Essay Throughout history, Canadian aboriginals have not been recognized for their contribution, sacrifices, and involvement in Canadian war efforts. During the First and Second World Wars, many aboriginals enlisted themselves in the services for the Canadian Armed Forces. In World War I, aboriginal soldiers like Corporal (Cpl). Francis Pegahmagabow and Henry Norwest helped advance the Canadian identity with their skills and bravery in Canadian fought battles. Tommy Prince in World War II worked hard to further maintain the Canadian identity. Aboriginal soldiers courage, sacrifices, and accomplishments further developed Canadian identity in World War I and World War II. Aboriginal, Corporal (Cpl) Francis Pegahmagabow contributed his brave actions for the development of the Canadian identity. It was during his first year on the Western Front that Pegahmagabow became one of the first Canadians to be awarded the Military Medal (MM). He received his MM for his service as a messenger in battles such the Battle of Ypres. Pegahmagabow was a messenger from February 1915 to February 1916; he ââ¬Å"carried messages with great bravery and success during the whole of the actions at Ypres, Festubert and Givenchy.â⬠[1] The bravery of Pegahmagabow resulted in the halt of the German advance. The defeat of the Germans was important in Canadian history because, the world now saw Canada as an independent nation that could unite as one to fight for their rights and freedom. Pegahmagabow was important because his job of delivering messages allowed access to information about the German advance which in turn resulted in a Canadian victory. This victory gave the Ca nadians an independent identity. At the Battle of Passchendaele, Pegahmagabow added the first bar to his MM for his work of running across the land through the tough war conditions to bring back valuable information for his unit. The information Pegahmagabow provided resulted in ââ¬Å"the success of the attack and saving valuable time in consolidating.â⬠[2] The courage of the aboriginal soldier Cpl. Pegahmagabow and his excellent work contributed to the success of the Canadians capturing the Passchendaele Ridge. The victory of the battle of Passchendaele was vital in the development of the Canadian identity because the British Army had previously tried to capture the Passchendaele Ridge for three months but had not succeeded. The Canadians captured the ridge mainly because of the support and the contribution of such soldiers like Pegahmagabow, and therefore Canadians accomplished goals that other countries had failed to do. During Pegahmagabowââ¬â¢s service in the Canadian Armed Forces Cpl. Pegahmagabow ââ¬Å"captured 300 soldiers and shot 378.â⬠[3] As a result of his achievements, Pegahmagabow served as a catalyst for Canada to be able to have a presence on a global scale. Cpl. Pegahmagabow was also a skilled marksmanship, which allowed him to succeed at the battlefront. Applying these skills resulted in a high number of casualties on the German side which, identified him as a valuable soldier. This was a great advantage for the Canadian side as the strength of the enemy forces was weakened, therefore Canadians were a step closer to wining the war. This achievement by an aboriginal soldier further contributed to the Canadian identity. Henry Norwest, another aboriginal, contributed to the development of the Canadian identity by utilizing his fine skills in sniping. Norwest was given his first MM after the capture of the Pimple peak on Vimy Ridge because, Norwest showed ââ¬Å"great bravery, skill and initiative in sniping the enemy after the capture of the Pimple.â⬠[4] The sniping skills Norwest possessed led to the Canadians capturing the peak on Vimy Ridge. Killing the enemy after the capture of the Pimple peak was important because, the skillful aboriginal saved a great number of Canadian soldiers. This battle was also of great significance in Canadian history, as Canadians, once again proved to the world that they are a capable, strong nation that that can overcome obstacles regardless of the circumstances or previous failed attempts. On the other hand, with the skills of aboriginal soldiers like Norwest, the Canadians were able to conquer the Pimple. Norwest had all the essential skills a sniper needed to be successful. Norwest had ââ¬Å"excellent marksmanship, an ability to keep perfectly still for very long periods and superb camouflage techniques.â⬠[5] These skills made Norwest a lethal Canadian aboriginal sniper. Being a lethal sniper, Norwest was crucial for the development in the Canadian identity. By camouflaging, Norwest deceived the enemy and hence sniped them. The contribution of this aboriginal soldier gave Canadians the identity as strategic planners. Norwest was a skilled and fatal sniper because he ââ¬Å"achieved a sniping record of 115 fatal shots.â⬠[6] Norwest shot down many enemy soldiers and as a result, this reduced the number of enemies to fight. By reducing the number of enemies, Norwest also enabled the Canadians to be another step closer to winning the war. Canadians proved that they are a mighty, powerful and strong army because of Canadian aboriginal soldiers such as Norwest, who shot down many enemy soldiers efficiently. In the Second world war, aboriginal soldier Tommy Princeââ¬â¢s brave actions and unique ability, led to the further enhancement of the Canadian identity. In 1944 in Italy, Tommy Prince showed his bravery while spying on a German camp. While he was reporting the German activity, his communication line was damaged but, ââ¬Å"[b]y pretending to tie his shoes, he successfully repaired the break in full view of the German soldiers.â⬠[7] Princeââ¬â¢s utmost bravery led to the destruction of four German tanks, which were shooting at the Allied forces. Prince risked his life to fulfill his duty as a spy. This act of the aboriginal soldiers bravery was pivotal for the development of the Canadian identity. Canadians proved that they are risk takers and are capable of fulfilling their duty with bravery. King George VI decorated Tommy Prince with the Silver Star and ribbon, an American honour because Prince ââ¬Å"occupied new heights and successfully wiped out the enemy encampment areaâ⬠[8] in the summer of 1944 for going behind enemy lines and locating a German camp. Tommy Prince located the camp and then with his brigade, captured more than 1000 German soldiers. This technique of locating the German camp led to the reduction in the number of German soldiers. This commendable mission carried out by aboriginal soldier, Prince, was essential for the development for the Canadian identity. This mission was significant because the world saw Canadians as a strong nation that has a strong military capable of destruction of the enemies. Tommy Prince had skills which allowed him to be a part of the special airborne force with ââ¬Å"1600 of the toughest men to be found in Canada and the United States.â⬠[9] Tommy Prince possessed essential paratrooper skills. He possessed the skills of landing and crawling on his belly, with the swiftness of a snake. These skills made Prince a successful paratrooper. The aboriginal soldier applied his exemplary skills at the battle front to further enrich the Canadian identity. Soldiers such as Prince were symbols to represent the Canadians as tactful and skillful warriors. During the First and the Second World Wars, many aboriginal Canadians volunteered for the Canadian Armed Forces and contributed in the development of the Canadian identity. With the unique and effective skills of Francis Pegahmagabow and Henry Norwest the Canadian identity was enhanced. Tommy Princeââ¬â¢s courage and dedication for his nation helped Canada gain a military reputation throughout the world. The contribution, sacrifices, and involvement of aboriginals should not be forgotten because aboriginal soldiers were important for the enrichment of the Canadian identity.

Katharina and Petruchio from The Taming of the Shrew by William Shakesp
Katharina and Petruchio from The Taming of the Shrew by William Shakespeare My two favourite characters from the play, The Taming of the Shrew, which was written by William Shakespeare, are Katharina and Petruchio. I find them extremely interesting, not just because they are the main characters, but because of their contrast, chemistry and similarity between them. They go from hating each other at the beginning of the book and by the end, Katharina is obedient, the taming is complete and they are married living happily together. Petruchio has one of the main parts to play in the book as 'the tamer' while Katahrina is alongside him as 'the shrew', which in turn makes up the title of the story. Katharina is very argumentative, disagreeable and violent with all her suitors and indeed Bianca, for example the stage directions say that, "Katharina with a whip stands over Bianca, who crouches by the wall, her hands tied behind her." (Act 2, Scene 1, Stage Directions) This shows that she is extremely violent and willing to beat a confession out of anyone. Because Katharina is this way, no man wishes to marry her, although many of tried. But Petruchio comes along and he finds a challenge and, of course, a fair amount of money to profit from the venture. He is interested in the money from the dowry in particular because he enquires, "Then tell me - if I got your daughter's love, what dowry shall I have with her to wife?" (Act 2, Scene 1, Lines 119 - 120) This shows he is probably more interested in the dowry than in Katharina. Now we know that Petruchio is greedy as well as rich! A good scene to show as an example of both Petruchio and Katharina in conversation is Act 2, Scene 1. While Petruchio is in... ... none shall eat; Last night she slept not, nor tonight she shall not." (Act 4, Scene 1, Lines 182 - 183) This shows us that Petruchio is starving Katharina of her food and also depriving her of sleep. Hopefully this will turn her into a good person! Petruchio mentions one last thing near to the end of his second soliloquy, which tells us exactly why he is doing this: "This is a way to kill a wife with kindness." (Act 4, Scene 1, Line 193) In conclusion I think the two make an entertaining pair, which make the story thoroughly enjoyable for many people. The 'tamer' and 'the shrew' are amazingly similar in different ways and in the end Petruchio and Katharina bonded. Katharina becomes extremely well behaved and obedient even more so than Bianca, the total opposite to what she used to be. The taming of the shrew is complete and thus, the story ends.
