The teaching of boxing was also emphasized for its life-saving value in a military sense. The maxim is taught that "every move of the boxer is a corresponding move by the bayonet-fighter." Thus, the "jab" corresponds to the "lunge," and the "counter" to the "parry." To illustrate this boxing instruction, and to apply it to bayonet-drill, a set of admirable moving-pictures was made, such clever pugilists as Johnnie Kilbane, Bennie Leonard, Kid McCoy, and Jim Corbett posing for the boxing, and Captain Donovan, the eminent English bayonet instructor, for the bayonet films, which were exhibited for instruction purposes in every navy station. Boxing tournaments, station championships, and army-navy championship bouts were given with crowded houses everywhere. Early in the winter Commissioner Camp gave directions for standardized sets of instruction in both boxing and wrestling, and as a result, in every camp in the country the groups of navy men were taught the same methods of rudimentary boxing for their value in a military sense, as well as their value as recreational sports. Soon after the thousands of young men began gathering in the navy camps, the discovery was made that not half the number was able to swim. For men destined for sea life, this was a vital handicap, and early in the spring of 1918 a campaign was launched to increase the number of swimming instructors and the facilities which were available for the instruction of the young men both in sea and river, as well as in pools and tanks, and it was decided to hold station tournaments, races, and all varieties of swimming events during the season, in conjunction with such individual instruction as it was necessary to give novices in the art of swimming. Rowing was developed during the season of 1918 to the extent which was made possible by the presence of cutters in the different stations. Wherever possible, crews were coached in the rudiments of rowing by old oarsmen. Racing between the cutter crews in whatever station was ordered for every available date, and sometimes as many as twenty boats were lined up abreast, and were shot away for the brushes between the cutter crews in some of the larger stations, furnishing a variety of sport comparable only with the brilliant scenes at the inter-collegiate races over the Thames course at New London, or the Hudson at Poughkeepsie.
