separate cargo transport. With very brief port calls at Yokohama and Sasebo, Japan, the ship arrived at the port of Pusan, Korea on 7 August 1950. Their equipment transport did not arrive until 9 August. The battalion immediately set about unloading the tanks from the transport and reloading them on trains for Taegu. The 70th Heavy Tank Battalion was attached to the 1st Cavalry Division and elements of Company B first went into action near Waegwan, Korea on 15 August. Their appearance, along with the 6th and 72nd Tank Battalions, on the front was welcome by the American units which had had no tanks with which to fight the North Koreans' T-34's. The battalion's employment with the 1st Cavalry Division closely mirrored their use during World War II. One tank company was attached to each cavalry (actually infantry) regiment of the 1st Cavalry Division, with platoons further divvied up one per battalion. Initial missions were route reconnaissance in order to become familiar with the terrain in anticipation of follow-on counterattack or withdrawal orders; and also show of force missions to discourage North Korean probes in the 1st Cavalry sector. Nevertheless, the 1st Cavalry Division was hard pressed by the North Koreans and had to withdraw from key terrain near Taegu between 4–9 September. Stabilizing the front over the next few days, the division and other units went on the offensive on 15 September in support of the Inchon Landings near Seoul. As the American units began to break out of the Pusan Perimeter, they suffered numerous casualties to mines that the Koreans laid in their path of advance. In one incident, as Company A spearheaded the advance on the Taegu-Waegwan road, the unit lost nearly 75% of its tanks to mines in order to clear the road for the follow-on infantry. On 21 September, tanks of the 70th Tank Battalion continued to spearhead the 1st Cavalry's northward advance, at times outpacing both supporting infantry as well as their own supply line. Tanks of Company C led the advance of Task Force Lynch (after Lieutenant Colonel James H. Lynch), consisting of troops of 3rd Battalion 7th Cavalry Regiment and other units, in their drive toward the units breaking out from the Inchon landings. On 26 September, Task Force Lynch drove 106 miles before linking up at Chongji with elements of the 31st Infantry Regiment, 7th Infantry Division, one of the units
