For four years the Hinderers were almost entirely cut off from communication with the outer world, but they continued their labours unceasingly throughout this trying time. The girls' sewing class had, however, to be discontinued, for the very good reason that their stock of needles and cotton was exhausted. It was a time of great privation, but Anna Hinderer, although frequently compelled to endure the gnawing pangs of hunger, always managed to keep her native children supplied with food. At last relief came. The Governor of Lagos had made one or two unsuccessful attempts to relieve the Hinderers, and in April, 1865, devised a means of escape. He despatched Captain Maxwell with a few trustworthy men, to cut a new track through the bush. It was a difficult undertaking, but successfully accomplished, and one night, about ten o'clock, the Hinderers were surprised to see Captain Maxwell enter the mission-house. He brought with him supplies, and also a hammock for Mrs. Hinderer's use on the return journey. It was somewhat of a surprise to the gallant officer to find that the missionaries for whom he had performed a difficult and dangerous journey were by no means anxious to return with him. It was the more surprising as it was plain that both were in very bad health. Mr. Hinderer declared that he could not possibly leave his mission at seven hours' notice, but he joined the captain in urging his wife to go, assuring her that it was her duty to do so. At last she was prevailed upon to avail herself of the means of escape. She was overcome with grief at leaving her husband shut up in Ibadan, and her distress was increased by her inability to say 'good-bye' to the little native children to whom she had acted a mother's part. They were asleep, and to have awakened them would have been unwise, for there would certainly have been loud crying, had the little ones been told that their "white mother" was leaving them. Their crying would have been heard beyond the mission-house compound, and the news of Mrs. Hinderer's approaching departure would have spread through the town, in which there were probably spies of the enemy.
